Configuring Bgp Ls; Configuring Basic Bgp Ls; Configuring Bgp Ls Route Reflection - HP FlexFabric 12900E Series Configuration Manual

Configuring BGP LS

The BGP Link State (LS) feature implements inter-domain and inter-AS advertisement of link state
database (LSDB) and TE database (TEDB) information.
The device sends the collected link state information to the controller, which implements end-to-end
traffic management and scheduling, and meets the requirements of intended applications.

Configuring basic BGP LS

Step
1. Enter system view.
2. Enter BGP instance view.
3. Specify an AS number for
an LS peer or peer group.
4. Create
address family and enter its
view.
5. Enable
exchange LS information
with the peer or peer group.

Configuring BGP LS route reflection

Perform this task to configure a BGP route reflector and its clients. The route reflector and its clients
automatically form a cluster identified by the router ID of the route reflector. The route reflector
forwards route updates among its clients.
To configure BGP LS route reflection:
Step
1. Enter system view.
2. Enter BGP instance view.
3. Enter BGP LS address
family view.
4. Configure the device as a
route reflector and specify
a peer or peer group as its
client.
5. Enable
between clients.
6. (Optional.) Configure the
cluster ID of the route
reflector.
