F5 Gratuitous-ARP issue when failover
Hi Last night we upgrade F5 v. 11.5.4 to v.12.1.3 when we failover from old unit v.11.5.4 to newly unit v.12.1.3, We experience some IP has more request timeout than the rest (we ping ip of each vs (~20 ip) when failover) From my understanding, F5 will send G-ARP to neighbour unit when it's active. Is it possible that G-ARP that sent is drop so those IP experience longer downtime due to still using old ARP? or Is it because neighbour unit not use some G-ARP from F5? or Is there any possibilities that make neighbour unit not learn new ARP as expect? Thank you
