Backbone Router Configuration
Table H-6 has been modified from the version in the book to include the IS-IS configuration exercise from the supplemental online chapter, "Configuring IS-IS Protocol." The new material has been shaded for your convenience.

Backbone_r1 Configurations
This section provides the text of the configuration files for the backbone_r1 router. The new IS-IS configuration bbr1 isis.txt has been added (see Configuration H-7), and the EIGRP configuration bbr1 eigrp.txt has been modified (see Configuration H-3).

Configuration H-3 is a modified version of the configuration that appears in the book. This Configuration H-3 replaces the Configuration H-3 in the book. Because the IS-IS configuration exercise is meant to be done before the EIGRP exercise, the router must be configured differently before EIGRP is enabled if you previously worked on the IS-IS configuration exercise. The changes to the configuration are as follows:
The IS-IS protocol, instead of the OSPF protocol, is removed from the router.
Access list 1 and route map passext are added to the router.
