I'm being asked to look into using BFD over our P2P transport links. Is anyone else doing this? Our transport links are all 10G Ethernet (LAN-PHY). There's no alarming inside of LAN-PHY like there is in SONET. The transport side should propagate a fiber break by stopping to send light on both ends. This is enough to cause the router interfaces to drop and for protocols to converge.
If only one strand in your fibre breaks, only the side that has the broken strand connected to Rx will see the physical interface go down. I've seen this happen with Extreme equipment at least. Best regards, -- Tore Anderson Redpill Linpro AS - http://www.redpill-linpro.com/ Tel: +47 21 54 41 27
