Hello,
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.
Since LAN-PHY doesn't have any built end-end alarming, some folks believe that
we may encounter situations where a fiber break doesn't cause interfaces do go
down. Convergence would then have to wait for IGP hellos to detect the problem.
Is anybody else running BFD over 10G LAN-PHY transport links? Any comments
around BFD for this application in general?
Thanks,
Serge
