i configured a single vrf on my PEs;on my PEs,i can see all the CE routes and on my CEs i can see the routes from the other site.
the problem here is that CEs cannot ping each other.the PE directly connecting to one site can also not ping the routes of the other remote site.
when i use the sh ip bgp vpnv4 all command on the PEs i get to see all the routes,but they just wont ping.
