In this critical session, we examine BGP in great detail, among other topics! Students are presented with lab configuration and written exam challenges. Here is a sample written exam challenge from this exciting course for our blog readers.

b. In order to view the “topology table” for BGP, use show ip bgp
c. The LOCAL_PREF attribute is optional in BGP updates
d. If a prefix was learned via redistribution, it possesses the IGP ORIGIN code
e. If an advertising router and a receiving router are internal peers and the NLRI of the update refers to a destination in a different AS, the NEXT_HOP is the IP address of the external peer from which the route was learned
f. If an advertising router and a receiving router are internal peers and the NLRI of the update refers to a destination in a different AS, the NEXT_HOP is the IP address of the internal peer from which the route was learned
