I don't understand why this doesn't work. I have a 2912 switch and a 2621 Router. I'm just trying to setup basic vlan routing but I can't get the encapsulation working on the router, rather I can't even find the command.
I setup a dot1q trunk port on the switch and connected fa 0/0 of the router to it.
So now I'm trying to setup dot1q encap on the 2621 router but I can't find the command in any of the menu systems.
Searched the cisco site, found this article.

I was doing that, wondering why its not working. I get all the way to the part where you do the encap but that command doesn't exist.
I powered up a 2620 that I have an it does the exact same thing. What am I missing here?
S1(config)#int fa 0/0/ .1
LS1(config-subif)#ip address 192.168.16.1 5.1 255.255.255.0
Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q, or ISL vLAN.
LS1(config-subif)#ecn nca ?
% Unrecognized command
LS1(config-subif)#enca enc ?
Interface configuration commands:
arp Set arp type (arpa, probe, snap) or timeout
backup Modify backup parameters
bandwidth Set bandwidth informational parameter
bridge-group Transparent bridging interface parameters
carrier-delay Specify delay for interface transitions
cdp CDP interface subcommands
default Set a command to its defaults
delay Specify interface throughput delay
description Interface specific description
exit Exit from interface configuration mode
ip Interface Internet Protocol config commands
llc2 LLC2 Interface Subcommands
mtu Set the interface Maximum Transmission Unit (MTU)
netbios Use a defined NETBIOS access list or enable name-caching
no Negate a command or set its defaults

Hmm that didn't copy and paste correctly. Basically there is no encapuslation command in any of the menus. I'm running IOS 12.3 and the other router I tried was 12.2.
I kept trying enca ? and it kept coming back with unrecog command.

You need an IP Plus feature set for trunking encap, do you have this feature set on your IOS?

Hmm, no idea. I'll go download an IOS Version that does have that and try it. Why would that not be a standard "feature" what good is a router if you can't encap a port and actually route vlan traffic?
Thanks for the reply. :)

That was it, I had no idea that wasn't part of a standard IOS.
Thanks!
