HSRP Failover on Nexus 7k for no reason

We had major Network outage on April 9 and 10th due to HSRP failover on our distribution layer Nexus 7k switches. Few Nutanix hosts were unable to reach their gateway and as a result multiple applications that hosted these Nutanix environment were affected. Any idea what could be the reason of this behavior?

Hello,

 

--> VLAN 599 is spanned between our datacenter at San Antonio and DR at Scottsdale with OTV. The gateway for VLAN 599 is .1 in San Antonio but it is .254 in DR. This is by design.

 

How is San Antonio connected to your two Nexus switches ? Does it use the same HSRP group ?

Yes, we are using HSRP.

 

AM-US-SAT_6-DD-35-BDRLFSW01# sh running-config hsrp all | begin 599
interface Vlan599
no hsrp bfd
hsrp version 2
hsrp delay minimum 0 reload 0
no hsrp use-bia
no hsrp mac-refresh
hsrp 599
authentication XXXX
mac-address 0000.0C9F.F257
preempt delay minimum 0 reload 0 sync 0
priority 130
timers 3 10
ip 172.28.219.1

 

AM-US-SAT_6-GD-35-BDRLFSW02# sh run hsrp | begin 599
interface Vlan599
hsrp version 2
hsrp 599
preempt
ip 172.28.219.1

 

AM-US-SCF_01-0726-35-BDRLFSW01# sh running-config hsrp | begin 599  (This is DR center)
interface Vlan599
hsrp version 2
hsrp 599
preempt
priority 120
ip 172.28.219.254

Are we missing authentication configuration on BDRLFSW02? To be honest, I feel some configuration is missing on BDRLFSW02 or miss configuration that has caused this issue. Please see below.

 

AM-US-SAT_6-DD-35-BDRLFSW01# sh hsrp group 599 brief
*:IPv6 group #:group belongs to a bundle
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Vlan599 599 130 P Active local 172.28.219.4 172.28.219.1 (conf)

 

AM-US-SAT_6-GD-35-BDRLFSW02# sh hsrp group 599 brief
*:IPv6 group #:group belongs to a bundle
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Vlan599 599 100 P Listen 172.28.219.2 172.28.219.4 172.28.219.1 (conf)

 

Above output says 172.28.219.2 is the active device and 172.28.219.4 is the stand by device. But when we did a SSH to 172.28.219.4, it is taking me to AM-US-SCF_01-0726-35-BDRLFSW01 which is at our disaster recovery datacenter.

 

AM-US-SCF_01-0726-35-BDRLFSW01# sh hsrp group 599 brief
*:IPv6 group #:group belongs to a bundle
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Vlan599 599 120 P Standby 172.28.219.2 local 172.28.219.254 (conf)

 

HSRP is in stand by state for VLAN599 in our DR center. But, this should be like this, our requirement is when AM-US-SAT_6-DD-35-BDRLFSW01 fails AM-US-SAT_6-DD-35-BDRLFSW02 should take over the traffic not AM-US-SCF_01-0726-35-BDRLFSW01 becuase the group address are different at San Antonio DC and Scottsdale DR. Please advise.

Your priority needs to be readjusted.  By default, priority is 100.  Higher priority determines the order of precedence.  

See link, https://www.cisco.com/c/en/us/support/docs/switches/nexus-7000-series-switches/113002-nexus-hsrp-00.html

  • BDRLFSW01 - keep "priority 130"
  • BDRLFSW02 - add "priority 120"
  • AM-US-SCF_01-0726-35-BDRLFSW01 - remove "priority 120"; add "priority 110"

You may want to remove HSRP authentication or add authentication on each HSRP members within the same group.

I can't say what cause your outage several weeks ago.  Do you recall any change that happened prior to the outage within the Nexus or outside network related?  Your company should have a configuration change manager who can tell you what work approved to perform that day.
