Re: Difference between administrative weight and autoroute

Hi Paul

Thanks for the reply.

I feel i know what autoroute announce does, However there is a metric
associated with the autoroute as well. Need to know the difference between
autoroute metric which is configured using *'**tunnel mpls traffic-eng
autoroute metric'* and Administrative Weight.

I am pretty confused, hope not confusing you this time :)

Regards
Sundeep
