That is completely possible.  I contend that this is *ALL* possible to
monotor via SNMP. (If you're running anything *close* to production
quality code that is.  If you're not, don't bother requesting a BGP
session with ENTERZONE!)  If you're not monitoring this, can I ask why
not?  I'm not jumping anyones case here.  I just tend to expect my peers
to take things as seriously as I do and take the same precautions.
