I want to design and implement load balancing between two wan links connected from a branch router to HQ router. The two WAN links ( W1 and W2) are connected to two different ISPs. W2 has twice the speed of W1. Routing protocol used is BGP. See diag for more info.
The two routers are Cisco.
1. Make use of all WAN links. When both links are up, networks 192.168.20.0/24 and 192.168.30.0/24 must use W2 and network 192.168.10.0/24 must use W1
2. When all only one link is up all networks must use that link. So it is kind of a backup link for the other network(s)
Any help much appreciated.
