greetings
i would like to get more details on GRE in my scenario
as i mentioned above, i have two main controllers in L3 mode and two anchor in HA
how many tunnels are needed from-to each controller?
how tunnels should be configured to have proper path/flow?
lets put some IPs and get scenarios
WLC1 - 10.0.1.1
WLC2 - 10.0.2.0
anchor1 - 192.168.1.2
anchor2 - 192.168.1.3
VRRP for anchor 192.168.1.1 (priority 200 for anchor1)
flow - may come from each of the WLC independently (AP groups)
q1) how many tunnels are needed PER each WLC?
- ONE towards VRRP IP? two to each anchor? how system will know which path is correct?
q2) how many tunnels are needed on anchor devices? what should be source IP of that tunnel? VRRP?
Or possibly tunnel groups are required? Is there a mechanism to have priority on specific tunnel?
