Load Balancing over WAN Links

Scenario:

- Two Sites

- Each site has two routers connecting both the sites

- At each site, Router 1 has two leased lines connected and Router 2 has one. Thereby making it three WAN links between the sites.

How can I achieve load balancing on the WAN links to ensure uniform link utilization. Only one destination exists for the communication between the sites. Packet sharing is a risky option. What is the safest way to load share on the WAN links in the given scenario.

Re: Load Balancing over WAN Links

Are you using a routing protocol?

No. We will be using static routes only.

Re: Load Balancing over WAN Links

I readup some materials. Please let me know if the following seems to be a good option

1) Use multilink PPP for aggregation of serial links on the routers across both the sites

2) Configure GLBP/HSRP on the inside ethernet interfaces on all the routers.

With #1, even utilization of the WAN links within the router shall be ensured. And with #2, the traffic hitting the router on the inside will be load balanced.

Please advise.
