Nexus 3524 - does it support full EIGRP? Does EIGRP stub work?

[kbyrd]

I am installing a Nexus 3524 with the base license. I'm trying to do EIGRP stub with an IOS Catalyst 6506E. Both see each other as peers. The Nexus 3524 sees the Catalyst routes but the Catalyst does not see any Nexus 3524 connected VLANs. The Nexus 3524 replaced a 3750G which worked with no problem.

I am running system:    version 6.0(2)A6(5).

Relevant configurations:

Also, does the Nexus 3524 actually support full EIGRP?

Look for table 8.

Could this be right?

I'm not familiar with Nexus but I took a look at this guide:

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/5_x/nx-os/unicast/configuration/guide/l3_cli_nxos/l3_eigrp.html#wp1062713

It looks to me like you need something like:

router eigrp CCPS
  autonomous-system 10
  address-family ipv4 unicast
    stub direct redistributed

Note it also says you need the below on the core router that connects to the stub:

eigrp stub redistributed

Philip, see my comment above. I had to put the ip router eigrp processname command on each VLAN interface I wanted to advertise to the neighbor.

I'm still trying to determine if this is specific to the NEXUS 3524 platform. It is relatively new and I found one other bug related to vpc in this version of code. Maybe this is a bug as well.

[Philip D'Ath]

It says it only supports EIGRP stub.

Table 8 Feature-Based Licenses for the Cisco Nexus 3500 Series

Layer 3 Base Services Package LAN_BASE_SERVICES_PKG

N3548-BAS1K9

Static routing RIPv2 EIGRP stub OSPFv2 (limited routes) PIMv2 (sparse mode)

Philip, I open a TAC case on this issue. I should have been more clear on the problem. The neighbor does not see any of the VLAN interfaces.

I don't know if this is a workaround, if it's required, if STUB demands it, or it is something related to running/configuring Layer 3 on a Nexus 3524, but TAC said I had to put the command:

ip router eigrp processname

on each VLAN interface that I wanted to advertise to the neighbor.

I thought instead that the   stub direct redistributed command would have done it.

The workaround worked.

Regarding the license, the TAC engineer said that the Nexus Cisco Business Unit said that table was in error and that the Enterprise License would give m full EIGRP. She is going to confirm it with the BU.

Thanks for your comments.
