RE: BGP question [7:27879]
Stephen, BGP is not like other routing protocol where you use the network command to run bgp on that interface. The network command is used to announce networks that the router know about to its neighbor. This means that you must already have a route on your router either via Static, IGRP, RIP, etc before BGP will announce this route to its neighbor. I think that's what happen when you turn on RIP. Try using the network command for your other directly connected network then you will see BGP announce it to its neighbor. router bgp 200 network ethernet network or router bgp 200 redistribute connected subnet Not having the whole configs, I'm not sure where you pick up the default route. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stephen C Sent: Friday, November 30, 2001 12:37 PM To: [EMAIL PROTECTED] Subject: BGP question [7:27879] When configuring BGP on a singlehome net, everything I read says the basic config commands are ... for S 0\0 to S 0\0 (200.200.1.1 to 200.200.1.2) wire 200.200.1.0 Router-A(config)#router bgp [as#] Router-A(config-router)#network [subnet#] Router-A(config-router)#neighbor [subnet#] remote-as [as#] now filling in the blanks Router-A(config)#router bgp [200] Router-A(config-router)#network [200.200.1.0] Router-A(config-router)#neighbor [200.200.1.1] remote-as [100] unless I configure RIP on the same wire I get nothing.

RE: BGP question [7:27879]
I am supprised that no one has explained this in normal terms to you so far. Here goes. Under normal operation (in your case) BGP will not advertise a network unless it learns it from an IGP first (in BGP's case it will consider a static route an IGP route). You can make BGP advertise a network not learned by an IGP but this is only sugested to be done when all internal routers are running IBGP. Then you would use the no-synchronization command to allow BGP to advertise these networks. THe other alternative is to set a static route pointing to null0 (ip route 192.168.1.0 255.255.255.0 null0) and have BGP advertise that network to its EBGP neighbor. OR run an IGP like RIP. That is why it works when you add rip routing. Hope this helps.
