Multilink Question

[Pnun]

I have a T1 that plugs into a 1720 router. The 1720 is connected to a PIX. I plan on installing another WIC into the 1720 to utilize another ISP's service. Is there a way to configure the 1720 to see the two lines as one? If so, what is the config for that on the 1720? Will I have to make any config changes to the PIX?

Here is the current config for the serial (T1) interface on the 1720:

interface Serial0

ip address x.x.x.x 255.255.255.x

encapsulation frame-relay IETF

frame-relay interface-dlci 16

Thanks

If the 1720 has two T1s and both are configured with PPP encapsulation, then you can configure multilink and the router will treat both T1s as a single entity. However that presumes that both T1s go to the same destination and that does not fit your requirements.

Why do you want to treat the two lines as one? If they are going to different ISPs do you not need to treat them separately?

What is it that you are really trying to achieve?

Thanks for you response Rick.

I have a couple of reasons for wanting them to be treated as one line. First I thought that I could utilize the bandwidth from both connections for better transmission speeds. Second I thought for redundancy - if one connection fails the other will still be up.

Thanks,
