Well, I recall a certain 7507 many years ago that randomly flooded the peering exchange necessitating the MAC lock down. The actual number, perhaps Dylan can answer that. -----Original Message----- From: Mark Frater Sent: Wednesday, October 03, 2012 4:09 PM To: nznog(a)list.waikato.ac.nz Subject: [nznog] FW: APE MAC addresses Anyone know what the rational is around the "official policy around APE" of only having a single MAC address per port? I would have thought that there was some technical merit in allowing at least 2 to cover rotuer replacement (without MAC address spoofing) and offer some peer router diversity options (e.g. either via separate peering sessions or VRRP implementation.)
