GLBP (Gateway Load Balancing Protocol)

Configure GLBP to use the tracked object to influence its weighting. As a matter of fact, we never explicitly changed the priority on R1 from the default of R1 config-if glbp 1 authentication key-chain testchain. Hi guys, can someone send the latest dumps my way plz?? Although it is possible to configure multiple virtual router groups to achieve load balancing in case of HSRP and VRRP, but it requires configuring different default gateways on different hosts, which is an extra administrative burden.

GLBP has three authentication types: In this article, networking consultant Sean Wilkins takes the concepts covered in his earlier ” Introduction to GLBP ” article and discusses how those concepts can be applied to real devices. But the trick here is it does not always give the same answer to that question: If there are multiple routers acting as virtual router backup, the one with the highest priority becomes the virtual router master if the original virtual router master fails.


These include GLBP timers helloholdredirect and timeoutaltering the default load balancing behavior the default is round robinconfiguring GLBP authentication, and basic interface tuyorial.

The router R2 is configured with the default priority As a result, client hosts on the LAN receive uninterrupted connectivity through their default gateway Premium Membership Become a member to interact with all questions and practice labs!

It is time for verification using the show standby command. Tables 2 and 3 show the basic commands that are required to configure GLBP between the two devices shown in Figure 1.

In this case we only have four gateways so surely they are all elected AVFs. R2 config-if ip address Because of this, a number of different technologies have been developed to provide redundancy at every point within the network. There can be multiple virtual router backups, though in the figure above routers R2 and R3 are virtual router backups. You may verify GLBP configuration and find out which role each router is playing using the show glbp command.
