Zorluk: KolayFirst Hop Redundancy Protocols (HSRP and VRRP)

A network administrator is evaluating First Hop Redundancy Protocols (FHRP) for deployment across campus gateways. Which two statements correctly describe default operational characteristics of HSRPv1 compared to VRRPv2?

  1. VRRP enables router preemption by default, whereas HSRP requires preemption to be explicitly configured under interface settings.Cevap
  2. B
    HSRP permits configuring an active router's physical IP address as the group virtual IP address, whereas VRRP strictly forbids matching the virtual IP with an interface IP.
  3. HSRP designates redundancy roles as Active and Standby, whereas VRRP uses Master and Backup to define router states.Cevap
  4. D
    VRRP sends periodic master advertisement messages to IPv4 multicast address 224.0.0.2, whereas HSRPv1 sends hello messages to 224.0.0.18.

Cevap

VRRP enables preemption by default while HSRP requires explicit preemption configuration, and HSRP uses Active/Standby role terminology while VRRP uses Master/Backup.
VRRP has preemption enabled by default and uses Master/Backup role terminology, whereas HSRP has preemption disabled by default and uses Active/Standby role terminology.

Adım Adım Çözüm

1
Evaluate preemption default settings for HSRP and VRRP
VRRP preemption is enabled by default; HSRP preemption is disabled by default.
By protocol specification, VRRP automatically preempts lower-priority master routers unless preemption is manually disabled, whereas HSRP requires interface preemption syntax.
2
Examine operational role terminology across both protocols
HSRP uses Active and Standby; VRRP uses Master and Backup.
This aligns with RFC standards for VRRP compared to Cisco proprietary HSRP conventions.
