2.12 Setting MPLS TTL Processing Modes

This section describes how to set the MPLS TTL processing modes.

2.12.1 Establishing the Configuration Task

Applicable Environment
The S9300 provides the following MPLS TTL processing modes:
l
Issue 04 (2011-12-26)
Run the display mpls graceful-restart command to check information about GR of all
protocols related to MPLS.
Run the display mpls ldp [ all ] [ verbose ] command to check information about LDP.
Run the display mpls ldp session [ all ] [ verbose ] command to check information about
the LDP session.
Run the display mpls ldp command, and you can view that the state of Graceful Restart
is On. That is, LDP GR is enabled.
Run the display mpls ldp command or the display mpls ldp session verbose command,
and you can view the values of LDP session Reconnect timer, Neighbor-liveness timer,
and LSP Recovery timer.
If the ingress node is configured with the uniform mode or enabled with the IP TTL
propagation function, the IP TTL decreases by one at each hop on an MPLS network.
