D. designated router








 

Suggested Answer: C

GLBP Active Virtual Gateway -
Members of a GLBP group elect one gateway to be the active virtual gateway (AVG) for that group. Other group members provide backup for the AVG in the event that the AVG becomes unavailable. The AVG assigns a virtual MAC address to each member of the GLBP group. Each gateway assumes responsibility for forwarding packets sent to the virtual MAC address assigned to it by the AVG. These gateways are known as active virtual forwarders (AVFs) for their virtual MAC address.
. Load sharing is achieved by the AVG
The AVG is responsible for answering Address Resolution Protocol (ARP) requests for the virtual IP address replying to the ARP requests with different virtual MAC addresses.
