What is AVG and AVF in GLBP?
AVG role is used to load-balance and respond to ARP requests. AVF role manages one or more virtual MACs and is responsible for packet forwarding. AVG redundancy is controlled by GLBP priority and AVF redundancy is implemented using AVF weight value and two additional timers.
What is the difference between HSRP and GLBP?
The main difference is that GLBP allows the load balancing of traffic among the master and standby routers while in HSRP (and VRRP) the standby routers do not help handle traffic. With GLBP, the single virtual IP address is associated with one virtual MAC address per GLBP member.
What is Cisco GLBP?
Gateway Load Balancing Protocol (GLBP) protects data traffic from a failed router or circuit, like Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP), while allowing packet load sharing between a group of redundant routers.
What is the benefit of GLBP?
GLBP Benefits GLBP supports up to 1024 virtual routers (GLBP groups) on each physical interface of a router, and up to 4 virtual forwarders per group. The redundancy scheme of GLBP enables you to preempt an active virtual gateway with a higher priority backup virtual gateway that has become available.

What is difference between VRRP and GLBP?
One of the main differences is that VRRP is industry-standard while HSRP and GLBP are Cisco-proprietary protocols. VRRP and HSRP distribute themselves over a single layer 3 ethernet switch or a router to be the active one in a group, whereas GLBP can target up to four routers by configuring load balancing schemes.
Which of the following is the default load balance method of GLBP?
By default, the load balancing behavior of GLBP is to use round robin, which will always result in a distribution of hosts to AVFs.
What is difference between HSRP VRRP and GLBP?
What is the default weight value of GLBP group configuration?
Table 4 – GLBP Complex Configuration Commands
| 1 | Configure the GLBP hello and hold timers. |
|---|---|
| 2 | (Optional) Configure the GLBP weighting values. Note: With GLBP, each of the Active Virtual Forwarders (AVF) is assigned a weight (default is 100); if the defaults are not altered, then each of the AVFs will be equally loaded. |
