[c-nsp] MTU / BGP

[CiscoNSP List]

Thanks for your help Mark+Adam.


Mark - I adjusted connecting port tcp/mss to 1000, but unfortunately made no difference (BGP still flapped on both sessions to the old RR's)


Adam - debug output below from both 1 x ME and 1 x ASR...the only thing that stands out to me(But Im tired :) ) is the excess latency/jitter line(s)...hopefully hotmail doesnt crew the formatting:



ASR RR:

Hi,

Once the session is up do you see all the routes being exchanged between the new MEs and old RRs?
How many routes do the new MEs receive/advertise from/to the old RRs? (just would like to rule out the max number of prefixes trigger for session reset)

Let's try "debug ip bgp x.x.x.x" on both ends.
To find out what each end thinks is the reason for the session reset.
