Hello,
I've done some cisco configurations in the past without much issue.
Usually, between books and the internet, I can figure just about any
of them out.. but this one is stumping me. Perhaps there's an IOS
issue (like I have the wrong one), or perhaps it's pebkac.
I am trying to setup a sample network, or networks. I'm trying to
configure a Cisco 26xx router, with one ethernet interface, with 2 sub
interfaces on different networks (192.168.2.xx/24 and 192.168.248.xx/
24). On each of the subinterfaces I've added the router ip addresses.
On the switch (cisco 2950) I've put the port into trunk mode (same
with the main interface on the router). i've added the ports to the
appropriate vlans, but I'm getting no connectivity.
If anyone can please advise, and/or provide a link to further
resources, I would appreciate it. Here are the devices and configs:

with this setup, I cannot ping any devices on either network, and the
network cannot ping the .99 addresses assigned on the router. Please
advise. Hopefully, I'm just missing something obvious.
Thank you,

Hopefully this will give people some insight, and hopefully I won't
lose anymore hair than I already have. :P- Hide quoted text -

I don't see an IP on interface FastEthernet0/1.
Are the 192.x.x.x networks communicating?
I didn't put an IP on the fa 0/1 interface because it's "trunked", I
didn't think I needed one. On the switch itself, there is an ip of
192.168.2.10, just not an independant one one the interface itself.
All of the other 192.168.2.xx devices which are connected to the
switch are communicating, but the 192.168.2.99 interface (eth 0/0.1 on
the router) can not seem to see anything except for other addresses I
might put on the router, but it's not passing anything through the
switch.
