What is valid HSRP virtual MAC address? Virtual MAC address : MAC address is generated automatically by HSRP. The first 24 bits will be default CISCO address (i.e. 0000.0c). The next 16 bits are HSRP
What is valid HSRP virtual MAC address?
Virtual MAC address : MAC address is generated automatically by HSRP. The first 24 bits will be default CISCO address (i.e. 0000.0c). The next 16 bits are HSRP ID (i.e. 07.ac). The next 8 bits will be the group number in hexadecimal.
Can HSRP be active active?
Traditional HSRP operates in an active/passive fashion. One router will pass traffic, and the other will not. The standby router will take over the active role during a failure. HSRP with vPC operates in both active/active and active/passive at the same time.
Why is HSRP not working?
If the switch is configured for HSRP but does not recognize its HSRP peers, the switch fails to receive HSRP hellos from the neighbor switch. When you troubleshoot this issue, perform the following steps: Check HSRP Verify Physical Layer Connectivity. Check HSRP configurations.
How do I verify HSRP configuration?
To activate the Hot Standby Router Protocol (HSRP), use the hsrp ipv4 command in HSRP interface configuration mode. To disable HSRP, use the no form of this command.
What layer is HSRP?
application layer protocol
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.
Why would you use GLBP instead of HSRP?
Why would you prefer GLBP over HSRP and VRRP? GLBP provides load-balancing within a single subnet. GLBP uses a virtual IP address while HSRP and VRRP use physical IP addresses. GLBP is easy to configure as GLBP configuration is provided to hosts through DHCP.
What happens when an HSRP active router fails?
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. Additional HSRP member routers transition from the listen state after the holdtime expires on the hello message.
How do I configure HSRP?
To achieve basic HSRP configuration, you need to do the following:
- Configure normal IP address on interface (cannot be the same as HSRP virtual IP)
- Bring interface up (no shutdown)
- Configure HSRP group and virtual IP address using the standby command.

Which is better HSRP or VRRP?
As you can see there sin’t a big difference between the two protocols. The primary difference between HSRP versus VRRP would be that HSRP is proprietary to Cisco and can only be used on Cisco devices. VRRP is a standards based protocol and is vendor independent allow some flexibility when choosing network devices.
What is the MAC address associated with HSRP?
Because host workstations are configured with their default gateway as the HSRP standby IP address, hosts must communicate with the MAC address that is associated with the HSRP standby IP address. This MAC address is a virtual MAC address that is composed of 0000.0c07.ac**.
What happens if an active router fails to run HSRP?
If the active router fails, the standby assumes the packet forwarding duties. Although an arbitrary number of routers may run HSRP, only the active router forwards the packets that are sent to the virtual router IP address.
Where does the hello packet come from in HSRP?
The active router sources hello packets from its configured IP address and the HSRP virtual MAC address. The standby router sources hellos from its configured IP address and the burned-in MAC address (BIA). This use of source addressing is necessary so that HSRP routers can correctly identify each other.
Is the HSRP virtual IP address the default gateway?
HSRP is not intended as a replacement for existing dynamic protocols. Most IP hosts have an IP address of a single device configured as the default gateway. When HSRP is used, the HSRP virtual IP address is configured as the host’s default gateway instead of the IP address of the device.
