I have a Centro Office Router with Redunant links. If I want that Remote Offices have logical redundancy, should I ask my service provider to give two VLANs, so I can configure subinterfaces and route through EIGRP or OSPF?

any comment will be highly aprreciate

If the redundancy is for the attachment VC then you need to have physical redundancy of the links.

Logical redundancy wont help or is not required as you service providers core is anyway redundant to take care of the Circuit through the core. Only vulnerable area is the

UPE-CPE link, where you need redundant physical connections.

Hope I understood your query right, and replied accordingly.

Yes you're right...

Now, if I have redundant links on the central site...but remote sites have not redundant links, how can I tell the remote site, that if one link (on Central site) fails, to take the other link...
