Hello, Yeah. The GRE thing is fine. I am doing mpls. Instead of mpls in the core - I try to use GRE tunnel between the Provider Edge. >From the Customer Edge to the Provider Edge I am not doing tunnel so you won't see tunnel there - it just doing BGP. CE can't ping each other even though they have the route in the routing tables Traceroute dies at the PE Default routes for the suns are just the CE LAN ip address.

So PE1 and PE2 are your CE peers? I've done GRE tunnels across the internet with study partners, and it works just fine. can your CE routers ping eachother? If not, where does the routing break down. traceroute is useful here. What are the default routes that your Sun machines are using? troubleshooting 101.
