Hi All,

I am not a router guy but am in need of some quick assistance. We
have a Cisco 3640 router, with one LAN interface and one Fast Ethernet
WAN interface. We currently have two small net blocks on one
circuit. We are migrating to a new circuit with a completely
different net block and will be adding a second WAN interface during
the cutover. We will need the two WAN interfaces up while we migrate
servers over to the new circuit / new IP block so this is not a BGP
scenario.

My question is this, how do we configure our router's interfaces and
default routes to point to the correct associated interface? Here is
our current config.


interface Ethernet0/0
ip address 66.239.93.194 255.255.255.252
full-duplex
no mop enabled
!
interface Ethernet0/1
bandwidth 10000
ip address 67.106.113.1 255.255.255.128 secondary
ip address 205.158.167.129 255.255.255.224
full-duplex
no mop enabled
!
no ip http server
no ip http secure-server
ip route 0.0.0.0 0.0.0.0 66.239.93.193


Any help is greatly appreciated

Use policy routing, so that traffic is sent to the appropriate default
route depending on the source address.
