A method implementing dynamic next-hop routing at a network device is disclosed. The network device contains a routing information base (RIB) and a forwarding information base (FIB). The method starts with receiving a request to create a dynamic next-hop type using a next-hop schema. The dynamic next-hop type is for a prefix associated with an application. The next-hop schema includes a set of functions and a set of fields associated with the set of functions. The dynamic next-hop type is created using the next-hop schema at the RIB, where the set of fields associated with the set of functions of the dynamic next-hop type is processed. The created dynamic next-hop type is then downloaded to the FIB, where the set of functions of the dynamic next-hop type is processed. Afterward, an identifier associated with the dynamic next-hop type for the prefix associated with the application is returned.

Method and system of dynamic next-hop routing

A method is implemented by a network device for a fast traffic recovery process for the virtual redundant router protocol (VRRP), where improved speed in a switchover from a master VRRP router to a backup VRRP router is obtained by synchronizing an address resolution protocol (ARP) cache between the master VRRP router and the backup VRRP router such that after the switchover the backup VRRP router functions as a new master VRRP router and does not need to relearn media access control (MAC) address to Internet Protocol (IP) mappings of hosts using the new master VRRP as a gateway. The process involves receiving an ARP entry on an interface of the network device and checking whether the network device is configured as the master VRRP router. The process then sends a gratuitous ARP message to the backup VRRP router in response to the network device being the master VRRP router.
