Conside the following scenario
A----------B-----------C
If A Shows the following entry :
Local Outgoing Prefix
tag tag or VC or Tunnel Id
17 Pop tag [T] 100.1.1.30/32
If B shows the following entry :
Local Outgoing Prefix
tag tag or VC or Tunnel Id
17 Pop tag 100.1.1.30/32
The outgoing Tag of A shows that B has asked A to pop
the uppermost tag
However, if you look at B it shows Local tag as 17 .
Local Tag is the tag advertised to its upstream LSR's.
However, A shows that B has asked A to POp the tag .
Is the above interpretation correct ? If yes router B
should have shown some kind of indication in the local
tag saying that to pop the tags in the upstream LSR's
( however, this is not the case ?
How do you correctly interpret the above two outouts
of show mpls forwarding.
