>If there is a catastrophic failure tomorrow morning, Merit >will advise the ANS NOC to roll back to the previous configuration >(the one installed on Tuesday morning). Which Tuesday? 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. Good luck, --MM--
