Need assistance in EIGRP Leak Maps

[Vinayaka Raman]

I tried to implement eigrp leak-maps and did not work ..need your help

route-map leak permit 10

I checked on the hub router and could not find the specific routes...

HUB#show ip eigrp topology  | b 10.60.4.0

        via 100.140.50.84 (58112/55552), GigabitEthernet0/0
        via 10.13.0.212 (1711616/28160), Tunnel2

Did you see hits in 'sh access-lists 10'. To me, the config looks good for a leak to occur. Can you post the dmvpn hub tunnel's interface config and EIGRP config on the hub. Are we learning 10.60.4.0/26 on the hub via any other protocol?

Please supply the output of "show ip eigrp topo 10.60.4.0/26" on the spoke router.

Thanks for checking..this morning i re-implemented and it started working..

After applyig leak, i could see /26 along with /22..../26 is an external route because we have another routing source advertising the same prefix and an admin distance tweked on hub to prefer external over internal..

HUB#show ip route | i 10[.]60[.]4
D       10.60.48.0/26 [210/1709312] via 10.13.0.234, 08:05:54, Tunnel2
D EX    10.60.40.0/22 [171/58112] via 100.140.50.84, 1w4d, GigabitEthernet0/0
D       10.60.4.0/26 [210/1711616] via 10.13.0.212, 00:01:19, Tunnel2
D EX    10.60.4.0/22

After removing the leak-map

HUB#show ip route | i 10[.]60[.]4
D       10.60.48.0/26 [210/1709312] via 10.13.0.234, 08:06:07, Tunnel2
D EX    10.60.40.0/22 [171/58112] via 100.140.50.84, 1w4d, GigabitEthernet0/0
D EX    10.60.4.0/22
