hi guys, this is my first post with my first question:
Basically, can someone explain to me the bellow `sh ip bgp sum`s ?
The setup is quite simple: 2x 2811 routers that connect to 2x ISPs and that have themselves (the routers) set as iBGP Peers. Filters are only set on the out to isp (so that i don't become a transit AS), not between the iBGP peers. HSRP enabled on both internal int of the routers (BGP shouldn't care though about it)
Question1: x.x.x.76 gets 268025 prefixes (subnets) from neighbor r.r.r.r & x.x.x.96 gets 268323 prefixes (subnets) from s.s.s.s. Why does x.x.x.96 say that he gets only 119006 prefixes (routes) from x.x.x.76 and not the 268025 that x.x.x.76 from r.r.r.r ? Same for the other Router (x.x.x.96).
Question 2: shouldn't the maximum of bgp activity paths equal (example for x.x.x.96) to 268323+119006+1(=287330) and not the 4391402 that it reports ?
Question 3: A prefix is a subnet in the `sh ip bgp` table right ?
Question 4: A path is every row in the `sh ip bgp` table for a distinct prefix/subnet, right ?
Question 5: What are (also example for x.x.x.96) 316682/46726 & 4778733/4391402 ?
Question 6(most important): If these two routers are connected to 2 ISPs via 2 different bandwidth connections (let's say x.x.x.96 has more bandwith to the metropolitan network), how can i tweak bgp so that all traffic (incoming&outgoing) from/to metro IPs comes/goes via him and notx.x.x.76 ?
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
