What is the role of a fusion router in an SD-Access solution?

• A. acts as a DNS server
• B. provides additional forwarding capacity to the fabric
• C. performs route leaking between user-defined virtual networks and shared services
• D. provides connectivity to external networks

Explanation: Today the Dynamic Network Architecture Software Defined Access (DNA-SDA) solution requires a fusion router to perform VRF route leaking between user VRFs and Shared-Services, which may be in the Global routing table (GRT) or another VRF. Shared Services may consist of DHCP, Domain Name System (DNS), Network Time Protocol (NTP), Wireless LAN Controller (WLC), Identity Services Engine (ISE), DNAC components which must be made available to other virtual networks (VN’s) in the Campus.
