EIGRP Distribute List on Nexus

EIGRP Distribute List on Nexus with Route-maps

HI,  I was wondering if anyone has done this successfully, I'm trying to  create a route-map for an EIGRP Distribute list on a N7K, the goal is to  not advertise a 10.0.0.0/8 and 172.31.30.20/32 networks out a link to a  remote site while permitting all other traffic to the internet  (default). I configured the ACL/route-maps below and applied them  outbound on the N7K interface but no subnets at all are being received  on the remote site router, any help is appreciated.

ip access-list DENY_10.0.0.0

  10 permit ip any 10.244.244.20/30 <<--WAN interface network

   20 deny ip any 10.0.0.0/8

   25 deny ip any 172.31.30.20/32

   30 permit ip any any

route-map BLOCK_10.0.0.0 permit 10

  match ip address DENY_10.0.0.0

interface Ethernet1/3

ip distribute-list eigrp 1 route-map BLOCK_10.0.0.0 out

EIGRP Distribute List on Nexus

Hi Bravo

Try the same with prefix lists.. it will work.. i had issues with route-map too, but prefix lists works great.

interface Ethernet1/3

ip distribute-list eigrp 1 prefix-list BLOCK_10.0.0.0 out

ip prefix-list BLOCK_10.0.0.0 seq 5 permit 10.244.244.20/30

etc

How many networks do you want to advertise out ? If there are too many try summarizing the subnets....

Hope this helps..

infact with route-maps, try using prefix lists instead of ACL's.. that might work too !
