What does this mean on a 3640 router?

//

Could someone please tell me what these lines do on our Cisco 3640 router?
We have 2 WAN interfaces, one goes to Savvis and the other goes to UUNET.

Looks like it sets it so that any traffic headed to 0.0.0.0-127.255.255.255 prefers your Savvis connection, while any traffic headed for 128.0.0.0-255.255.255.255 prefers your UUNet connection. Kind of an odd way to do load balancing, but it does create some load sharing and fail-over ... I'd use BGP over that config any day, though. $.02

dual hsrp groups for load sharing and fail over would be much better

and randall: it's doing load sharing, not balancing

It looks like somebody doesn't know BGP.

-edit- what I'm trying to say is that part of the config is meaningless unless we see the "router bgp" section of the config.
