Which statement best describes the function of Hot Standby Router Protocol (HSRP)?

  • HSRP specifies a single IP address that all routers in the group must use.
  • HSRP defines a set of routers that represent one virtual, fault-tolerant router.
  • HSRP provides a round-robin gateway selection process to increase fault tolerance.
  • HSRP defines a frame-tagging scheme that allows end stations to use any router as a gateway.
Explanation:

Hot Standby Router Protocol (HSRP) is specified by RFC 2281. The primary function of HSRP is to define a set of routers that work together to represent one virtual, fault-tolerant router. Thus, redundancy is provided in the event that any one of the routers fails. HSRP can be configured on the following interface types:

  • Routed ports
  • Switched virtual interfaces (SVI)
  • Etherchannel port channels

HSRP does use a single IP address to represent a group of routers, but this does not fully describe the function of HSRP.

HSRP does not provide round-robin gateway selection. HSRP uses router priority to select a primary and standby router.

HSRP does not define a frame-tagging scheme that allows end stations to use any router as a gateway. End stations use the virtual IP address of a group of HSRP routers as the default gateway.
