no mpls propagate-ttl

[m-geisler]

Hello everybody,

I am just wondering if there is any 'show' command (except 'traceroute') to verify whether 'mpls propagate-ttl' is on or off

Thanks

Mike

Mike,

"mpls ip propagate-ttl" is enabled by default. The best way to find out whether it is enabled or not is to do a "show runn | incl propagate".

This will tell you whether the TTL propagation is disabled for transit traffic, locally originated traffic or both.

Hope this helps,

Hi,

By default, the mpls ip propagate-ttl command is enabled and the IP TTL value is copied to the MPLS TTL field during label imposition.

I am not kidding, but i think that you have no way except to do show run :).

router#sh run | i ttl

no tag-switching ip propagate-ttl forwarded

router#

Hi,

As the other posts indicated

show run | i propagate-ttl

There are 2 options for dis-abling the ttl

forwarded and local where forwarded option allows the propagation of packets originated by the local device.
