Explanation:
Routing Protocols on the Hierarchical Network Infrastructure The selected routing protocol should be used
based on the network design goals and the network
module being used. As shown in Figure 11-23, high-speed routing is recommended for the network core
and distribution layers. These routing protocols react fast to network changes. It is a best practice that the
same routing protocol be used in the three layers (core, distribution, access) of the enterprise network.
The enterprise edge connects the campus network with external connectivity including WAN, Internet,
VPN. remote-access modules. Routing protocols in the enterprise edge may be EIGRP, OSPF, BGP, and
static routes. Specifically in the Internet module you will find BGP/static routes.
Table 11-9 shows a summary of the recommended routing protocols in the network infrastructure.
