Hi Benjamin, Hello, Thanks you for your answer Nick With a symmetrical routing design, If I anderstand well, only the session setup ( first few packets ) will be sent through the HA3 link, so it should not be so dramatic. Once the session has been established, the PA which owns the session, will be able to analyse and forward the packet without always sending packets to HA3 link. Am I right ? [NC] You've got it! In my original question, what about the 10ms RTT between our 2 PAs ? [NC] You'll have to look at your specific applications and their tolerance for latency. Since this 10ms RTT will typically only affect the session for the first few packets, I don't anticipate any issues. Thanks for your help - Benjamin Thanks, Nick
