To establish a GCP session with the Cisco Smart PHY application, and later to be GCP-redirected to the appropriate CCAP Cores, the RPDs must first discover Smart PHY’s Converged Interconnect Network (CIN) virtual IP address.
Discovery is performed using DHCP. The DHCP servers assigning leases to RPDs must include the CIN virtual IP address of Cisco
Smart PHY in the suboption 61
CCAP Cores, under DHCP option 43.
To configure suboption 61
CCAP Cores under DHCP option 43, contact your DHCP software vendor.
