Release Information Statement introduced in Junos OS Release 10.4.
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
routing—To view this statement in the configuration.
