[RFC7880] defines a simplified mechanism for using Bidirectional Forwarding Detection (BFD) [RFC5880]. This mechanism depends on network nodes knowing the BFD Discriminators that each node in the network has reserved for this purpose. The use of the Intermediate System to Intermediate System (IS-IS) [IS-IS] protocol is one possible means of advertising these discriminators.
