Nexus 9K Distribution List problem

[Cormac Champion]

Hi all,

I have a simple problem with a Distribution list.  I simply want to advertise 10.10.20.0/24 to an EIGRP neighbor on a 6509, in addition to advertising all of the connected routes.

So I have added the following

ip prefix-list SEND-TO-6500 seq 10 permit 10.10.20.0/24

!

route-map SEND-MAP-TO-6500 permit 10
match ip address prefix-list SEND-TO-6500
route-map SEND-MAP-TO-6500 permit 20

!

interface Vlan100
description ** N9K_to_6509_Link **
ip address 10.10.0.1/30
no ipv6 redirects
ip router eigrp 100
ip distribute-list eigrp 100 route-map SEND-MAP-TO-6500 out

All of the EIGRP networks are advertised but the 10.10.20.0/24 is not being advertised.  What have I missed please ?

Can you post the output of show ip route? We want to be sure that 10.10.20.0/24 is in the routing table.

It's there and in order to get it working for now, I have added a static route on the 6509, and it's working perfectly.

The reason as to why I needed to advertise the subnet was because it is in a VRF and it leaked from it's separate VRF into the Default VRF.

10.10.20.0/24, ubest/mbest: 4/0
*via 10.10.10.2, Vlan100, [170/51456], 06:15:43, eigrp-100, external, tag 100
*via 10.10.10.3, Vlan100, [170/51456], 06:15:43, eigrp-100, external, tag 100
*via 10.10.10.4, Vlan100, [170/51456], 06:15:43, eigrp-100, external, tag 100

Hi Rick,

Any further thoughts of what could be wrong to allow the distribution-list to work automatically ?

Having the static route on the 6500 is a work around which I would prefer to remove.

I believe that the key to this is your statement that the subnet is in a vrf. Could you provide some additional detail about your environment, especially the vrf specifications?
