Configuring IS-IS Interface Parameters
Purpose
(Optional) Sets the router to log IS-IS adjacency state changes.
Enter all to include all changes generated by events that are
not related to the Intermediate System-to-Intermediate System
Hellos, including End System-to-Intermediate System PDUs
and link state packets (LSPs).
(Optional) Specifies the maximum LSP packet size in bytes.
The range is 128 to 4352; the default is 1497 bytes.
If any link in the network has a reduced MTU size,
Note
you must change the LSP MTU size on all routers in
the network.
(Optional) Causes an IS-IS Level 1-2 border router to stop
advertising the Level 1 area prefix into the Level 2 backbone
when full connectivity is lost among the border router, all
adjacent level 1 routers, and end hosts.
Returns to privileged EXEC mode.
(Optional) Saves your entries in the configuration file.
