[nsp] Interoperability between Juniper and Cisco on MPLS Martini

[Sergey V. Artjushkin]

Hi

> I am trying to get a l2circuit working between a M40 and 7507.

I have tested AToM between M5 and 7509:

Juniper:
interfaces {
    fe-0/0/1 {
        vlan-tagging;
        unit 0 {
            vlan-id 616;
            family inet {
                address 10.100.100.2/24;
            }
            family mpls;
        }
    }
    fe-0/0/2 {
        vlan-tagging;
        mtu 1500;
        encapsulation vlan-ccc;
        }
        unit 1 {
            encapsulation vlan-ccc;
            vlan-id 625;
        }
routing-options {
    static {
        route 192.168.0.1/32 next-hop 10.100.100.1;
    }
    router-id 192.168.0.2;
}
protocols {
    mpls {
        interface fe-0/0/1.0;
    }
    ldp {
        transport-address loopback;
        interface fe-0/0/1.0;
        interface lo0.0;
    }
    l2circuit {
        traceoptions {
            file l2c.trace;
            flag all detail;
        }
        neighbor 192.168.0.1 {
            interface fe-0/0/2.1 {
                virtual-circuit-id 1;
            }
        }
    }
}

Cisco:
tag-switching tdp router-id Loopback0
!
interface Loopback0
 ip address 192.168.0.1 255.255.255.255
!
interface GigabitEthernet0/0/0.625
 encapsulation dot1Q 625
 no ip directed-broadcast
 no cdp enable
 mpls l2transport route 192.168.0.2 1 
!
interface GigabitEthernet0/0/0.846
 encapsulation dot1Q 846
 ip address 10.100.100.1 255.255.255.252
 no ip directed-broadcast
 mpls label protocol ldp
 tag-switching ip
!
ip route 192.168.0.2 255.255.255.255 10.100.100.2

Everything is working ok. As I remember, there was some troubles with
rewriting VLAN tag and MTU (must be the same on both ends).
Also I have tested HDLC over MPLS, and it is also working well.

Try to use the same VLAN on 7507 and M40.
