---------- Catalyst 2950 (CE)---------------------
---------------------------
Dear All,
Above is my network diagram. Being an ISP, I am willing to give
Redundant VPLS to customer (creating and binding vsi/vpls to CE
connected interface on PE) with the topology shown .
If I don't run STP protection for the loop between PEs and non-mpls
Catalyst 2950 (CE) shown in figure, is there any mechanism in VPLS (like
mac-withdrawal.etc) that defines these two arms of Cisco2950 to be
primary and secondary link thereby keeping one of the port of 2950
Catalyst in down state protecting the loop. And automatic switch over
for link failure.
Regards,
Khara Nanda Luitel.
