Enhancing IS-IS network security
To enhance the security of an IS-IS network, you can configure IS-IS authentication. IS-IS authentication
involves neighbor relationship authentication, area authentication, and routing domain authentication.
Configuration prerequisites
Before the configuration, complete the following tasks:
• Configure network layer addresses for interfaces to ensure IP connectivity between neighboring
nodes.
• Enable IS-IS.
Configuring neighbor relationship authentication
With neighbor relationship authentication configured, an interface adds the password in the specified
mode into hello packets to the peer and checks the password in the received hello packets. If the
authentication succeeds, it forms the neighbor relationship with the peer.
Follow these guidelines when you configure neighbor relationship authentication:
• The authentication mode and password at both ends must be identical.
• The level-1 and level-2 keywords are configurable on an interface that has IS-IS enabled with the
isis enable command.
