Log-Peer-Change - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – Routing Protocol
It is recommended to configure system level when you configure IS-IS.
You can configure all the routers as either Level-1 or Level-2 if there is only one area,
because there is no need for all routers to maintain two identical databases at the
same time. You are advised to configure all routers as Level-2 in IP network so as to
facilitate extending later.
Related command: isis circuit-level.
Example
# Configure the current route to work in Level-1.
<3Com> system-view
System View: return to User View with Ctrl+Z.
