Hi, I have a query on RFC4558 & RFC4206, regarding "Maintenance of RSVP HELLO adjacency over a FA adjacency". I see that: 1) RFC3209 talks about HELLO adjacency over a directly connected numbered interface. 2) RFC4558 further extended HELLO adjacency over directly connected unnumbered interfaces. Both above documents specified IP TTL value of the HELLO as 1 -- because nodes were directly connected/adjacent. So when an LSP is tunnelled through a FA-LSP, is there any IETF document which covers procedures to be followed for non-adjacent/out-of-band HELLO adjacency ? RFC4206 does talk about procedures to be followed for PATH messages. i.e. avoiding IP TTL vs. RSVP TTL check in this case. Does these procedures applies to HELLO messages as well ? Thanks & Regards Nells K.S
