One of my customer uses Ethernet0/0, instead of Loopback as update source. (See following sample configuration)
interface Ethernet0/0 ip address 200.110.60.1 255.255.255.0 router bgp 12345 bgp log-neighbor-changes network 200.110.60.0 neighbor 144.200.200.239 remote-as 1234 neighbor 144.200.200.239 ebgp-multihop 2 neighbor 144.200.200.239 update-source Ethernet0/0 ip route 144.200.200.239 255.255.255.255 Serial1/0 However, ISP thought it's loopback address, so in their configuration, they has a static route: ip route 200.110.60.1 255.255.255.255 Serial 4/1 However, internet users could ping to the router, but could not access servers which in the same subnet of Ethernet 0/0. For example, 200.110.60.2 Apparently, the network 200.110.60.0 was not advertised by BGP. Could anyone tell me why, and give some suggestion? Temporally, we asked ISP change the static route to: ip route 200.110.60.0 255.255.255.0 Serial 4/1 It's working now. But BGP should be able to advertise the route, am I right? So what's the problem here?
