Prestaging: Backbone Router Configuration

Configure R7 as a backbone router. Configure R7 as an external BGP peer to R2's IP address of 192.128.128.2/24. Use 2010 as the Autonomous System ID for this router. Configure loopback interfaces on this router with the following addresses:

128.200.1.1/24

128.201.1.1/24

128.202.1.1/24

Use the network command to circulate the networks. Example 18-2 illustrates the configuration of the backbone router R7.

The following portion of the lab is timed, and it should begin after the configuration and physical installation of the Frame Relay switch and the backbone router.
