One cool thing about BGP is you can peer between non-connected routers. In this video, I'll show you how to do this.

Howdy,

Just like to say your videos are great, very clear and precise.

I have a question about iBGP. In a lab I am running, I have three networks, each in a separate AS and each internally running OSPF.

The problem I have is that the external BGP neighbour (AS2) is able to ping the internal IP's (Of AS1) when it has AS1 as it's defualt route.

How do I prevent my border routers allowing internal IP's to be addressable to external AS's?

*these are not advertised in BGP, just ospf.

That is not possible. It is easy to do bgp peering but it never be work.
