Anand, For each full duplex flow, DE requires one RC at one peer and another at the other peer. This requires a double-ended exchange to activate using RC. Where the IPSP has a conifgured AS (see 4.3.4.3 second paragraph), no RC is required in ASPAC, in which case, the AS at each end is known by both sides and a single-ended exchage _could_ be possible. That is all that it is saying. --brian Anand N Ilkal wrote: (Wed, 24 Mar 2010 08:17:57) > > Hello, > In Double Exchange mode under IPSP-IPSP model. what should be the > behaviour in case Remote Peer sends ASPAC without any Routing Context? > Section 4.3.1 in RFC 4666 indicates the Single Exchange behaviour can > be followed - > extracts from RFC 4666 - > "ASPTM messages.
