[vpn] Transparent bridging over Cisco VPN?

[Jim Terry]

hi all,

I have never used an 800 Cisco router but the books have always said it is
the first router to use Cisco IOS.  I do not see any documentation that
shows it has less commands than any other. My guess is the 800 can do any
command the others can do.
