BIG-IP Peer self local IP cannot be ping

Hi Expert, I have a big-ip in HA setting. But if I am in primary one, I cannot ping peer local self IP. I can ping primary local and floating IP.  https://my.f5.com/manage/s/article/K3475 I chec...

Hello

Sorry for late reply

They are in corrected vlan. However, the peer one cannot ping the gateway.

It seems this is network problem instead of BIG-IP problem

Hi SolarJeans , 

Try to add a static ARP entry in both Bigip boxes. 

First)

issue this command on tmsh : 
#show net vlan
and get the HA vlans MAC addresses on both devices.

Second ) 
Add a static ARP entry for both devices in each other. 
Follow this KB to do it : https://my.f5.com/manage/s/article/K16221

on brief , I want you to give up using dynamic arp to map IP & MAC , and using a static entry instead to define your issue is related to big ip interfaces , of one of your nodes can't resolve arp requests. 

Chack again and let me know
