What It Means

This LSP event indicates that a router, forwarding packets to the egress router, was not configured for RSVP.

Cause

This LSP event might be caused when a router not configured for RSVP forwards an RSVP packet toward the egress router without decrementing the Send_TTL value in the RSVP common header. The next downstream router detects that the Send_TTL value and the IP_TTL value are different, and generates this LSP event. Note that two different routers generated the same error message at different times.

Action

Configure the router in question with RSVP.
