Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?
A. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
B. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
C. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
D. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.
DHCP Option 82 will be utilized by FEN when the relay agent is enabled. There is no explicit command to enable this option. In addition to this, there is no “circuit IP” information, right term would be “circuit ID”.
