Usage

To perform protocol-support consistency checks on hello packets, use this

Information

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).

Syntaxadvertise {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-

Enter the keywords level1-into-level2to advertise

 

 

level2

Level 1 routes into Level 2 LSPs. This setting is the default.

 

level2-into-

Enter the keywords level2-into-level1to advertise

 

level1

Level 2 inter-area routes into Level 1 LSPs. This behavior is

 

 

 

described in RFC 2966.

 

prefix-list-

Enter the name of a configured IP prefix list. Routes meeting

 

name

the criteria of the IP Prefix list are leaked.

Defaults

level1-into-level2 (Level 1 to Level 2 leaking enabled.)

Command

•

ROUTER ISIS (for IPv4)

Modes
