Harry The setup i place in my lab is, CE1 ---(FE-Vlan)---- PE1 --------(E1)------PE2 --------(FE-Vlan)-----CE2 And here is my config of PE1....same will be on PE2 (some basic config has been supressed).... VPNs are UP over GRE but no communication....even PING with 32 or 56 Bytes got failed. interfaces { e1-0/0/8 { mtu 2000; encapsulation ppp; unit 0 { family inet { address 192.168.200.5/30; } family mpls; } }
