2600 subinterface problem

netstat

hey ppl,

i'm currently playing around with a 2600, 2950 and a 3550. I have a problem with the setting up on the 2600 subinterface. all i want to do is create a router on a stick with the 2600, with 2950 as a vtp server, 3550 vtp client. My problem is that the subinterface of the 2600 is not letting me config the ip address nor the encapsulation. I was told at work that the 2600 wants to be configured as a trunk before it will accept those configs, and i am missing a command to do so. Usually, it is enough to enter the sub interface command, place encapsulation dot1q 3 etc and ip address, and that sub interface becomes a trunk! (works on simulators!) but not in this case! btw iso ver is 12.3!


Router#
Router#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int eth0/0.1
Router(config-subif)#ip address 192.168.2.1 255.255.255.0


% 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.

Router(config-subif)#encapsulation dot1q 2
^
% Invalid input detected at '^' marker.

Router(config-subif)#


Any ideas which config am i missing? or maybe a link to the solution?

thanks!

although you're running 12.3 you don't seem to have 802.1q trunking as an option.
try the the ios "feature navigator"

i would suggest using 12.2(29) if u can get the enterprise version otherwise to use 12.3 u will have to use c2600-ik9o3s3-mz.123-15 in order to use the sub interfaces on fa0/0.. this was learned from experience

that's interesting

it's t-train in 12.1 and 12.2 and doesn't appear in 12.3.
it seems it has been surpassed (or deprecated) by that fact you can route vlans on the 3550,3750 platforms.
