Usage Guidelines

Usage Scenario

A BGP-LS domain ID indicates that BGP-LS is enabled on a device. To configure a BGP-LS domain ID, run the domain identifier command. By default, a BGP router ID is used as the BGP-LS domain ID.

One BGP-LS domain ID can be configured for multiple devices so that the controller calculates routes based on the combined topology information reported by the devices.

Example

# Configure a BGP-LS domain ID (1.1.1.1).

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] link-state-family unicast
[*HUAWEI-bgp-af-ls] domain identifier 1.1.1.1
