Context
config>router>gmpls>lsp>working-path
config>router>gmpls>lsp>protect-path
Description
This command specifies the bandwidth to be signaled for the path of the GMPLS LSP. Bandwidth is specified in terms of the RFC 3471 signal type name.
If an empty path is configured or the first hop TE Link is not configured, the system will automatically select a TE Link to use for a GMPLS LSP path based on the lowest available TE Link ID with a matching bandwidth (if a bandwidth is configured for the GMPLS LSP). During a data-bearer link allocation request, an RSVP-requested GMPLS LSP BW can be either a non-zero value as per RFC 3471 signal-type, or it can be zero). There are the following cases:
a) When a TE (or TE/DB) Link is configured in the related hop, LMP checks whether the related port BW is the same (exact match) as the requested BW, and allocates the port (provided any other checks are OK).
b) When the related Hop is empty: LMP finds a db-link port to the peer node matching the requested BW, and allocates it.
a) When a TE (or TE/DB) Link is configured in the related hop, LMP allocates the port (provided the other checks are OK), and provides the port BW to RSVP to use in signaling.
b) When the related Hop is empty, LMP finds the first available db-link to the peer (based on lower db-link Id), and allocates it and provides the port BW to RSVP to use in signaling.
The no form of the command udates the bandwidth to zero.
Default
0
Parameters
signal-type
Specifies the RFC 3471 name of the signal type representing the requested bandwidth for the GMPLS LSP path.

Syntax
lsp-init-retry-timeout seconds
no lsp-init-retry-timeout
Context
config>router>gmpls
Description
This command configures the initial GMPLS LSP path retry timer.
The new GMPLS LSP path initial retry timer is used instead of the retry-timer to abort the retry cycle when no RESV is received. The retry-timer exclusively governs the time between two retry cycles and to handle retrying of a GMPLS LSP path in a failure case with PATH errors or RESVTear.
The no form of this command returns the timer to the default value.
Default
no lsp-init-retry-timeout
Parameters
seconds
Specifies the time, in seconds, between retry cycles.
path
Syntax
path path-name
no path path-name
Context
config>router>gmpls
Description
This command creates the path to be used for a GMPLS LSP. A path can be used by multiple GMPLS LSPs. A path can specify some or all hops from ingress to egress and they can be either strict or loose.
Paths are created in a no shutdown state. A path must be shut down before making any changes (adding or deleting hops) to the path. When a path is shut down, any GMPLS LSP using the path becomes operationally down.
The no form of this command deletes the path and all its associated configuration information. All the GMPLS LSPs that are currently using this path will be affected. A path must be shut down and unbound from all GMPLS LSPs using the path before it can be deleted. The no path path-name command will not result in any action except a warning message on the console indicating that the path may be in use.
Parameters
path-name
Specifies a unique case-sensitive name label for the LSP path.
Values
shutdown
Syntax
[no] shutdown
Context
config>router>gmpls>path
Description
This command disables GMPLS LSPs using the path. All services using these GMPLS LSPs are affected. Paths are created in the shutdown state.
The no form of this command administratively enables the path. All LSPs, where this path is defined as primary or defined as standby secondary, are (re)established.
Default
no shutdown
hop
Syntax
hop hop-index node-id node-id [te-link te-link-id] {strict | loose}
no hop hop-index
Context
config>router>gmpls>path
Description
This command specifies the node ID of the hops that the GMPLS LSP should traverse on its way to the egress UNI-C router.
The GMPLS LSP ingress and egress node IDs can be included as the first and the last hop. This is necessary when interoperating with the Alcatel-Lucent 1830 PSS.
The no form of this command deletes hop list entries for the path. All of the GMPLS LSPs currently using the path are affected. Additionally, all services actively using these GMPLS LSPs are affected. The path must be shut down first in order to delete the hop from the hop list. The no hop hop-index command will not result in any action except a warning message on the console indicating that the path is administratively up.
Default
none
Parameters
hop-index
Specifies the order of the hops. The LSP always traverses from the lowest hop index to the highest. The hop index does not need to be sequential.
Values
node-id
Specified the node ID of the transit GMPLS LSR. This can be an IPv4 address or a 32-bit unsigned integer identifier of the data plane switching node of the adjacent UNI-N.
loose
Specifies that the route taken by the GMPLS LSP from the previous hop to this hop can traverse through other LSRs. Multiple hop entries with the node-id are flagged as errors. Either the loose or strict keyword must be specified.
strict
Specifies that the LSP must take a direct path from the previous hop router to this router. No transit routers between the previous router and this router are allowed. If the IP address specified is the interface address, then the LSP must use that interface. If there are direct parallel links between the previous router and this router, and if the system IP address is specified, then any one of the available interfaces can be used by the LSP. The user must ensure that the previous router and this router have a direct link. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.
peer
Syntax
[no] peer peer-node-id
Context
config>router>gmpls
Description

This object allows, for example, end-to-end load balancing across the set of data bearers corresponding to a set of gLSPs. A gLSP is bound to an overlay tunnel group by a gLSP tunnel name at both the head end and the tail end UNI-C nodes of a gLSP. A sender-address may be optionally configured for the tail end of a gLSP in case overlapping GMPLS LSP tunnel names are used by different head end nodes.
