What does GLBP stand for?
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 supports clear text and MD5 password authentication between GLBP group members. GLBP is an open source standardized protocol that can be used with multiple vendors. GLBP supports up to 1024 virtual routers. GLBP can load share traffic across a maximum of four routers.
What is the purpose of HSRP?
It provides a continuous network connection when a router fails. It prevents a rogue switch from becoming the STP root. It enables an access port to immediately transition to the forwarding state.
Is GLBP better than HSRP?
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 protocol does HSRP work on?
HSRP, or Hot Standby Router Protocol, is one of the commonly used First Hop Redundancy Protocols (FHRP). We also have Virtual Router Redundancy Protocol (VRRP) and Gateway Load Balancing Protocol (GLBP)….HSRP States.
| Version 1 | Version 2 | |
|---|---|---|
| Multicast Address | 224.0.0.2 | 224.0.0.102 |
What is GLBP and how does it work?
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 GLBP (gateway load balancing protocol)?
GLBP (Gateway Load Balancing Protocol) GLBP stands for Gateway Load Balancing Protocol and just like HSRP / VRRP it is used to create a virtual gateway that you can use for hosts. If you have no idea what a virtual gateway is then read my Introduction to Gateway Redundancy first.
How many routers are in a GLBP group?
There are two types of routers in a GLBP group use in redundancy and load balancing: Within a GLBP group, one virtual router (gateway) is elected as the Active Virtual Gateway (AVG), and its responsibility for the operation of the protocol.
What is GLBP priority and how to configure it?
Priority also determines if a GLBP router functions as a backup virtual gateway and the order of ascendancy to becoming an AVG if the current AVG fails. You can configure the priority of each backup virtual gateway with a value of 1 through 255 using the glbp priority command.
