We have a requirement to provide L2 Ethernet "VPNs" to our clients(Historically, we have only provided L3 MPLS VPNS) - Our clients ethernet Tails are presented to us over GBIC Trunks from our various Ethernet Providers....the providers control the VLAN Id presented to us for each client tail.
Is there anyway to "rewrite" or "map" multiple vlan id's to one?(Without bringing the vlans up into our Routers, and adding each dot1q Int. into a bridge group?)
Client A has 4 ethernet tails presented to us from 2 providers(Both providers terminate on the one Switch):
Provider 1 presents VLAN 501 and VLAN 502
Provider 2 presents VLAN 601 and VLAN 602
Is there any way to rewrite the 4 vlans to VLAN 50, so that all 4 tails are in a flat L2 network(Client has full control over IP addressing) - If so, at a minimum, what Switch would be required?(3750?)
VPLS would be the most obvious solution, but we currently only have 7200's at the core, connected to 2950's(L2 Ethernet has not been a focus until now ;) )
All suggestions are greatly appreciated.
