Nexus: multiple ip distribute-list eigrp statements allowed ?

eric.thomas · ‎02-03-2014

Hi,

I need to clarify if Nexus 7K (NX-Os 6.1(3) ) supports multiple "ip distribute-list eigrp" statements in interface configuration.

Currently, there is already one statement to only allow default GW (0.0.0.0) routing information be sent.

I need to allow a few more specific routes to be shared with the facing device.

Can i have several distribute-list statements on the same interface ?

Or it it mandatory to handle this at the ip prefix-list level with multiple allow/deny rules.

I'm in a situation where i want to ammend the configuration without modifying existing objects or have to removed those who turned unused.

According to Cisco general EIGRP documentation, multiple seems to be accepted.

However, GNS3 simulator with a 7200VXR show that the new statement replaces the former one !

Moreover, Nexus logic is often different and i didn't capture any clear statement for this in Nexus specific documentation.

Needless to says that I have no test plateforme and no possibility to test that for the moment.

If someone can confirm it's supported, i would appreciate.

Thx

Hi,

I don't have a setup where I can try to see if this actually has the effect you're after, but you can certainly apply more than one distribute-list to an interface.

N7K-2(config-if)# ip distribute-list eigrp DIST_LIST route-map FRED out

N7K-2(config-if)# ip distribute-list eigrp DIST_LIST1 route-map FRED1 out

N7K-2(config-if)# ip distribute-list eigrp DIST_LIST2 route-map FRED2 out

N7K-2(config-if)# sh run int eth3/1

!Command: show running-config interface Ethernet3/1

!Time: Mon Feb 3 23:04:01 2014

version 5.2(1)

interface Ethernet3/1

ip address 1.1.1.1/24

ip distribute-list eigrp DIST_LIST route-map FRED out

ip distribute-list eigrp DIST_LIST1 route-map FRED1 out

ip distribute-list eigrp DIST_LIST2 route-map FRED2 out

no shutdown

N7K-2(config-if)#

Regards

Hi,

I'm using ip prefix-list, not route-map as in your example, but it should make no difference regarding my question.

Looks good to me.

I'll leave the topic open for a few days, just in case someone would have add some interesting comment to add.

thank you
