The FHRP allows a router on a LAN segment to automatically take over if other fails.

It is not compatible with version 1 HSRP. HSRP ( Hot Standby Router Protocol) is one of the most popular First Hop Redundancy Protocols (FHRP) made by Cisco. Local virtual MAC address is 01 (v1 default) Hello time 3 sec, hold time 10 sec. Version 2 of the protocol introduces stability, scalability and diagnostic improvements. Hot Standby Router Protocol (HSRP) is a Cisco proprietary protocol that allows several routers or. 0000.0C is the Cisco Vendor ID 07.AC is the HSRP ID XX is replaced by the HSRP Standby. The Virtual IP address 10.0.0.1 and virtual MAC-Address 00-10-0C-07-AC-0A are. HSRP v1 uses the virtual MAC address of 0000.0c07. Logical MAC address generated in the format:. If the link of the primary router goes down, the backup router will take over the primary functionality and thus retain connectivity to the gateway. HSRP or Hot Standby Router Protocol is a protocol defined by Cisco and now. This can be useful for dual branch routers each with a single link back to the gateway. HSRP has the ability to trigger a failover if one or more interfaces on the router go down. HSRP is not a routing protocol as it does not advertise IP routes or affect the routing table in any way. When the HSRP is configured on a network segment, it provides a virtual Media Access Control (MAC) address and an IP address that is shared among routers in a groupof routers that is running HSRP. In the virtual MAC address, Xs represent the group ID in hex. If the primary router should fail, the router with the next-highest priority would take over the gateway IP address and answer ARP requests with the same MAC address, thus achieving transparent default gateway failover.

The primary router with the highest configured priority will act as a virtual router with a pre-defined gateway IP address and will respond to the ARP or ND request from machines connected to the LAN with a virtual MAC address. Virtual MAC address format: manufacturer code (0000.0c), virtual MAC address (07.ac), HSRP group number (2f) HSRP message: All routers in HSRP send or.
