[nsp] What version of IOS should I be using...?

[Ryan Spott]

I have a 7206vxr with a pa-t3 card in it.

I would like to do the following with it:

BGP
Vlan Switching dot1q
support more than one fast ethernet interface.

My current IOS: Version 12.1(2) does not allow for me to make dot1q 
sub interfaces on the existing ethernet card.

Could anyone here make any recommendations or point me at a Cisco web 
page that would guide me through this?


Thanks in advance (and thanks for letting me lurk :)
