CCIE Practice Lab:

Prestaging: Backbone Router Configuration

Configure R6 as a backbone router. Configure R6 as an external BGP peer to R1's IP address of 160.100.2.1 and R7's IP address of 160.100.1.1. Use 2001 as the Autonomous System ID for this router. Configure loopback interfaces on this router with the following addresses:

160.100.100.1/24

197.192.100.1/24

197.192.101.1/24

197.192.102.1/24

Use the network command to circulate the networks. Example 18-4 illustrates the configuration of the backbone router R6.

The following portion of the lab is timed and should begin after the configuration and physical installation of the Frame Relay switch and the backbone router. Do not configure any other routers at this time.
