WebHSRP (Hot Standby Router Protocol) is a Cisco proprietary First Hop Redundancy Protocol (FHRP). HSRP first hop redundancy mechanism provides alternative path as a proactive action for any failure on a device.

WebApr 10, 2024 · The NHRP network ID is used to define the NHRP domain for an NHRP interface and differentiate between multiple NHRP domains or networks, when two or more NHRP domains (GRE tunnel interfaces) are available on the same NHRP node (switch). The NHRP network ID helps keep two NHRP networks (clouds) separate when both are … WebWith this option, GRE tunnels will mimic the behavior of physical interfaces, going into a down state if the far end of the tunnel becomes unavailable. This means that you can use standby track on a tunnel interface, which in turn means that you can now make your HSRP priority change in response to problems elsewhere in the network.
