Are you talking about LB to Arista GARP, or Arista to LB GARP?
GARP is active by default on EOS, they are sent every 30 seconds.
You can adjust the timer for when the GARPs are sent with the below command.
If you change from the default of 30 seconds to 0, then it disables GARP from being sent.
Can you please detail your scenario and configuration?
Some load-balancers don't manage GARP very well and need to use IP masquerading or longer GARP timing, because some LB don't failover well as the standby keeps sending frames, so the primary must keep sending GARP until its standby unit gets silent.
According to the documentation, by default Arista switches reject gratuitous ARP:
By default, Arista switch interfaces reject gratuitous ARP request packets. The arp gratuitous accept command configures an L3 interface to accept the gratuitous ARP request packets sent from a different device in the network and add their mappings to the ARP table. Gratuitous ARP can be configured on Ethernet interfaces, VLANs/SVI, or L3 port channels, but has no effect on L2 interfaces.
Here the scenario is 2 load balancers, sharing a virtual IP , and when there is fail over, the new active one sends a GARP, which is rejected by the switch. Just curious why the default behavior is to reject ?
I see, you are talking about the GARP from the LB to Arista.
