Use the VPN template for all Cisco SD-WAN devices running the Cisco SD-WAN software. If the IP address of the interface conflicts with the system IP address of Cisco vManage instance, it can break the NETCONF session and lead Cisco vManage to read the device as offline. Example of a sequential numbering schemes is 172.16.1.1, 172.16.1.2, 172.16.1.3, and so on.Įnsure that any network interface configured on a device has a unique IP address. To maximize the efficiency of the load-balancing among Cisco vSmart Controllers, use sequential numbers when assigning system IP addresses to the Cisco vEdge device s in the domain. This number includes physical interfaces, loopback interfaces, and subinterfaces. You can configure up to 512 interfaces on a Cisco vEdge device. In practice, you always configure additional parameters for each interface. Each interface can be present only in a single VPN.Īt a high level, for an interface to be operational, you must configure an IP address for the interface and mark it as operational The interfaces that participate in a VPN are configured andĮnabled in that VPN. In the Cisco SD-WAN overlay network design, interfaces are associated with VPNs.
