Description
This is a regression fix for problem introduced by patch 11069846.
The change in this patch (patch 13440962) fixes a problem with 4 extra
bytes in the GARP message and removes an extra unicast GARP packet to
the router.
Rediscovery Notes:
After upgrading to 11.2.0.3, after vip failover, the ip address is
not pingable from a different subnet on Linux.
(This problem is seen only on Linux)
Workaround
After vip failover, run command
/sbin/arping -U -c 3 -I <public NIC for vip> <vip ip address>
to update the ARP table of router.
