Usage Guidelines

Usage Scenario

After the stub-router command is configured on the device, the device instructs other devices not to forward data to itself by increasing the cost to the maximum value (65535) for the links in the device-LSA generated by the device. The cost is not infinite, and therefore, the routes to this stub device still exist.

Example

# Configure a stub device to advertise external-LSAs and inter-area-prefix-LSAs with cost 16777214.
