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. This feature was introduced.

2005年12月12日 · GLBP differs from Cisco Hot Standby Redundancy Protocol (HSRP) and IETF RFC 3768 Virtual Router Redundancy Protocol (VRRP) in that it has the ability to load balance over multiple gateways. Like HSRP and VRRP an election occurs, but rather than a single active router winning the election GLBP elects an Active Virtual Gateway (AVG).

2022年3月11日 · 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.

Gateway Load Balancing Protocol (GLBP) is a Cisco proprietary protocol that attempts to overcome the limitations of existing redundant router protocols by adding basic load balancing functionality. In addition to being able to set priorities on different gateway routers, GLBP allows a weighting parameter to be set.

2019年8月9日 · Gateway Load Balancing Protocol (GLBP) is one of First Hop Redundancy Protocol (FHRP) which provides redundancy like other First Hop Redundancy Protocol, also provides load Balancing. It is a Cisco proprietary protocol which can perform both functions.

2018年12月27日 · 1. GLBP-AVG：活动的虚拟网关，每个glbp组中选举一台当作AVG用来给GLBP组成员分配虚拟mac， 2. GLBP-AVF： AVG分配完MAC后，每台分配到虚拟mac的成员转发数据包，叫做AVF,一个组最多4个活动AVF，其余listen 参数： 1. hello包3s一次发送， holdtime时 …

2018年8月21日 · GLBP全称Gateway Load Balancing Protocol(网关负载均衡协议)，是思科的专有协议。GLBP不仅提供冗余网关，还在各网关之间提供负载均衡。他弥补了现有的冗余路由器协议的局限性， 设计GLBP的目的是自动选择和同时使用多个可用的网关。

2013年4月15日 · Gateway Load Balancing Protocol or GLBP differs from Cisco Hot Standby Redundancy Protocol or HSRP and IETF RFC 3768 Virtual Router Redundancy Protocol or VRRP in that it has the ability to load balance over multiple gateways.

In this article we will discuss the similarities and differences between the 3 “First Hop Redundancy” protocols supported by Cisco devices. These are Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP) and Gateway Load Balancing Protocol (GLBP). The main purpose of the above protocols is to provide redundancy…
