The Hello timer, Hello dead timer, Minimum Interval for Sending LSPs can be configured for IS-IS. You can adjust these attribute values to affect the network aggregation rate according to the actual network environment and router performance.
This describes how to set attributes such as the Link State PDUs (LSP) update period, LSP size, Mesh-Group feature, and LSP fragment extension. These attributes can be adjusted according to the actual condition of the IS-IS network.
This describes how to configure the fast flooding of the enabled LSP to affect the aggregation rate of the IS-IS network. If the Level-1 or Level-2 is not specified, the fast flooding is configured by default.
To improve the fault location efficiency on an IS-IS network and prevent SPF calculation from consuming excessive system resources, set the SPF calculation interval to a proper value.
If some IS-IS routes need to be converged by preference to minimize adverse impacts on services, configure those routes to have the highest convergence priority.
To ensure the visualization and convenience of routine maintenance and use, you can set the name of the IS-IS process for the IS-IS router, and enable the mapping between the process name and system ID.
