Hi all,
to attach an interface to a vfi I have seen two kind of possible solution:
!
L2 vfi <name> manual
Vpn id <VPNid>
bridge-domain <bridge-domain id>
Neighbor <Remote-PE>
!
interface fastethernetx/y
bridge-domain < bridge-domain id>
or
interface fastethernetx/y
xconnect vfi <name>
What is the difference between the command bridge-domain o xconnect? When I must use one or the other?
Thanks in advance

hi! I am not entirely sure about it but this is my best shot...
X-connect would be used to establish a pseudo-wire (point-to-point) for an EPL service like EoMPLS. That will just connect the 2 UNI together to the VC created by the X-connect command. In this case ther would be no mac table maintained for the VSI in the router.
Bridge domain can be used so that you create a seperate bridge domain ( like a virtual bridge) and add ports to that and connect it to remote PE so that you create a VPLS connection. The PE will maintain a seperate mac table for the VSI.
So thats what I think - PWE3 v/s VPLS..
Correct me if I am wrong.
Thanks....

Thanks for your support..but i think that there is something not clear yet.
In the following link:
you can find a VPLS configuration with xconnect...
So we need to investigate....

Hi,
i tried once that bridge-domain has been used in GSR12000 code (the one i know), the rest like in 7600 newer code (SX or SRA), you will find it as "xconnect vfi
