B.

C.
Provides for connectivity in both the data center and other areas and services within the
network
D.
Defines a summarization boundary for network control plane protocols
Explanation:
The distribution layer in the campus design has a unique role in that it acts as a services and
control boundary between the access and the core. It defines a summarization boundary for
network control plane protocols (EIGRP, OSPF, Spanning Tree) and serves as the policyboundary
between the devices and data flows within the access-distribution block and the rest of the
network. In providing all these functions the distribution layer participates in both the accessdistribution block and the core.
