I have two Cisco 3750 switch which configured HSRP.

CISCO MAC ADDRESS 0000.0C9F. MAC

HSRP Version 1 and 2 HSRPv1 HSRPv2 Group Numbers 0 – 255 0 – 4095 Virtual MAC address (XX = group number) (XXX = group number) Multicast Address 224.0.0.2 224.0.0.I have some question about HSRP in 3750 switch. What are HSRP version 1 and 2 group numbers? 192.168.1.254 will be the virtual gateway IP address. We will do this on the VLAN 1 interfaces of SW1 and SW2: SW1 & SW2 (config)#interface Vlan 1 (config-if)#standby 1 ip 192.168.1.254 Use the standby command to configure HSRP.

We will do this on the VLAN 1 interfaces of SW1 and SW2: Use the standby command to configure HSRP. Which is the virtual gateway IP address for HSRP? Each standby group emulates a single virtual router (default gateway).

If the standby router fails or becomes the active router, another router is elected as the standby router. If the active router fails, the standby router takes over as the active router. What happens to the HSRP group if a router fails?Īdditional routers in the HSRP group remain in the Listen state. To configure an authentication string for the Hot Standby Router Protocol (HSRP), use the hsrp authentication command in HSRP interface configuration mode.

Which command permits the verification of your HSRP configuration? All HSRP member nodes will go through an election process and the router with either the highest configured priority or IP (optional preempt) and is elected as the active device. The only way 2 routers would be active/active, is for some misconfiguration so that the two cannot communicate with each other.

All the routers in a single HSRP group shares a single MAC address and IP address, which acts a default gateway to the local network. In HSRP, two or more routers gives an illusion of a virtual router. Hot Standby Router Protocol (HSRP) is a CISCO proprietary protocol, which provides redundancy for a local subnet. To restore the default values, use the no form of this command. To configure Hot Standby Router Protocol (HSRP) preemption and preemption delay, use the hsrp preempt command in HSRP interface configuration mode. To configure Hot Standby Router Protocol (HSRP) priority, use the hsrp priority command in HSRP interface configuration mode. HSRP 2 uses the virtual MAC address of 0000.0c9f. HSRP v1 uses the virtual MAC address of 0000.0c07. HSRP (Hot Standby Router Protocol) has two versions: v1 and v2. What command will display the information held on the configuration of HSRP? Additional HSRP member routers transition from the listen state after the holdtime expires on the hello message. What happens when an HSRP active router fails? (Select two.) The HSRP standby router becomes the active router after the holdtime expires on the hello message. What happens when an HSRP active router fails? Where this doesn’t directly relate to an HSRP error, this message shows the triggering of another problem. HSRP Error 1: Standby SUPADDR Error The Standby SUPADDR error message indicates a Spanning Tree Protocol loop or possibly a router and switch configuration issue.

Configure HSRP group and virtual IP address using the standby command.

Configure normal IP address on interface (cannot be the same as HSRP virtual IP).

To achieve basic HSRP configuration, you need to do the following:
