GLBP is a Cisco proprietary protocol that attempts to overcome the limitations of existing This section will first go over the configuration process steps and commands that are used to perform a basic GLBP configuration. An example. In the previous lesson we showed you a load balancing mechanism and I’ll still argue that that’s the best way to go. Gateway Load Balancing Protocol – GLBP is .
I have years of experience in design, analysis, operation, and optimization of infrastructure solutions for enterprise-scaled network. See All Related Articles.
R1 config-if glbp 10 preempt. R1 config-if glbp 1 load-balancing weighted. The object-number can be any number between 1 and Specifies a load balancing method where each virtual forwarder in turn is included in address resolution replies for the virtual IP address. For a virtual forwarder the state can be configurationn of the following: The difference here is that there will be load balancing occurring between the two routers. Configure the GLBP redirect timers.
Configure GLBP in Cisco IOS Router
So we can see we’re active, virtual IP address but the reality is there is far more to it than what we can even get into in this discussion.
Specifies a load balancing method that is dependent. An AVF with bigger weight value will get more traffic redirected to it. Figure shows the network topology for the configuration that follows, which shows how to configure GLBP using commands covered in this chapter.
R2 config-if glbp 10 priority Figure 1 GLBP example topology. Here is a sample output, similar to what we saw for HSRP. Virtual gateway is attempting to become the active or standby virtual gateway.
If a key-chain is configured with the command above, follow these next few steps to create the key-chain.
The main difference is that GLBP allows for load balancing between the two routers rather than using just one and leaving the other unused until needed. R2 copy running-config startup-config. Which MAC address it returns depends on which load-balancing algorithm it is configured to use. See All Related Store Items. Return to Beginning Previous Section. Change the default GLBP load balancing behavior to using weighting. Table 4 covers all the commands that are required to perform these steps.
Router config hostname R1.
GLBP Configuration on Cisco
It’s the most advanced, but it can generate some traffic flow that is downright undesirable. If failure happens on the AVG, the role will be granted glnp another router with next highest priority. Create and enter into key chain — key configuration mode. About Affiliates Cisco Systems, Inc. Specifies cpnfiguration load balancing method based on the MAC address of a host where the same forwarder is always used for a particular host while the number of GLBP group members remains unchanged.
Cisco Gateway Load Balance Protocol (GLBP) Configuration Process and Commands
Different interfaces can be tracked to decrement the GLBP weighting by varying amounts. R1 config-if glbp 10 timers 5 R1 copy running-config startup-config. Subscribe to newsletter To be informed of the latest articles, subscribe:. Router-A show glbp brief. In this section, the commands that are covered will extend to those that modify the default behavior of the GLBP process. Forwarder preemption works in a similar way, except that forwarder preemption uses weighting instead of priority and is enabled by default.
GLBP preemption is disabled by default. First Hop Redundancy Protocol, that’s a gateway protocol. GLBP is a workable technology. Create and enter into key chain — key configuration mode using a key number of 1.
Weighted algorithm distribute traffic to each AVF based on the weight value assigned to them. I hope that this article provided some insight into the configuration steps that are required to configure GLBP and get it up and running. Feel free to contact us if you have any further questions or concerns.
You could only get any kind of load balancing if you add multiple groups. Specifies that GLBP will load balance using the host-dependent method.
