What is the MAC address of HSRP?

What is the MAC address of HSRP?

HSRP version 1 utilizes the MAC address range from 0000.0C07. AC00 through 0000.0C07. ACFF (00 = Group 0, FF = Group 255), while HSRP version 2 utilizes the MAC address range from 0000.0C9F.

What is HSRP default priority?

By default, the priority is 100 but the highest priority value becomes the active router for the HSRP group.

What are the default timers for HSRP?

The default hold time is 10 seconds for both versions of HSRP (v1 and v2), which is roughly three times the default hello time. The hold time has to be sufficiently larger than the hello time to ensure that the standby router does not take over the active role every time there’s a short communication break.

What is the default priority value on HSRP configured router?

100
The default HSRP priority is 100. If you want an HSRP router to be elected as the active router, you should set the priority to a value higher than the default of 100.

What is VRRP MAC address?

Over Ethernet, VRRP routers use a common MAC address of the format 00:00:5E: 00:01:XX. The first three octets are derived from the IANA’s OUI. The next two octets (00:01) indicate the address block assigned to the VRRP protocol by IANA.

What protocol does HSRP use?

HSRP is an application layer protocol. HSRP version 1 uses UDP port number 1985 and multicast address 224.0. 0.2 and version 2 uses UDP port 1985 and 224.0. 0.102 as multicast address.

How do I set HSRP priority?

To configure Hot Standby Router Protocol (HSRP) priority, use the hsrp priority command in HSRP interface configuration mode. To restore the default values, use the no form of this command.

How do I configure HSRP protocol?

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

1. Configure normal IP address on interface (cannot be the same as HSRP virtual IP)
2. Bring interface up (no shutdown)
3. Configure HSRP group and virtual IP address using the standby command.

What is virtual MAC address?

A virtual MAC address is a floating entity shared by the primary and the secondary nodes in an HA setup. In an HA setup, the primary node owns all of the floating IP addresses, such as the MIPs, SNIPs, and VIPs.

Which is a multicast MAC address?

The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. The remaining portion of the multicast MAC address is created by converting the lower 23 bits of the IP multicast group address into 6 hexadecimal characters.
