With regard to using Cisco routers for integration into the AMPRNET, if
you are going to load full tunnels be ready to throw some descent
hardware at the task. The first issue is the config length, you need
config compression on and no less than a 2600 due to nvram size. The
other issue is number of interfaces, you also need at least a 2600 to
configure the number of tunnels needed to be fully meshed. I am
currently running a 2651xm and it does an ok job. Let me know if you are
interested in a script to convert the encap.txt into a loadable config.
