cisco 881 with dual ISP

[Brent Rockburn]

Hey guys,

Thought I'd throw this out here and see what I get back.

I have an office that will have a microwave connection and a DSL location at the same site. I've been asked if it's possible to ensure the data goes through the DSL and VOIP traffic goes over the microwave. Is this possible with a cisco 881?

If so can someone post config examples or point me to the proper docs?

Thanks,

Brent

Hello Brent,

PBR policy based routing is the tool you need to go beyond destination based routing.

on the lan interface you apply

ip policy route-map mypbr

route-map mypbr permit 10

match ip address voip

set ip next hop microwave:nexthop

have the preferred default route via DSL and access-list voip is a named extended ip acl that defines voip bearer channels (RTP and RTCP) and signalling flows (SIP or H.323 or SCCP ...)

Hope to help
