Hello,
we have multiple L2 VLANs configured [mobility is disabled], which are connected via a trunk to a router that relays to an external DHCP server.
I am trying to figure some details on the DHCP process while the client is roaming.
At moment of the roaming, a user has an IP on VLAN 1 and he associates to another AP which is offered to use VLAN2.
Just after the association:
Will the client reset his IP and start the DHCP process with DHCPDISCOVER?
or
Will get connected to VLAN 2 and while still having his VLAN1 IP send a DHCP REQUEST?
Then get NO from DHCP server and re-initialise DHCP lease process?
