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.
prefix-list-
name
Enter the name of a configured IP prefix list. Routes meeting
the criteria of the IP Prefix list are leaked.
Defaults level1-into-level2 (Level 1 to Level 2 leaking is enabled.)
level2–into-level1 (Level 2 to Level 1) leaking is disabled.
