Hi all,
I have a routing question with regards to EIGRP. Our hd office is connecting to br office via EIGRP. one of my office network is 18.25.0.0/18. My br office network is 18.26.6.0/24. We recently installed a secondary link, I wanted to route the subnet 18.25.5.0/24 from hd office via the secondary link for destination 18.26.6.0/24. So as in Br office the route from 18.26.6.0/24 for 18.25.5.0/24 should be routed via secondary link. I have not enabled any routing on secondary link, and thinking of EIGRP for routing. How to achieve this.
on our wan router in hd office
router eigrp 1
redistribute static
ip route 18.25.0.0 255.255.124.0 172.16.10.13
On our Wan router in br office
router eigrp 1
redistribute static
ip route 18.26.6.0 255.255.255.0 10.152.48.1

It would be better to use PBR than EIGRP for acheiving this
With EIGRP all traffic to 18.26.6.0 or 18.26.5.0 will use the secondary link if configured but if you need a specific source destination conversation to flow through a particualr link, PBR would be the choice
at HD
access-list 100 permit ip 18.25.5.0 0.0.0.255 18.26.6.0 0.0.0.255
route-map test permit 10
match ip address 100
set ip next-hop
interface
ip policy route-map test
At Branch
access-list 100 permit ip 18.26.6.0 0.0.0.255 18.25.5.0 0.0.0.255
route-map test permit 10
match ip address 100
set ip next-hop
interface
ip policy route-map test

Hi Narayan,
Thanks for your quick response. This should definetely work.

If you actually want to loadshare the traffic, you can actually use Variance to do unequal cost load balancing.
Incase you have a specific requirement for routing these specific subnets, you can do so by static routing (with floating routes for redundancy).
