Re: Way OT: Aironet AP's -- Functionally more repeater or more bridge? posted 12/22/2005

Hi Tim,

The BVI interface gets the IP address and the Radio interface and ethernet
interface are just placed in the bridge group of the BVI (group 1 by
default).

It just behaves like a bridge.

If vlans are required you need to enable 802.1q subinterfaces on both the
radio and ethernet interface(int dot11radio 0.6 & int fastethernet0.6. these
will be assigned to a different bridge group than the main interface (eg
vlan 6 subifs are both in vlan 6) but you will still only need BVI1 to
communicate with the AP (just like the management IP on a switch)

Hope this helps,

Pete
