Difficulty: EasyFirst Hop Redundancy Protocols (HSRP and VRRP)

Which of the following statements correctly compare the default operational characteristics and parameters of HSRP (v1) and VRRP (v2)? (Select two.)

  1. HSRPv1 uses virtual MAC addresses in the format 0000.0c07.acXX, whereas VRRPv2 uses the format 0000.5e00.01XX.Answer
  2. HSRP names the primary forwarding gateway the Active router, whereas VRRP names it the Master router.Answer
  3. C
    HSRP permits assigning an interface's physical IP address as the virtual IP address, whereas VRRP strictly forbids sharing an interface IP address.
  4. D
    HSRP enables interface preemption by default, whereas VRRP requires preemption to be explicitly configured.

Answer

The correct statements are that HSRPv1 uses virtual MAC addresses formatted as 0000.0c07.acXX while VRRPv2 uses 0000.5e00.01XX, and HSRP designates the forwarding router as Active while VRRP designates it as Master.
HSRPv1 and VRRPv2 differ in virtual MAC schemes (0000.0c07.acXX vs 0000.5e00.01XX) and role naming conventions (Active/Standby in HSRP vs Master/Backup in VRRP).

Step-by-Step Solution

1
Analyze virtual MAC address structure for both protocols
HSRPv1 uses standard MAC prefix 0000.0c07.ac followed by the group ID. VRRPv2 uses 0000.5e00.01 followed by the group ID.
Each protocol reserves a specific IEEE OID/MAC range for virtual gateway identification.
2
Compare role terminology between Cisco proprietary HSRP and open standard VRRP
HSRP uses Active/Standby roles, whereas VRRP uses Master/Backup roles.
Standardization differences lead to distinct terminology for equivalent primary/secondary forwarding roles.
3
Evaluate IP address assignment and preemption rules
VRRP supports using an interface's physical IP as the virtual IP address and enables preemption by default. HSRP requires a separate virtual IP address and disables preemption by default.
Differentiates implementation behavior between the two First Hop Redundancy Protocols.
