BGP peer issue

rcrimp — Thu, 13 Aug 2015 00:20:07 GMT

I am attempting to configure BGP routing but have been unable to get the 2 routers to form a peer. I am able ping the router interfaces with no issue. When i enable debug i get the following messages. Is there something i am missing in the configuration?

*Aug 13 00:16:28:999 2015 H3C BGP/7/DEBUG:

*Aug 13 00:16:52:999 2015 H3C BGP/7/DEBUG:

Hi,

You need to enable the peer for the desired address families, in this case:

bgp 65000
peer 172.16.20.2 as-number 65001
#
address-family ipv4 unicast

peer 172.16.20.2 enable

best regards,Peter.
