Tag :: Refresh

Forced periodic ARP refresh adds support for a mechanism that allows forcing ARP/NDP refresh requests to be sent in periodic intervals independently of ARP/NDP entries' confirmed time in the kernel. By default, when a neighbor entry gets confirmed by various processes such as ARP synchronization between MLAG peers, an ARP refresh request is not sent for at least another duration of ARP aging timeout (or ND cache expiry time for the IPv6 case). This feature provides support for a configuration to force sending refresh requests at the configured ARP/ND aging timeout regardless of the last confirmed time.
