We actively use RANCID also, but I'm not sure I'd be comfortable running
thousands of rancid 'clogin' processes to update thousands of routers :-).
However it does have some "large" users, so it's possible they use it for
this (as well as its more direct use, the config management). My own
experience with updating routers via clogin -s is that vast changes as
suggested may be slow and have other unexpected results.
however, RANCID is a very useful tool for configuration management (it
places your router configs from various vendors in a CVS tree). It provides
login programs to do this via your favourite CLI access mechanism (rcp,
telnet, ssh, whatever's supported). It's quite flexible.
For this type of application, I'd be more for what Jared Mauch suggested, a
configuration backend for partial or whole configurations (possibly using an
sql backend). A combination of WANdoc O.S., RANCID, etc, is what I'm after
(using the snmp cisco config MIB to initiate the transfers, for example).
