Routing

Hi All,

Just a quick question.  is there a way to create an ipv6 over ipv4 tunnel without the use of an AS/tunnel service PIC?

Hi Cyke,

Not that I'm aware of.  All tunneling in JUNOS requires a Tunnel/AS PIC or AS Module in the M7i.  The one exception is the J series, which is able to do tunneling without any extra hardware, although not at anything like the scale of the M series and T series.

I'm a little confused as to how this works on the MX series.  The way I understand it, you can allocate one of the forwarding engines on a DPC card for tunneling services.  In my case I have an ipip tunnel built to Hurricane Electric in order to play with ipv6.  We can successfully advertise our v6 subnets over this link and I can reach any of the ipv6 interfaces from outside as long as those interfaces physically exist on the MX with the tunnel.  However, I cannot route traffic from another MX outside even though all of the internal v6 routing seems to be fine.  I guess my questions are:

1. It looks like this is the way to creat a tunnel interface:

[edit chassis]

    fpc 4{

         pic 3 {

              tunnel-services {

                    bandwidth  10g

So, on my MX480 I have a 4 port 10G blade in slot 4 and I have a vacant interface to use (3).  Can I still use the other 3 10G interfaces for ethernet transport?  That's not entirely clear to me.

2.How is the newly created tunnel interface designated?
