I am getting conflicting info as to whether GLBP (using a pair of 6509 sup 720's load balances its traffic by default). Anybody know for sure?
Output of show glbp...you can see at the end it indicates round-robin load balancing...
GigabitEthernet1/2.99 - Group 3
State is Standby
199 state changes, last state change 9w0d
Virtual IP address is 10.66.33.1
Hello time 250 msec, hold time 750 msec Next hello sent in 0.032 secs
Redirect time 600 sec, forwarder time-out 14400 sec
Authentication MD5, key-string "sssss"
Preemption enabled, min delay 180 sec
Active is x.x.x.3, priority 15 (expires in 0.832 sec)
Standby is local
Priority 10 (configured)
Weighting 100 (default 100), thresholds: lower 1, upper 100
Load balancing: round-robin
From a Cisco GLBP doc that indicates that if no load balancing is specified, "all traffic will be directed to the AVG with no occurrence of load balancing."
