I have a central central with connectivity over IPLC circuits to two other office locatoins.
Location Y : Has a 5 E1 links to CO & is connected to Location X over 2 6Mbps MAN link. EIGRP is the routing protocol in use.
Location X : It has two routers, 4 E1 links on each router connecting to CO. EIGRP in use.
CO : Has connectivity to other location on MPLS - EIGRP & BGP are in use on this router at CO
Now, we have acquired a new link - POint to point -1DS3 on Router1 in Location X connected to CO. What should be the routing protocol that can be used? I need to have the DS3 link as the primary link & the 8 E1 links to be as backup.
If I configure EIGRP on the link, All the traffic via location Y to CO will traverse like : Location Y -- via MAN links --> Loaction X -- via DS3 --> CO.
I do not want this to happen.
How do I acheive this ?
What would happen if I configure BGP on the DS3 link ? This way, it'll take care of my 1st requirement, i.e, All the traffic would get routed via DS3 & the 8 E1 links will be in use only when the DS3 goes down. Is that right?
