[j-nsp] Logical tunnel encapsulation

[Eric Van Tol]

Hi all,
Is frame-relay encapsulation not supported on the MX80 logical tunnel interfaces?  I'm on 10.4R8.5 and need to configure IPv6 on an lt- interface:

Interface on the default instance:

# show interfaces lt-0/0/10 
unit 1 {
    encapsulation frame-relay;
    dlci 128;
    peer-unit 1;
    family inet {
        address 192.168.209.201/30;
    }
    family inet6 {
        address 2001:db8::d1c9/64;
    }
}
Interface on my logical-system:

# show interfaces lt-0/0/10 
unit 1 {
    encapsulation frame-relay;
    dlci 128;
    peer-unit 0;
    family inet {
        address 192.168.209.202/30;
    }
    family inet6 {
        address 2001:db8::d1ca/64;
    }
}

Interface shows 'up' and no flags are set to indicate a problem.  However, pinging doesn't work and this shows up in my logs:

Also, this all works if I remove 'family inet6' and change encapsulation to 'ethernet'.

If frame-relay encapsulation isn't supported, how does one use IPv6 on the lt- interfaces?  

Thanks in advance,
