Usage Guidelines

Usage Scenario

If you need to enhance the system's ability to authenticate users in a bad network environment such as network congestion and improve their security, you are recommended to configure RSVP authentication enhancement.

Setting the window size to a value greater than 32 is recommended. If the size of a sliding window is small, the RSVP messages may be dropped and the RSVP neighbor relationship may be terminated.

Example

# Configure the RSVP authentication message sliding window size to be 64.
