isis padding-hello
Function
The isis padding-hello command configures an IS-IS interface to send Hello packets with the padding field.
The undo isis padding-hello command restores the default setting.
By default, an IS-IS interface is not configured to send Hello packets with the padding field.
Usage Guidelines
The isis padding-hello and isis small-hello commands are mutually exclusive and cannot be configured on the same interface simultaneously.
If an interface that is not configured with the two commands, it sends Hello packets based on the following rules:
For a P2P interface
Before the P2P neighbor relationship is established, the P2P interface sends Hello packets with the padding field.
After the P2P neighbor relationship is established, the P2P interface sends Hello packets without the padding field.
For a broadcast interface
It sends Hello packets with the padding field.
IS-IS has been enabled on the interface using the isis enable command.
