Hi, Back in 2003 I failed miserably at configuring two 7206 VXR so that their FE interfaces could be connected to a VLAN switch, running MPLS in one VLAN and non-MPLS in other VLANs.
Basically I'd like to have int fa0/0.2 description MPLS VLAN for my routers encapsulation dot1Q 2 ip address A.X 255.255.255.248 tag-switching ip int fa0/0.3 description VLAN for my servers encapsulation dot1Q 3 ip address B.Y 255.255.255.240 int fa0/0.4 description VLAN for client-controlled servers encapsulation dot1Q 4 ip address C.Z 255.255.255.0 etc. This means that I could connect an incoming FE running pure MPLS over Ethernet to a 3550 switch (switchport access vlan 2) and from there on to two 7206 G1 on trunked interfaces, instead of having to do as I've done until now: dedicate one interface per router and a switch to MPLS, and run VLAN on the other interfaces. On ATM interfaces I can do this with no problem. On ethernet interfaces I never managed to do this, and I never managed to understand why. In hindsight it could have been the switch... Now when planning a bigger network the separation between my MPLS network and my VLAN network is becoming a burden. Should I be able to do this or is there some conflict between MPLS tags and VLAN tags on the same packet ? I need to know so I can decide what equipment to buy.
