Description
Enable normal time-to-live (TTL) decrementing in a VRF routing instance. You configure this statement once per routing instance, and it affects only RSVP-signaled or LDP-signaled LSPs in the routing instance. When this router acts as an ingress router for an LSP, it pushes an MPLS copies the TTL value from the IP packet header. When the router acts as the penultimate router, it pops the MPLS header and writes the MPLS TTL into the IP packet.
Default
Normal TTL decrementing enabled; the TTL field value
is decremented by 1 as the packet passes through each label-switched
router in the LSP. This statement explicitly configures the default
behavior for the VRF routing instance and is useful for overriding
the no-propagate-ttl configured globally on the router
at the [edit protocols mpls] hierarchy level.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
