SD-WAN Virtual Connection (SWVC) Reserved Prefixes Service Attribute

The SWVC Reserved Prefixes Service Attribute specifies a list of IP Prefixes that the Service Provider reserves for use for the SWVC within their own network or for distribution to the Subscriber via DHCP or SLAAC. Addresses in these prefixes may be exposed to the Subscriber, for example for diagnostics purposes. The list can be empty or can contain IPv4 or IPv6 Prefixes or both. These IP Prefixes need to be agreed upon so as to ensure they do not overlap with IP Prefixes assigned by the Subscriber inside the Subscriber Network.

[R16] The Service Provider MUST identify IP Prefixes that are reserved in the SWVC and cannot be assigned by the Subscriber.

Note that it is not necessary to reserve the Service Provider’s IP address on the directly connected subnet for a UNI using this attribute; such addresses are automatically reserved. See sections 10.4 and 10.5.
