HSRP on nexus 5000

Is the routing module needed for HSRP to operate?

I do not have such module but I was able to configure the feature but it seems they do not communicate both 5Ks remain active and the virtual IP is not reachable.

The VLAN is allowed over the vPC pee-link

Here's my config

N5K-SW1# sh runn int vlan 999

!Command: show running-config interface Vlan999
!Time: Wed Jan  7 03:39:42 2009

interface Vlan999

HSRP on nexus 5000

Hi Maarten,

For HSRP or any L3 protocol to run you will need the L3 daughter card.  The software is still there in NX-OS so it itself is not depending on it.  You'll see similar issue if you were to run EIGRP or some other routing protocol.

I'd think an enhancment could be added that would allow you to configure this (say for prep for your l3 card) but alert you that it won't be functional.

If you have further questions about this, we can continue here.  Also note you can open a case with the PDI Datacenter help desk here:

Hope that helps

Re: HSRP on nexus 5000

HI,Chad,I have an issue similar with Maarten's.Though I have a l3 routing card of 160G/S,I failed to make the HSRP successful.they do not communicate with each other for HSRP.Each thinks itself active and the virtual IP is not reachable.

Here is my config

version 5.1(3)N1(1a)

vrf context management

  ip route 0.0.0.0/0 192.168.150.2

vpc domain 1

  peer-keepalive destination 192.168.150.2

  peer-config-check-bypass

  delay restore 5

  peer-gateway

  auto-recovery

  ip arp synchronize

interface Vlan11

  no shutdown

  no ip redirects

  ip address 10.113.7.252/24

  hsrp 11

    preempt

    priority 110

    ip 10.113.7.254

interface mgmt0

  ip address 192.168.150.1/30

interface port-channel20

  switchport mode trunk

  spanning-tree port type network

  speed 10000

  vpc peer-link

I can not find what 's wrong with the configration,but the result is.......

N5K-core-1# sh hsrp group 11

Vlan11 - Group 11 (HSRP-V1) (IPv4)

  Local state is Active, priority 110 (Cfged 110), may preempt

    Forwarding threshold(for vPC), lower: 1 upper: 110

  Hellotime 3 sec, holdtime 10 sec

  Next hello sent in 0.373000 sec(s)

  Virtual IP address is 10.113.7.254 (Cfged)

  Active router is local

  Standby router is unknown

  Authentication text "cisco"

  Virtual mac address is 0000.0c07.ac0b (Default MAC)

  2 state changes, last state change 00:33:03

  IP redundancy name is hsrp-Vlan11-11 (default)

I think I would be crazy,my god.

HSRP on nexus 5000

Maarten, even though you see HSRP related configs on NX-OS, it is not available without an L3 daughter card and license on the 5K.

It is similar to seeing feature glbp on the 5K, but glbp not being available on the 5K. When NX-OS was written, it wasn't segregated keeping in mind 5K vs 7K unlike the IOS for say a 3750 switch vs a 3925 router.
