I want to install another WIC and another T1 line into our 2811 routers so that we can have two T1 lines between our offices. We currently have one T1 line, but we have an application that consumes the bandwidth, so we would like to install a second T1 line to give the app its own T1 line. So we will add a second WIC to each 2811.
Now for the fun part. How would I setup the routing in the routers to accommodate this? We have two offices, NY & GA. NY uses a 192.168.110.0/24 subnet and GA uses a 192.168.120.0/24 subnet. The T1 line between the two offices is on a 10.1.2.0/24
Here is the sh ip route from NY router:
S 192.168.120.0/24 [1/0] via 10.1.2.2
C 192.168.110.0/24 is directly connected, FastEthernet0/1
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.1.2.0/24 is directly connected, Serial0/0/0
C 10.1.2.2/32 is directly connected, Serial0/0/0
C 192.168.0.0/24 is directly connected, FastEthernet0/0
S 192.168.1.0/24 [1/0] via 10.1.2.2
S* 0.0.0.0/0 [1/0] via 192.168.0.2
What we want to do is have the application, which resides at 192.168.110.12, to only use the new second WIC. So therefore, all traffic that comes from 110.12 will go to the second WIC down to GA to 192.168.120.4
and therefore, of course, vice versa. All traffic coming from 120.4 will go over the second WIC to 110.12
Thanks so much.
