GMPLS Commands
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.
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.
