How many routers can participate in GLBP?

GLBP supports up to 1024 virtual routers (GLBP groups) on each physical interface of a router, and up to 4 virtual forwarders per group.

When using GLBP if the AVG router fails what router becomes the next AVG?

Since there is just one AVG per a GLBP group, the procedure is pretty simple: each candidate AVG has a priority value assigned; the highest priority router becomes an active AVG, the next by priority becomes a standby AVG.

Which of the following Glbp load balancing options is configured if the host is guaranteed the use of the same virtual MAC address?

Which of the following GLBP load-balancing options is configured if the host is guaranteed the use of the same virtual MAC address? The Layer 2 VLAN number should be mapped to the Layer 3 subnet for ease of use and management.

What is gateway Load Balancing?

Gateway Load Balancer makes it easy to deploy, scale, and manage your third-party virtual appliances. It gives you one gateway for distributing traffic across multiple virtual appliances, while scaling them up, or down, based on demand.

Why would you use GLBP over HSRP and VRRP?

Why would you prefer GLBP over HSRP and VRRP? GLBP provides load-balancing within a single subnet. GLBP uses a virtual IP address while HSRP and VRRP use physical IP addresses. GLBP is easy to configure as GLBP configuration is provided to hosts through DHCP.

How Does Load Balancing Work?

Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.

What happens if no load-balance algorithm is specified for GLBP?

If no load-balance algorithm is specified then GLBP will operate in an identical fashion to HSRP, the AVG will only respond to Address Resolution Protocol (ARP) requests with its own Virtual Forwarder (VF) MAC address, and all traffic will be directed to the AVG with no occurrence of load balancing.

What is Cisco gateway load balancing protocol (GLBP)?

The purpose of this document is to discuss the options that Cisco Gateway Load Balancing Protocol (GLBP)-one of Cisco First Hop routing Protocols family-offers in regard to load balancing across multiple gateways. For those unfamiliar with GLBP an introductory paper can be found in the reference section of this document.

When is host dependent load balancing not recommended?

Host dependent load balancing is not recommended for situations where there are a small number of end hosts, for example less than 20, unless there is also a requirement that individual hosts must always use the same forwarder. The larger the number of host, the less likely it is to have an imbalance in…

What is round robin load balancing in GLBP?

With Round Robin each VF MAC address is used sequentially in ARP replies for the virtual IP address. Round Robin load balancing is suitable for any number of end hosts. The GLBP load balancing discussed in this document has been available since the first release of GLBP, supported in the following versions:
