We have been switched onto an MPLS network (BT IP Clear ADSL MAX in the UK)
The ISP has specified the PE Router and given us a STATIC LOOPBACK ADDRESS for each site that we have.
We have enter this into our CE Router as the WAN address & the routers on each site can see each other via pings etc
How do we go about getting the LAN side of each router talking to the LAN side of the other routers?

1. Is this done via static routes?
2. Would RIP benefit us here?
3. Can we run vlans over the the MPLS network so that Vlan 3 on SITE A can talk directly to vlan 3 on SITE B

Our ISP has also set the static loopback address to 10.1.1.1/32 (SITE A) & 10.1.2.1/32 (SITE B) etc
If we wanted our LAN side on SITE A to be 10.1.1.0/24, do we have to change the WAN side to something other than 10.1.1.1/32 ie the WAN side has to be totally different subnet to the LAN side?

Any help would be appreciated here.
Thank you.

I think you must ask to your MPLS provider to annunce your private LAN of each site in the mpls cloud.
If you have a private mpls cloud you can implement by your self routing by staticroute or other dynamic routing protocol such as ospf.

I hope this help!

It sounds as if the service is using a layer 3 handoff with a 1500 MTU.

Static routes could be used to configure site-site paths. If using a dynamic protocol it is better to let RIP do exactly that (RIP). OSPF would be easy to configure if there are redundant paths.

Do they offer VPLS? If you had a layer 2 hand off with a slightly higher L2 MTU then VLANS would be easy.
