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 enhancing IS-IS network security, complete the following tasks:
•
Configure network layer addresses for interfaces to make neighboring nodes accessible to each
other at the network layer.
•
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.
The authentication mode and password at both ends must be identical.
Follow these steps to configure neighbor relationship authentication:
