Hi Damien, The PEs are all Juniper routers. CE1 is cisco router 3745, CE2 is Juniper router M20. We are using link service PIC to do the IPIP tunnel.
The tunnel between CE1 and PE2 is already established and I can ping CE1 using CE2 facing interface at PE2. Cheers, Benny Damien Holloway <[EMAIL PROTECTED]> wrote: What type of routers are they? To do IPIP you need a service/tunnel pic.

I have a IPv4 VPN network that runs IPv6 over IPv4 like the topology below: CE1 ----- PE1 -------MPLS ------- PE2 ------- CE2 The IPv6 over IPv4 tunnel is established between CE1 and PE2 using IP IP tunnel. From PE2 to CE2 we use native IPv6. Packets from CE1 never reach CE2 but from CE1 we can ping to PE2 interface that is facing CE2 and vice versa. If I sniff the ICMPv6 packet from CE2, it shows that CE2 is already received the packet and replied them. When I checked at interface tunnel on PE2 using firewall filter, the packets is already transmitted to the tunnel interface but never arrived at CE1. Is this topology is applicable? Any info is highly appreciated, Thanks, Benny --------------------------------- 8:00? 8:25? 8:40? Find a flick in no time with theYahoo!
