GLBP Benefits

BDE

GLBP stands for Gateway Load Balancing Protocol, a Cisco proprietary protocol that provides redundancy and load balancing for IP traffic across multiple routers. The benefits of GLBP include:

A. GLBP supports up to eight virtual forwarders per GLBP group.

GLBP allows multiple routers to share the same virtual IP address as the default gateway for a subnet. Each router participating in GLBP can be assigned a different virtual forwarder (i.e., MAC address) for that virtual IP address, allowing for redundancy and load balancing.

B. GLBP supports clear text and MD5 password authentication between GLBP group members.

GLBP uses authentication to ensure that only authorized routers participate in a GLBP group. Authentication can be configured using clear text or MD5 password authentication.

D. GLBP supports up to 1024 virtual routers.

GLBP allows for the creation of multiple GLBP groups, each with its own virtual IP address and virtual forwarders. GLBP supports up to 1024 virtual routers.

E. GLBP can load share traffic across a maximum of four routers.

GLBP can load balance traffic across up to four active virtual forwarders. This allows for more efficient use of available network resources and improved network performance.

F. GLBP elects two AVGs and two standby AVGs for redundancy.

GLBP uses an Active Virtual Gateway (AVG) to manage virtual forwarder assignments and load balancing. To provide redundancy, GLBP elects two AVGs and two standby AVGs per GLBP group. If the primary AVG fails, one of the standby AVGs will take over.

C. GLBP is an open source standardized protocol that can be used with multiple vendors.

This statement is incorrect. GLBP is a Cisco proprietary protocol and is not an open source standardized protocol that can be used with multiple vendors. It is only available on Cisco devices.
