Usage
Information
The IS-IS protocol automatically determines area boundaries and are able to keep Level 1 and Level 2
routing separate. Poorly planned use of this feature may cause configuration errors, such as accidental
area partitioning.
If you are configuring only one area in your network, you do not need to run both Level 1 and Level 2
routing algorithms. You can configure the IS type as Level 1.
log-adjacency-changes
Generate a log messages for adjacency state changes.
Syntax

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
This command allows you to monitor adjacency state changes, which are useful when you monitor large
networks. Messages are logged in the system’s error message facility.
lsp-gen-interval
Set the minimum interval between successive generations of link-state packets (LSPs).
Syntax
lsp-gen-interval [level-l | level-2] interval seconds
[initial_wait_interval seconds [second_wait_interval seconds]]
To restore default values, use the no lsp-gen-interval [level-l | level-2] interval
seconds [initial_wait_interval seconds [second_wait_interval seconds]]
command.
Parameters
level-l (OPTIONAL) Enter the keywords level-1 to apply the configuration to
generation of Level-1 LSPs.
level-2 (OPTIONAL) Enter the keywords level-2 to apply the configuration to
generation of Level-2 LSPs.
interval seconds Enter the maximum number of seconds between LSP generations. The range is
from 0 to 120 seconds. The default is 5 seconds.
initial_wait_inter
val seconds
(OPTIONAL) Enter the initial wait time, in seconds, before running the first LSP
generation. The range is from 0 to 120 seconds. The default is 1 second.
second_wait_inte
rval seconds
(OPTIONAL) Enter the wait interval, in seconds, between the first and second LSP
generation. The range is from 0 to 120 seconds. The default is 5 seconds.
Defaults Refer to Parameters.
