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.
Command Modes
● ROUTER ISIS (for IPv4)
● CONFIGURATION-ROUTER-ISIS-ADDRESS-FAMILY-IPV6 (for IPv6)
