Platform 65k SUP2-T / 10Gig P
R1--iBGP--R2 <====eBGP====> R3---iBGP---R4
R2 and R3 linked over 10Gig ethernet type circuit - DC interconnect.
I'm currently advising a client on doing away with its IGP, OSPF. The organisation changes fairly constantly and OSPF doesn't help with its lacking capabilities in the filtering department, and even more than that, one often ends up with heaps of bewildering redistribution. Fortunately the org is not mission-critical happily accepting 30-60sec failover.
The overarching topology is simple and total number of prefixes currently stands at less <100.
So we're doing away with OSPF, but what I wanted to please ask was how much tuning is now available for eBGP and iBGP, I mean in terms of fast-failover whats' the quickest I can get these peering to failover / reconverge
Thank you
