[j-nsp] PFE-forwarded IPv6

[Truman Boyes]

Hi Jonathan,

You can use any of your DPCs. On non-MX JUNOS routers you need to have tunnel pics (ie. packet that needs to be encapsulated/tunneled/etc will switch from PFE to PIC to PFE). MX does not require this because you can make the DPC perform tunnel-services. 

Once you create the tunnel-services function on the DPC, you can associate the IPIP tunnel interface with the tunnel service. Ie. Change the IPIP.0 to: ip-3/0/0.0, which corresponds to your FPC 3 PIC 0, port 0 unit 0. 

Take a look at:

Search for MX960. 

Hope this helps. Your tunnel should work once you create this association. 

Kind regards,
Truman
