Seperating routes with 2 DSL lines into 2811 1

[vdalehubbard]

I have two DSL lines coming into a 2811 router. Due to helping out with bandwidth, I need to seperate groups of internel IP addresses and assign them to different gateways (DSL lines). I want to ask what commands I need to use to do this. Here is my configuration on the router:

!version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!

line vty 0 4

!

!
end


I have the feeling it has to do with the ip route commands and changing them to reflect my internal ip ranges to what route I want. Any help is appricated.

You have to use policy-based routing:

!
route-map DSL permit 10
match ip address 101
set ip next-hop a.b.c.d
route-map DSL permit 20
match ip address 102
set ip next-hop e.f.g.h
!
interface FastEthernet0/1
ip policy route-map DSL
!
ip access-list standard 101
permit host 192.168.1.100
permit host 192.168.1.101
permit host 192.168.1.102
!
ip access-list standard 102
permit host 192.168.1.200
permit host 192.168.1.201
permit host 192.168.1.202
!

In this case for all traffic from the source IP addresses 192.168.1.100-102, it will use the next-hop a.b.c.d. And for source 192.168.1.200-202, it will use e.f.g.h.
