So I am having problems getting EIGRP to establish neighborship for a CCNP based lab. I have the WAN side configured for eBGP and also have a static default route pointing at the cloud (which is actually a router running eBGP.) but EIGRP fails to establish neighborship. I pasted all the configs, can anyone tell me what I'm doing wrong? I kind of feel that the Cloud (since its a router) needs to tunnel network added to the BGP table but what doesn't make sense is how does DMVPN work in the real world with real ISP's without advertising someone's corporate VPN Tunnel network?
