Hi,
I have to carry many few L2 circuits of same customer with a ME6524 as a uPE device. As SVI based EoMPLS is not possible on this device.
Can I do the following , (if yes, this solves the same purpose as SVI based EoMPLS).
I use vlan 200 for this customer & I assume MuxUNI support works well on Uplink port aswell. ( I know it works on Downlink port -- customer facing port)
int Gig 1
switchport mode access
Switchport access vlan 200
Int Gig 2
switchport mode access
Switchport access vlan 200
Int Gig 25
description << Uplink to MPLS cloud>>
mpls ip
ip address 1.1.1.1 255.255.255.0
Int Gig 25.200
encap dot1q 200
Xconnect 5.0.0.5 2000 encap mpls
Is it possible and any comment..Have anybody done this practically..
Thx,
gaurav

You can use port based EoMPLS on the ME6524
See example below..

Thx,
But I need to keep the VC ID of the PWs same ( as they belong to same VPLS domain & same customer ), as there are multiple cirucits coming to this uPE, the only way I can do it to make the switchports mode access , and map it with same vlan id ( 200 in this case ).. now to take the traffic into MPLS cloud , I can ( NOT SURE ! ) xconnect the Layer 2 dot1q Subinterface of the uplink . The dot1q vlan id needs to be same as the customer i.e 200 ( in this case )..
I need to check if this idea works or not..
Thx,

In the configuration example above, the VC ID is the same on both sides.
So in your design you should have
CE1 (gi1/0/1 trunk vlan 200) --Gi1/0 subint dot1 V200) PE1 (ME6524)--- Xconnect--MPLS--xconnect--PE2 (ME6524)--- Gi1/0 subint dot1 V200)- (gi1/0/1 trunk vlan 200) CE2.
Hope to help
