HSRP flap

Hi

 

We are facing HSRP flap in between x-connect of router , Physical Leg is passed via Switch & from switch side STP convergence & CPU utilization is fine in Switch

 

We are using below OS & ASR version.

System image file is "bootflash:asr1000rp1-adventerprisek9.03.01.03.S.150-1.S3.bin"
cisco ASR1002 (2RU) processor with 1717348K/6147K bytes of memory.
 

 

HSRP config

 

Router 1

interface GigabitEthernet0/0/3.870

no ip redirects

no ip unreachables

no ip proxy-arp

ip flow ingress

ip flow egress

standby 0 ip ******

standby 0 timers msec 200 msec 750

standby 0 priority 105

standby 0 preempt delay minimum 600 reload 600

end

 

Router 2

interface GigabitEthernet0/0/3.870

no ip redirects

no ip unreachables

no ip proxy-arp

ip flow ingress

ip flow egress

standby 0 ip IP address

standby 0 timers msec 200 msec 750

standby 0 preempt delay minimum 600 reload 600

 

Pls confirm whether this HSRP timer / OS version / ASR code is suceptible of any Bug behaviour

Don't exactly know what kind of business is this involved but I find the timers defined very aggressive.

I would try 500 msec with 1200 and also check any interface of any kind of error.

Hi Agree we are using

Hi

 

Agree we are using agressive timer, but same kind of setup is running in all location but in only 1 location we are facing this issue

Switch CPU,memory is fine & STP convergence is also fine for the problematic vlan

Hi,

 

 I would agreed with the previous comment, the timers are very low and if for some reason the hello is missed you may see the flap. I will also check the CPU utilization and the physical interface for any drops or input/CRC errors.
