Will lowering the carrier-delay on an interface configuration interfere with using BFD on the same interface?
If I configure
carrier-delay msec 0 on an Ethernet interface the RIB is automatically notified of the physical link down event. In a scenario where the physical link doesn't go down but communications are not traversing the link (3rd party DWDM lamda for example) BFD would detect this.
Are there dangers to using a low carrier delay value with BFD, or is it recommended? Or will one simply superseed the other from a configuration perspective?
I would be using them in conjunction with interaface dampening and
ip routing protocol purge interface in global configuration.
