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.
