Silly question perhaps, but why would you do BFD on dark fiber?
Because Ethernet lacks the PRDI that real WAN protocols have. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE SA0XLR +46 705 989668 If I am elected no one will ever have to do their laundry again! PS: Don't get me wrong. I'm all for Ethernet, it is cheap (or perhaps, SDH/SONET line cards were artificially expensive) and it makes networks faster more often, by virtue of interface cheapness. But one really needs to tack about half the signalling from SDH onto Ethernet (here, BFD) to get some predictability from it. Which is OK, it was made for NFS and Telnet on a LAN. It does really well considering that.
