In a Cisco SD-WAN network, which VPN Identifier is reserved for carrying out-of-band network management traffic?
VPN 512 is reserved for carrying out-of-band network management traffic in a Cisco SD-WAN network. This specific VPN is utilized for the management and communication of the Viptela devices within the overlay network, ensuring that all management traffic is segregated from data plane traffic and handled appropriately.
VPN 0—Transport VPN, which carries control traffic via the configured WAN transport interfaces. Initially, VPN 0 contains all of a device's interfaces except for the management interface, and all interfaces are disabled. VPN 512—Management VPN, which carries out-of-band network management traffic among the Viptela devices in the overlay network. The interface used for management traffic resides in VPN 512. By default, VPN 512 is configured and enabled on all vEdge routers except for vEdge 100. For controller devices, by default, VPN 512 is not configured. VPNs 1 through 511, and 513 through 65530—VPNs on vEdge routers for service-side data traffic. https://www.cisco.com/c/en/us/support/docs/routers/12000-series-routers/47321-ciscoef.html
