Description
Disable 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 header with a TTL value of 255, regardless of the IP packet TTL. When the router acts as the penultimate router, it pops the MPLS header without writing 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.
Required Privilege Level
