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.
advertise
Leak routes between levels (distribute IP prefixes between Level 1 and Level 2 and vice versa).
Syntax
advertise {level1-into-level2 | level2-into-level1}
prefix-list-name
To return to the default, use the
no advertise {level1-into-level2 | level2-into-level1}
[
prefix-list-name
]
command.
Parameters
level1-into-level2
Enter the keywords
level1-into-level2
to advertise Level 1 routes into Level 2
LSPs. This setting is the default.
level2-into-level1
Enter the keywords
level2-into-level1
to advertise Level 2 inter-area routes into
Level 1 LSPs. This behavior is described in RFC 2966.
