Missing route in EIGRP

zrunner626
Level 1
Level 1

Hoping someone can help...

I have a couple static routes in my data center switch, for traffic pointing to an ASA (site-to-site tunnel with another company.) The switch is redistributing the static routes into EIGRP. I see the routes in EIGRP on the switch, no problem there. I even see the routes in the routers at the data center (I have two, we are using iWAN - DMVPN, NHRP, EIGRP). but the branch routers are not seeing that route.

I have checked the route-maps/prefix-lists to make sure it is not being filtered on either the DC router or the branch router. 

Split-horizon is turned off.

Any other thoughts?

Hello,

I have a feeling that your summary addresses are causing the problem. Do you actually see the EIGRP neighbors on each side ?

Either way, try and take the two lines below out:

af-interface Tunnel11
summary-address 10.0.0.0 255.0.0.0 leak-map EIGRP-LEAK
summary-address 10.1x.0.0 255.255.128.0 leak-map EIGRP-LEAK

Hello,

post the configs of one of the branch routers and the DC router (that is, the router directly connected to the branch router)...

Hello,

I have a feeling that your summary addresses are causing the problem. Do you actually see the EIGRP neighbors on each side ?

Either way, try and take the two lines below out:

af-interface Tunnel11
summary-address 10.0.0.0 255.0.0.0 leak-map EIGRP-LEAK
summary-address 10.1x.0.0 255.255.128.0 leak-map EIGRP-LEAK

Yes, I see the Tunnel interfaces on each side. I'll find a time to remove those lines. 

Hello, 

you refer to two VRFs, INET on your DC router, and MPLS on your branch router. They are not in the configurations you posted ?

This got me thinking...

We wanted the summarization so I added those routes to the EIGRP leak-map and they showed up on the branch router.

Thanks for your help!

Hello

If you have next-hop self enabled then try disabling it

what Dmvpn phase are you using

Next-hop self is not enabled. Not sure on the dmvpn phase, I would guess 2.
