[j-nsp] QinQ between Cisco/Juniper with layer2-tunneling and VPLS
Hi, has anyone working QinQ between Cisco and Juniper running over VPLS and with working layer2-tunneling? We have a setup like this: EX4200 -- QinQ -- MX === VPLS === MX -- QinQ -- Cisco We see that on both ends of the QinQ tunnel CTP/STP/LLDP Pakets are encapsulated but on the other side nothing gets decapsulated.

Re: [j-nsp] QinQ between Cisco/Juniper with layer2-tunneling and VPLS
1. EX4200 - I assume this following:
ethernet-switching-options {
dot1q-tunneling {
ether-type 0x8100;
}
}
vlans {
My-QinQ-VLAN {
vlan-id 1000;
dot1q-tunneling {
layer2-protocol-tunneling {
all;
}
}
}
}
2. Note that the EX4200's re-write the MAC Address when using QinQ (i.e. STP
MAC 01:80:c2:00:00:00 becomes PVST+ MAC 01:00:0c:cc:cc:cd, for example). Ensure
you are un-translating the MAC address at the far end MX or at the Cisco; else
you end up with a regular RSTP Packet with the wrong Destination MAC Address.
3. Alternatively, POP the outer Tag on Ingress at the MX; and do the MAC
destination re-write there (i.e. change it back to normal) before shoving it
into the VPLS.
