[j-nsp] L2circuit between Juniper and Cisco

[Ioan Branet]

Hello group,



I am traying to configrure a L2circuit between an MX and a 7600 as PEs
(ethernet-vlan mode).

The problem is that the ping between CE1 and CE2 works only when I use the
same vlan-ids on both PEs.

If I use different vlans ID , on Juniper side CE wont learn ARP .

I use ccc encapsulation (should I use tcc instead ? -I did not find a
relevant example)

The l2circuit is up but I cant ping between CE1 and CE2

If I use tcc should I configure also proxy and remote fields ?

I do not know what are the CE1 and CE2 customers addresses.



Here is my config:



 ge-2/0/4

 flexible-vlan-tagging;
        mtu 9000;
        encapsulation flexible-ethernet-services;

unit 614 {

 encapsulation vlan-ccc;
            vlan-id 614;

protocols

l2circuit {
        neighbor 172.25.224.1 {
            interface ge-2/0/4.614 {
                virtual-circuit-id 4000080;
                encapsulation-type ethernet-vlan
                no-control-word;
