Beware that the ENSS gated announces it's interfaces into the ANS core, even
if there are no E-BGP peers (or for that matter, even if the LAN interfaces
are down). This means that the planed test will not really idle the ENSS if:
- There are any services or *clients* on the DMZ itself
(mrouted?, DNS?, NTP?, etc)
- Anybody is remotely monitoring your peers with either snmp or ping.
My observations are based on the FDDI interface of ENSS132, which was
previously attached to a natural class C network. Physically unplugging the
FDDI did not stop the ENSS from announcing it....
Your mileage may vary.
