What is a potential disadvantage when implementing HSRP as compared to GLBP?

  • HSRP does not provide load balancing with multiple active routers.
  • HSRP does not function in a multivendor environment.
  • HSRP does not have the capability to support IPv6 addresses.
  • HSRP provides default gateway failover only when the active router fails.

Explanation: HSRP is a first-hop redundancy protocol that can utilize a group of routers, where a single router is acting as the default gateway and all other HSRP routers will maintain a backup status. GLBP supports load balancing, where multiple active routers can share the traffic load at a single time. Both HSRP and GLBP are Cisco proprietary. HSRP provides default gateway failover when pre-set conditions are met or when the active router fails, and HSRP can support IPv6 addressing.
