Tag :: Synchronization

Each ARP/ND packet into a switch may generate an update for the switch ARP/Neighbor table and this update may need to be synchronized with the MLAG peer when VXLAN is configured. Prior to this feature, these updates (on a VXLAN setup) are synchronized by sending an UDP packet (one packet per update) containing the IP/MAC/VLAN information from the MLAG peer where the ARP/ND packet is received to the other MLAG peer. 

LDP End of LIB is a signaling enhancement defined in RFC 5919 to allow an LDP speaker to notify a neighbor when it has

NAT peer state synchronization feature provides redundancy and resiliency for dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. The main motivation is that since the NAT state is shared between two switches, the failure of one switch can be tolerated since the other switch will retain the translations.
