Getting back up on the horse toward passing BSCI, I've dusted off my lab routers and I want very simply for BGP to start advertising a loop back network from Router Chris to Router Brian. (On Family Guy I guess those two don't interact much but I don't think that's the culprit here.)
Brian's config:
!
router bgp 360
neighbor 201.1.1.2 remote-as 790
!
Brian's sh ip bgp summary:
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
201.1.1.2 4 790 18 18 1 0 0 00:15:14 0
Chris's config:
!
router bgp 790
network 25.1.1.1
network 25.1.1.1 mask 255.255.255.0
neighbor 201.1.1.1 remote-as 360
!
Chris's sh ip bgp summary:
BGP router identifier 25.1.1.1, local AS number 790
BGP table version is 47, main routing table version 47
1 network entries and 0 paths using 89 bytes of memory
BGP activity 1/0 prefixes, 23/23 paths
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
201.1.1.1 4 360 19 19 47 0 0 00:16:36 0

So the two have neighborship in the ESTABLISHED state, but network 25.1.1.1/24; active on Chris's Loopback0 interface, doesn't show up at all in Brian's routing table. I've configured it manually in router config mode, so what have I neglected to do here?

To the original poster: I am having difficulty in treating your question as having merit given the ID that you have adopted. I suggest that you start over and choose an ID that suggests that you have respect for these forums.
There is inconsistency in what you have configured and I believe that this is causing the pproblem. You have configured:
network 25.1.1.1 mask 255.255.255.0
however the address suggests a mask of /32 and the mask suggests that the fourth octet should be 0. It is hard to know what to change without seeing what is configured on the loopback, but I believe that you need to either change the address or change the mask.
