can some one help me to understand correct steps to follow to configure inter-as TE FRR. I followed the cisco doc but it is not clear.
Is it the concepts that you don't understand (different IGP topology information not shared) or is it the implementation part?
It''s referred to implementation part because the cisco DOC isn't clear. The doc isn't clear (http://www.cisco.com/c/en/us/td/docs/ios/12_0s/feature/guide/gsintast.html)
Can you please give more information about the topology and some cfg, which routers are in which AS. For your backup tunnel, did you use loose-hop?
The static route is used on the MP (and all along the path towards the PLR) in order for the RESV msg to get to the ASBR.
Forced flooding-link is used between the ASBR in order to have these links in the TED (TE database).
