[j-nsp] ipv6 routing

Mon Apr 5 02:32:37 EDT 2010

Hi Antonio,

yes, interface ge-0/0/0 is only configure for ospf3 and interface fe-0/1/0
is configued for dual-stack.

Here, I have listed the required configuation as you have asked.

scenario
 Cisco-rtr ------------------  ge-0/0/0 (M10i) fe-0/1/0 -----------------
Cisco-rtr
                     ospf3                               dual-stack
            ospf2 and ospf3

M10i config

show configuration protocols ospf
preference 110;
area 0.0.0.10 {
    interface lo0.0 {
        passive;
    }
    interface fe-0/1/0.0;
    interface fxp0.0 {
        disable;
    }
    interface fe-0/1/1.0 {
        passive;
    }
    interface fe-0/1/2.0 {
        passive;
    }
    interface fe-0/3/0.0 {
        passive;
    }
}

show configuration protocols ospf3
preference 110;
area 0.0.0.10 {
    interface ge-0/0/0.0;
    interface lo0.0 {
        passive;
    }
    interface fe-0/3/1.0 {
        passive;
    }
    interface fe-0/1/0.0;

Have a query that is, why even the static route didn't worked on the box?

Thank you,
