Hi @PD-Dell,

This is normal when you are configuring both active-active as both switches are doing L3 routing. I've read roughly through some guide, it stated that this will cause Split-Brain scenario which may lead to your ARP table displaying different entries. I'm attaching the VLT L3 architecture reference guide: https://dell.to/3XEkbnU

Also, a small explanatory of VLT Split-Brain scenario, page 14: https://dell.to/3XzNsQE

Hi,

i have doubt about state sync between switches , in the syncing IP address ( arp table will sync ) between switches ?

normally in the cisco VPC , aruba VSX both arp table normally same .

is there is command available to debug state packet between VLT switches ?

Hi, I'm not aware of a specific command to debug state packets between VLT switches. I saw debug ip packets cmd in reference guide for S5048F https://dell.to/3jUMpgE

I checked from here, if I didn't miss it, please take a look. https://dell.to/3YP2UJI

Hi,

I disabled Layer3 interface ( VLAN ) and enabled the interface . after that i can see that both switch having same number of AP entry .

but after ARP Timeout in sw2 arp entry is missing .

in the configuration gratuitous arp enabled ,arp learn-enable .

the arp entry missing in VRRP backup router is there is command available in VRRP configuration to sync arp table between master and backup

Hi @PD-Dell,

Are you referring to VLT unicast routing? https://dell.to/41xRzAa.

Perhaps, I may suggest that if the configurations are not as expected to be running, a support case need to be created by calling the support line. It would be best to check the switch's configurations and your network needs.
