Silly question time, but how are you judging that time on - router has stopped receiving prefixes on show ip bgp sum (or neighbor). Or are you defining it having a full feed with some other metric? I would always track the times for: a) bgp stability b) cef table population (show ip cef sum) c) hardware population (show mls cef sum) - Jared ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Yes - router had no iBGP sessions before. Sessions are pre- configured on the ASR1006, and then turned up on all 3x route reflectors simultaneously where I track 'sh ip bgp summary' on the ASR1006. It's crass, and you can feel the CPU working as it downloads all 3x full sessions at the same time, but that's the time the router takes. The 1st session that comes up takes about 10 seconds longer to complete than the remaining two; but all sessions are done in under a minute.
