Optimising 2 WAN connections ?

tonycarr · ‎03-21-2002

A question that has been asked many times before ;-

If I had two remote sites A & B. There are two WAN serial conenctions (10Mbps)between each site. Each terminating on its own router.

Site A Site B

----- wan -----

-|--- | R1A |....................| R1B |----|-

| ----- ----- |

Eth | |Eth

| ----- wan ----- |

-|--- | R2A |....................| R2B |----|-

----- -----

What is the best way to utilise all WAN bandwidths (2 x 10Mbps). I dont really what to use 2 HSRP groups at each site, as this would involve modifing host default gateways.

Is Policy routing the only other option I have ?

I havent tested this but I think you could put 2 static routes in R1B for example that points to R2B and R1A with the same admin distance and this should load balance over the two routers. You would ofcourse have to do this at the other side of the link. Bit more involved than this but I hope this is clear.
