wan link balance

[aviolindo]

its possible to balance several wan links. 2 situation, one if de link belong to the same ISP, 2 if the links belong to several ISP.

My question is, can we do that?

Hi,

You sure can do that, just make sure that you terminate your ipsec tunnels on a loopback interface.

Thanks,

I am also interested ; I have a main site connected to 10 remote using gre+ipsec; the isp is performing badly, so I want to add a second internet connection to the second serial interface and move some vpn's from "ispA" to the new isp.

Theorically this should be ok, but can you mention working similar design?

One way is if you are using BRI, then you can use multilink or bandwidth on demand technology (BOD). you can achieve this by giving

ppp multilink

dialer load-threshold load [outbound | inbound | either]

or if you have any primary link, then you may specify a back up link, saying if the load reaches some threshold, you can enable the second link.

the following site might be of help
