I have 2 routers connect to 2 ISPs:
ISP1 router--------My router1------My router2---------ISP2 router
My router1 configuration:
router bgp 11111
no synchronization
no bgp log-neighbor-changes
network 17.11.0.0
neighbor 69.231.141.153 remote-as 12345
neighbor 17.11.25.11 remote-as 11111
no auto-summary
My router2 configuration:
router bgp 22222
no synchronization
no bgp log-neighbor-changes
network 17.11.0.0
neighbor 167.13.192.145 remote-as 54321
neighbor 17.11.25.12 remote-as 22222
no auto-summary
I noticed my router2 routing table keeps changing and caused connectivity
problems. It sometimes gets routes from ISP1 router. How does it happen? My
router2 does not have direct session with ISP1 router. Anyone can help me?
Here is part of the routing table on my router2:
B 217.170.115.0/24 [20/0] via 167.13.192.145, 2w1d
B 216.221.5.0/24 [20/0] via 167.13.192.145, 1w1d
B 210.51.225.0/24 [20/0] via 167.13.192.145, 2w1d
B 209.136.89.0/24 [20/0] via 167.13.192.145, 2w1d
B 209.34.243.0/24 [20/0] via 167.13.192.145, 2w1d
B 205.204.1.0/24 [20/0] via 167.13.192.145, 6d23h
B 204.255.51.0/24 [20/0] via 167.13.192.145, 2w1d
B 204.238.34.0/24 [20/0] via 167.13.192.145, 2d14h
B 204.221.17.0/24 [20/0] via 167.13.192.145, 2w1d
B 204.17.221.0/24 [20/0] via 167.13.192.145, 2w1d
B 203.238.37.0/24 [20/0] via 167.13.192.145, 2w1d
B 203.34.233.0/24 [200/0] via 69.231.141.154, 00:00:43 (why this???)
