Dual Internet T1 help

[dhouser]

Can anyone point me in the right direction. I need to add a second Internet T1 line to my company. How can I bundle these two T1's on one router so they can both share the load without doing BGP?.

The easiest way is to add two default routes on your router (one per T1) and on each serial interface add the command "no ip route-cache" -> this enables per-packet load balancing. You will also need to ask you ISP enable per-packet load-balancing on their end also and to add two routes for your network block over each T1.

e.g.

ip route 0.0.0.0 0.0.0.0 x.x.x.x (T1 #1)

ip route 0.0.0.0 0.0.0.0 y.y.y.y (T1 #2)

int s0

no ip route-cache

int s1

no ip route-cache

Alternately the command ip load-sharing per-packet

does the same thing as no ip route-cache.

You can also use MultiLink PPP to create a single virtual link out of several links, the two T1's in your case. This is only possible if both your T1's terminate at the same remote router (which first requires that they go to the same ISP). Both you and your ISP then configure a MultiLink PPP bundle.
