If BGP rides on TCP, how are the TCP sessions built if BGP itself is used as the IGP?
This question should come after the next one.
How does this affect the hierarchy of the network since all iBGP speakers must be fully meshed?
You're assuming not only that it has to be fully meshed, but that each router does not have a single hop distance to every other router. You don't *have* to fully mesh it. You can use confederations, or you can use route reflection. Or both, or some other method I didn't think of. Or, and this is more likely case, if you only have a few routers, and each has a direct link to every other one, (Very likely with 2 or 3 routers), you can make a full mesh without problems. As our network grew here, we used these methods to avoid an IGP until we needed it. (Right now, we're using OSPF, if you're curious.) -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.0 for non-commercial use <http://www.pgp.com> iQA/AwUBNiOYfGfkezbzToVaEQLNIgCg33nj1D8ZPEp8Wq4dOcqGLKxyX5YAnjAE hPeREC0BqrLLruAfhQQLI3sx =SsjW -----END PGP SIGNATURE-----
