4.11 Improving Security of an OSPF Network
On a network demanding high security, you can adopt the GTSM mechanism and configure
OSPF authentication to improve the security of the OSPF network.
4.11.1 Establishing the Configuration Task
Before improving the security of an OSPF network, familiarize yourself with the applicable
environment, complete pre-configuration tasks, and obtain the required data. This can help you
complete the configuration task quickly and accurately.
Applicable Environment
In a network demanding high security, you can configure OSPF authentication and adopt the
GTSM mechanism to improve the security of the OSPF network.
