Can you send the output of "show mpls l2transport vc 100 detail" from the Cisco and "show mpls vll 100" (or some detailed output) from the Brocade?
If you want to support full 802.1q tagging between ports (Cisco-Gi4/48 <=> Brocade-Eth1/1), let me know. You will need to use VPLS, not VLL.

Subject: [f-nsp] l2 pseudowire with between ASNs
Hi all,
I have a situation in which I'd like to encapsulate packets coming in on an 802.1q sub int on a Cisco 7600 and drop them into a VLAN on a Brocade XMR. The two routers are in two different ASNs and do not have an IGP. The two routers are directly connected to each other and
only speak via eBGP. I've got the "send-label" on the cisco side
and "next-hop-mpls" on the brocade side. It appears that I have and
LDP session but I'm not seeing labels and the
vll/xconnect/vc/pseudowire isn't up. The interface e1/1 on the
brocade side is a trunked port going down to other distribution switches and eventually a server that sits in vlan 3000. I apologize for my ignorance here, still learning all the moving pieces.
Thoughts?
Thanks!
