Dear team,
I am working with an implementation with 30 Instant APs 305 Aruba and need to implement Roaming between Virtual controllers.
There are 2 buildings with different subnets and VLANS, and I was not able to find a clear documentation to configure L3 roaming between clusters.
I have seen some forums mentioning that VLANs shouldnt match at both VC, and another that VLANS should match .
I have attached both VC controllers, and "L3roaming events" for you to check.
L3 tunnel are being established properlly, and IP is mantained for a while when one user from VC 650 moves to VC638, but for some reason the session is being disconnected.
I have upgraded all VC and APs to 8.3 latest available version.
This is Controller VC650: L3 configuration:
l3-mobility
home-agent-load-balancing
virtual-controller 192.168.7.196
virtual-controller 192.168.7.78
subnet 192.168.192.64 255.255.255.192 505 192.168.7.78
subnet 192.168.191.0 255.255.255.0 501 192.168.7.196
This is controller VC538: L3 Configuration:
l3-mobility
home-agent-load-balancing
virtual-controller 192.168.7.78
virtual-controller 192.168.7.196
subnet 172.18.0.0 255.255.255.240 192 192.168.7.78
subnet 192.168.189.0 255.255.255.0 190 192.168.7.78
subnet 192.168.160.0 255.255.255.128 160 192.168.7.78
subnet 192.168.191.0 255.255.255.0 501 192.168.7.196
subnet 192.168.192.64 255.255.255.192 505 192.168.7.78
Thank you !!
