Well, I don't have a concrete example, but it seems to me a simple loop
would do the trick.
set s [snmp session]
foreach router {ip1 ip2 ip3 ip4 ... ipn} {
$s configure -address $router
# You may need to modify the below line
# I'm not sure a community failure would trigger a catch, but
# I would think so
catch {$s set $oid} err
}
Now, say you want to do multiple community strings.
There are a couple of ways that I'd think about doing it (off the top of my head)
1) have an associative array of community strings indexed by IP address
e.g. $s configure -address $router -community $ctable($router)
2) supply community strings to foreach loop
e.g.
foreach router {{ip1 setme} {ip2 rwcommunity} {ip3 othercommunity}} {
$configure -address [lindex $router 0] -community [lindex $router 1]
...
}
This just requires scotty, it's quick, it's easy, and you can set it up
to read from files if you want.
