WARNING - n00b questions ahead!
I have set up a layer 2 VPN using VPLS, in a test environment. It functions, and works perfectly. It uses OSPF for routing.
Now I want to test a layer 3 VPN. Can I do something as simple as attach an IP Address to the tunnel? (I warned you it was a n00b question).
Or do I NEED BGP on the edges?
If I can implement it without using BPG, it would be handy.
If you are talking about L3VPN then you need BGP to carry vpnv4 routes.
But if you want simply routing over VPLS tunnel then yes you can add IP address to vpls add routes and use it for routing.
Damn.
Thanks.
n00b question part 2.
Does BGP need to be on all routers in-between? In the example here http://wiki.mikrotik.com/wiki/Manual:Layer-3_MPLS_VPN_example, BGP is on the middle router too. In my setup, there are 9 routers. And if it is needed on all routers, as this scales up, it surely gets annoying?
Another n00b question. Do I need a router on the customer premises? Or can it be connected directly to a computer? I know, weird question. I just dont have more routers, and dont really want to reduce my “internal” configuration.
No, you need BGP only on edge routers. But MPLS must be enabled on all routers.
