What is 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. e.g- if the group number is 10 then the last 8 bits will be 0a.
Which MAC address is an HSRP version 2?
0000.0C9F
HSRP version 2 permits an expanded group number range, 0 to 4095, and consequently uses a new MAC address range 0000.0C9F.
Which one is given the right virtual MAC address for HSRP?
0000.0c9f
The virtual MAC address of an HSRP router is 0000.0c9f.
What does HSRP stand for?
Hot Standby Router Protocol
In computer networking, the Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway.
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.
What is the difference between HSRP version 1 and 2?
Version 1 is the default version of HSRP. HSRP version 2 uses the new IP multicast address 224.0. This new multicast address allows CGMP leave processing to be enabled at the same time as HSRP. HSRP version 2 permits an expanded group number range, 0 to 4095, and consequently uses a new MAC address range 0000.0C9F.
What is VRRP MAC address?
5.1 VRRP over Ethernet. 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.
How do I know if my router is HSRP active?
Showing HSRP State Information
- Problem. You want to see current HSRP information, such as which router is primary.
- Solution. To view the HSRP information, use the following EXEC command: Router2# show standby.
- Discussion.
What are two requirements for an HSRP group?
What are two requirements for an HSRP group? (Choose two.) Exactly one active router: Only one Active Router per HSRP group will be elected based on highest priority. In case of equal priority, Highest IP address will be elected as Active Router. One or more standby routers: There can be one or more Standby Routers.
Is HSRP a Layer 2 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.
Can 2 HSRP routers become active active?
In HSRP, two or more routers give an illusion of a single virtual router. This allows you to configure two or more routers as standby routers and only a single router as the active router.
