Thank you, Ole. Great that you put this in the context of point to point interfaces. But I think a fundamental issue remains -- one that Dave Barach would remind me of, although I hope I do not misrepresent his question. As I see it, one line card represents a router, and it has 2 point-to-point i

Krishna, I am almost certain that you want to stick with the VPP design, and that you do not have a valid case for a design change. Accept the fact that you have to add more VLANs/subnets to the PE router, when, in fact, you have more VLANs/subnets in your system. It is possible to do what you ar

But Chris, I believe that wireless access point is using bridging -- not the same thing. You probably can verify that by local log in to an ASUS router or something else that uses Linux underneath, and double check me, using ifconfig or ip commands. Burt -=-=-=-=-=-=-=-=-=-=-=- Links: You receive
