Given the fact that the AVG (in GLBP) responds to all ARP requests for the GLBP virtual IP address, how do the switches update their CAM tables quickly enough to ensure that the packet goes to the correct AVF?
GLBP IP address = 22.214.171.124
2 GLBP members #1 & #2.
#1 is the GLBP AVG
#1 MAC = 0000.0000.aaaa
#2 MAC = 0000.0000.bbbb
When a PC ARPs and #1 decides that the AVF #2 will forward the data for that PC it will source its ARP request with the MAC address 0000.0000.bbbb (#2).
The attached switch will update its CAM thinking that the MAC 0000.0000.bbbb is connected to #1.
Does #2 continually send out Gratuitous ARPs?
