EIGRP

Remote router with a T1 and frame relay to central office. EIGRP is running and the traffic is going over the T1. I want the remote site 10.221.x.x/16 to access one server 10.200.7.59 (central site) over the frame not the T1. Redistribute static is configured at both sites. When I put a static route at the remote site to use the frame the central site cannot get to the server (routing loop). What's the best way to do this?

Re: EIGRP

I wouldn't redistribute these 2 static routes into EIGRP. If you need to do this for other statics then add a route-map to redistribute command and filter only the static routes you want to be redistributed into EIGRP.

On the remote router, you can use a static host route:

IE: ip route 10.200.7.59 255.255.255.255 (frame relay next hop)

On the central site:

ip route 10.221.x.x 255.255.0.0 (frame relay next hop)

If the frame goes down, then the static routes will go away and the EIGRP ones will be used if the T1 is still up.

Re: EIGRP

If I put that static route in the central site all traffic will go through the frame to remote site. I used a distribute list to not advertise the 10.200.7.59 route at the remote site then added the static route and it did the trick:

ip route 10.200.7.59 255.255.255.255 ( frame route ) <<<<<< Added

distribute-list 40 out static <<<<<< Added

access-list 40 deny 10.200.7.59 <<<<< Added

access-list 40 permit any <<<<< Added

Re: EIGRP

Hi Erick

I found the route map idea a good option for only redistributing specific static IP routes, Icould do with something like this for my network, could you possibly show me a config example.

Re: EIGRP

Karl,

Something like this:

route-map statics perm 10

match ip address 1

router eigrp 101

redist static route-map statics metric 10

access-list 1 perm ip 10.10.10.0 0.0.0.255

access-list 1 perm ip 20.20.20.0 0.0.0.255

The above will only let static routes to 10.10.10.0/24 and 20.20.20.0/24 into EIGRP. All other statics will not be redistributed into EIGRP.
