7.8 Configuring Static BFD for IPv4 IS-IS

BFD can provide link failure detection featuring light load and high speed (at the millisecond
level). Static BFD can be configured to monitor IS-IS links.
Context
In a static BFD session scenario, you need to configure single-hop BFD parameters, such as
local and remote discriminators and then configure the device to send BFD session setup
requests.
A static BFD session can only be established and released manually. A configuration error will
lead to a BFD failure. For example, if a local or remote discriminator is incorrectly configured,
a BFD session will not work properly.
