Subject: Recording AS Hops in RRO - discussion

Hi,

As per RFC 3209, there exists a provision to add AS number hops in ERO as 
sub-objects.

This definitely has usage in inter-AS LSPs, so a user may configure AS hops to 
direct an LSP through a specific AS path.

However, from what I have checked, currently there is no provision to record AS 
numbers in the RRO.

If this provision already exists and I missed it, do point me to it. Else, do 
you think this would be useful to have ?

We say that it would be useful to aggregate /modify RROs sent out of an AS for 
confidentiality. Would adding AS number sub-oject to RRO help ?
Would it also help in identifying loops involving LSPs traversing same AS more 
than once ?

thanks,
