Hey Folks,
A big thank you for those of you that responded to my call for help. You got
me thinking, and I eventually solved my problem. Here are the events which
caused my problem and the steps I used to rectify it, for those of you that
may run into this in the future.
I downloaded a 11.3 version of IP Plus IPsec 56 IOS to the router testing
versions which would offer me the ability to configure ISL encapsulation
(VLAN routing) via subinterfaces on the Fast Ethernet ports on the 2621.
After the initial download it worked fine. However, after the first reboot
I found I could no longer see the two 10/100 interfaces any longer
ie: sh int
router>
I erased the flash and NVram to rebuild from scratch (stupid). After
erasing and reloading, the router booted into rommon. From rommon I used the
following commands to tftp the old image back into flash:
rommon 1 > tftpdnld
rommon 2 > IP_ADDRESS=148.1.1.13
rommon 3 > IP_SUBNET_MASK=255.255.255.0
rommon 4 > DEFAULT_GATEWAY=255.255.255.255
rommon 5 > TFTP_SERVER=148.1.1.2
rommon 6 > TFTP_FILE=c2600-i-mz.120-3.T3
rommon 7 > tftpdnld -r
Image was succesfully downloaded
rommon 8 > boot flash
Image booted and I was back into a working 2621. Reset the configuration
register to 0x102 and did a 'copy run start' to put the router back into its
original state.
Good learning experience. However, I am still back at my original problem of
trying to find an image that will do the ISL encapsulation on the fast
ethernet ports so I can practice some VLAN routing. The 12.1 versions of
IOS above the IP feature set require 16 flash and 40 dram, I only have 8 and
32 respectively. If anyone knows of a 12.0 version that can utilize ISL I
would appreciate you passing the image name and feature set along.
A cheap supply of 26XX memory might suffice too :-)
Cheers.

I am looking through docs to figure out my next step right now. Help
