Usage Information To perform protocol-support consistency checks on hello packets, use this command.
The adjacency-check is enabled by default.
If a BFD session goes down indicating that IPv4 or IPv6 connectivity to its neighbor is
lost, it does not imply that the adjacency is lost altogether. The hello adjacency runs
over Layer 2, and does not require IP connectivity. However, if IPv4 connectivity is lost
to a neighbor, then when the next SPF calculation is performed, the system ensures
that it does not calculate any IPv4 or IPv6 routes through that neighbor.
