Intermediate System to Intermediate System (IS-IS) | 809
is-type
e
Configure IS-IS operating level for a router.
Syntax
is-type {level-1 | level-1-2 | level-2-only}
To return to the default values, enter no is-type.
Parameters
Defaults
level-1-2
Command Modes
ROUTER ISIS
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. The IS type can be configured as Level 1.
log-adjacency-changes
e
Generate a log messages for adjacency state changes.
Syntax
log-adjacency-changes
To disable this function, enter no log-adjacency-changes.
Defaults
Adjacency changes are not logged.
Command Modes
ROUTER ISIS
Usage
Information
This command enables you to monitor adjacency state changes, which is useful when you monitor
large networks. Messages are logged in the system error message facility.
lsp-gen-interval
e
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.
level-1
