Basic BGP Configuration - Part 3

CCIE 24290 from defaultroute.co.uk demonstrates the initial configuration of BGP. The demonstration includes eBGP and iBGP configuration plus bringing a network into the BGP process. The demo discusses the 'next-hop principle and how to work around that challenge.

Hi mate

i did configured same confug. but when i try to ping R4 from R1 it doesnt work. trace route stop at R2. I can ping R1 and R4 from R2 and R1 route for R4 in BGP table with *> also i did next hop self.

To mominisNile:ospf is one of the ways to solve the issue of ebgp route reaching R1.its not the only one.So u decide which one is best option.ospf should be the last one you would conside her here.

one more thing ospf hellos are only sent to ospf peers via multicast.if r4 is not using ospf.then r4 is not a peer.

hi .is there any more video that follows this one.because it seems to be a big topology and i was expecting much more after this video.You are doing such a good job.

Correct me if I'm wrong, but would you really want to enable OSPF on R2's EBGP interface to allow R1 to see the route to 150.1.1.0? Wouldn't that cause OSPF to send out hello packets to the EBGP interface of R4? We don't want to send out hello packets to R4 right since that's our ISP.
