redundancy protocols GLBP (Gateway Load Balancing Protocol)

GLBP (Gateway Load Balancing Protocol) GLBP (Gateway Load Balancing Protocol) is an another redundancy protocol. It is a Cisco proprietary redundancy protocol like HSRP. So ,you can only use this protocol on Cisco devices. GLBP has a key benefit that HSRP and VRRP do not have. This is load-balancing. GLBP provides load balancing over multiple […]

redundancy protocols VRRP (Virtual Router Redundancy Protocol), protocols for redundancy

VRRP(Virtual Router Redundancy Protocol) VRRP(Virtual Router Redundancy Protocol) is a standard based redundancy protocol. The configuration of this protocol is like HSRP with only small differences. In VRRP the active router is called Master, and the remainning ones are all Backup routers. So there can be multiple backup routers. VRRP (Virtual Router Redundancy Protocol) By […]

redundancy protocols HSRP example (Hot Standby Router Protocol) topology, protocols for redundancy

HSRP Configuration on Cisco IOS In this section we will do an HSRP configuration to understand the issue better. To do this wewill use the below topology. At the end of this article, you will find the GNS3 configuration lab of this lesson. HSRP Example Topology Before the HSRP configuration, we must prepare our topology. […]

redundancy protocols hsrp (Hot Standby Router Protocol), protocols for redundancy

HSRP(Hot Standby Router Protocol) HSRP(Hot Standby Router Protocol) is a Cisco proprietary redundancy protocol. With this protocol one “virtual ip address” is assigned and always this address is used to go through the routers. At the backplane, the gateway interfaces’s ip address still exist. But it seems that only one interface exist and the ip […]

network redundancy, protocols for redundancy

Network Redundancy Protocols Redundancy is a common point for today’s topologies. Especially in mission-critical networks it is not acceptible that using only one gateway to reach a point. Because one gateway means single point of failure. With multiple gateways, you can still reach the remote node even if the gateway that you connect fails. As […]
