13.2.2 Configuration flow

1. Configure the IPv4 interfaces in advance.

2. Set the address of the local device in the loopback interface in advance.

3. Configure the BGP4 peers.

4. Set the BGP4 route learning policy.

5. Set the BGP4 route advertising policy.

6. Configure learned route filtering.

7. Configure advertised route filtering.

8. Set the learned route filter conditions.

9. Set the advertised route filter conditions.

10. Apply the filters to BGP4+ operation.

Notes

If you set up BGP4 peering without first configuring the route filters, the Switch will begin performing route learning and advertising as soon as the peer relations are established. To prevent unintended route learning and advertising, first set the disable configuration command to disable BGP4 operation, and then set the neighbor remote-as configuration command. To start BGP4 after configuring the route filters, use the no form of the disable configuration command.
