We have a single router that is the last hop router before our firewall and the inside interface, E0, of that router is our default route.
Say E0 is 192.168.1.1, all of our internal routers have 'ip route 0.0.0.0 0.0.0.0 192.168.1.1' configed.
E0 of this router is connected to a switch and two distribution routers are also connected to that switch, and it is through these two distribution routers that all traffic flows from our internal network to the last hop router.
I'd like to get rid of the last hop router which would mean the two distribution routers would actually be the last hop before the firewall.
What is the best way to have a new default route with those two distribution routers? Could I use the L0 interface ip address in each router and distribute that into EIGRP as the default route in essence giving two default routes with the same metric? Would I need to give one a lower metric?
Any suggestion are appreciated.
For loadbalancing keep the metric same but it would still depend upon how other devices are connected to the distribution switches. The shortestr metric would be chosen
yes for redistributing only the default route you need to use the route-map
ip route 0.0.0.0 0.0.0.0
router eigrp 100
redistibute static route-map default metric 10000 10 255 1 1500
route-map default permit 10
match ip address 1
access-list 1 permit 0.0.0.0
