[nsp] bgp announcement monitoring ?

Here is the expect script I use for this :


#!/usr/bin/expect -f

#
#send_error "$argv0 [lrange $argv 0 3]\r\n"
#
#       The script uses Expect, which is a package based on Tcl.
#       You call it with the following syntax:
#
# collector route-views.oregon-ix.net NONE NONE 'route-views.oregon-ix.net>' | grep -v "^ --More-- "
# New syntax: collector <host> <usr> <pwd> <prompt when finished cmd, in ' '> <cmd to run, in ' '> <port, NO ' '>
#       The trailing grep is required to filter out the garbage
#       inserted by the console every 512 lines.  This is the bit
#       that fixed the console timeout problem, BTW.  Here's the script:
