Opened: Nov 24, 2020
Severity: 3-Major


Gratuitous ARP (GARP) messages are dropped at the time of sending GARP because the number of links up in the trunk is 0 (which returns "error 18" ... ERR_NOT_FOUND)


Neighboring device arp table is not updated about the BIG-IP interface status, because no gratuitous ARP message is sent out.


-- Two BIG-IP systems with switchless configuration. -- Bring down and up the interfaces at the same time in the trunk.