The no form of this command removes the tunnel group. All memebers of a GMPLS tunnel group must be removed and the tunnel group shutdown before the tunnel group can be deleted.
Default
no gmpls-tun-grp
Parameters
gmpls-tunnel-group-id
Specifies the identifier of the GMPLS tunnel group.
Values
description
Syntax
description description-string
no description
Context
config>gmpls-tun-grp
Description
This command configures a description string for the GMPLS tunnel group.
The no form of this command removes the description.
Default
no description
Parameters
description-string
Specifies a text string of up to 160 characters describing the GMPLS tunnel group.
far-end
Syntax
far-end ip-address
no far-end
Context
config>gmpls-tun-grp
Description
This command configures the IP address (GMPLS Loopback Address) of the far-end UNI-C router.
The no form of this command removes the far-end address
Default
no far-end
Parameters
ip-address
Specifies an IPv4 or IPv6 address of the far-end UNI-C router.
Values
member
Syntax
[no] member member-id
Context
config>gmpls-tun-grp
Description
This command configures a member of a GMPLS tunnel group. A member of a GMPLS tunnel group is a GMPLS LSP. All members of a tunnel group must have the same bandwidth. Up to 16 members may be configured for each GMPLS tunnel group.
The no form of this command removes the member.
Default
no member
Parameters
member-id
Specifies the identifier of the GMPLS tunnel group member.
Values
glsp
Syntax
[no] glsp session-name name
Context
config>gmpls-tun-grp>member
Description
This command binds a GMPLS LSP as a member of the GMPLS tunnel group. The session name is used to identify the GMPLS LSP. This is the LSP name of the GMPLS LSP.
The no form of this command removes the member.
Default
none
Parameters
session-name name
Specifies the session name of the GMPLS LSP.
Values
shutdown
Syntax
[no] shutdown
Context
config>gmpls-tun-grp>member
Description
This command disables or enables the member of the GMPLS tunnel group.
Default
shutdown
member-threshold
Syntax
[no] member-threshold threshold
Context
config>gmpls-tun-grp
Description
The member-threshold is the number of member GMPLS LSPs that must be operationally up before the GMPLS tunnel group is considered operationally up. If that number is not reached, then the GMPLS tunnel group is taken operationally down.
A member of a GMPLS tunnel group may be treated as down for one of the following reasons. These reason codes are recorded in the tmnxGmplsTunGrpMemberTable in the MIB:
The no form of this command reverts the member threshold to 0.
Default
0
Parameters
threshold
Specifies the minimum number of GMPLS LSPs that must be operationally up before the GMPLS tunnel group is considered operationally up.
Values
mode
Syntax
mode mode
Context
config>gmpls-tun-grp
Description
This command sets the operating mode of the GMPLS tunnel group.
In load-sharing mode, traffic is load-shared across the member GMPLS LSPs of the tunnel group. The same hashing algorithm is used as for LAG (see the "LAG and ECMP hashing" chapter of the Alcatel-Lucent 7450 ESS OS / 7750 SR OS / 7710 SR OS Interface Configuration Guides). If load-sharing is configured, then all of the GMPLS LSPs must terminate on the same far-end node. All of the ports used by GMPLS LSPs must be equivalent in that they must have the same named QoS policy, bandwidth, etc. Once more than one gLSP is associated with a tunnel group, the QoS policy / scheduler policy cannot be changed for any of the ports. All GMPLS LSPs must be unprotected end-to-end. Segment protection is allowed for GMPLS LSPs associated in a load sharing mode tunnel group.
In active-standby mode, only one member gLSP can be associated with the tunnel group.
The no form of this command removes the member.
Default
load-sharing
Parameters
mode
Specifies the operating mode of the GMPLS tunnel group.
Values
active-standby — Sets the operating mode to active-standby.
load-sharing — Sets the operating mode to load-sharing.
Default
shutdown
Syntax
[no] shutdown
Context
config>gmpls-tun-grp
Description
This command administratively disables or enables the GMPLS tunnel group.
Default
shutdown
type
Syntax
type [head-end | tail-end]
Context
config>gmpls-tun-grp
Description
This command configures whether a GMPLS tunnel group is at the head-end or tail-end of the set of member GMPLS LSPs from the perspective of GMPLS LSP setup. It can only configured if the GMPLS tunnel group has no members; for example, if none have yet been configured.
Default
head-end
Parameters
head-end
Sets the GMPLS tunnel group to operate as a head-end.
tail-end
Sets the GMPLS tunnel group to operate as a tail-end.
