If we are using a router why do we need to create bvi?

Can't the router route the packets to wired as well as wireless clients? Why create bvi?

Are the wired and wireless clients connected to different interfaces on the router? If not, then the router shouldn't have to route anything, assuming the wired and wireless clients are on the same subnet (layer 3 network). –  joeqwerty Feb 3 '12 at 11:39
actually i have used switch ports for wired and dot11radio interface of cisco 1800 router for wireless. So, are we not using a router here? –  prats Feb 3 '12 at 18:12
prats: That looks like two different interfaces and if you want them routed as a unit, you need to bridge between them, so a BVI. –  Vatine Feb 6 '12 at 13:42
vatine: But a router can route between different interfaces then why do we need a BVI –  prats Feb 6 '12 at 18:25
