Subnets are not needed, chances are it is a failure of no auto-summary. Autosummary is on by default. router#show ip route x.y.106.122 Routing entry for x.y.106.120/30 Known via "connected", distance 0, metric 0 (connected, via interface) Redistributing via bgp abcd Advertised by bgp abcd route-map connected-to-bgp Routing Descriptor Blocks: * directly connected, via Serial2/0/0:0 Route metric is 0, traffic share count is 1 router#show int Serial2/0/0:0 Serial2/0/0:0 is up, line protocol is up Hardware is Multichannel T1 Description: by the perception of illusion we experience reality Internet address is x.y.106.122/30 router bgp abcd no synchronization bgp log-neighbor-changes bgp dampening redistribute connected route-map connected-to-bgp redistribute static route-map static-to-bgp no auto-summary ! ip classless router#show ip bgp x.y.106.122 BGP routing table entry for x.y.106.120/30, version 11186014 Paths: (1 available, best #1) etc If you have no auto-summary turned on, then there might be a bug or more probably, some sort of typo or mismatch (pilot error). /vijay
