Abstract

See full text

According to an embodiment, a node comprises one or more processors operable to execute instructions to cause the node to perform operations that comprise receiving a packet from a first node associated with an SD-WAN domain. The packet comprises a header indicating a TLOC associated with a second node to send the packet, the second node associated with an SR domain. The operations comprise determining that the TLOC corresponds to a virtual TLOC used in the SD-WAN domain to identify the second node that is in the SR domain and, in response, determining a second node identifier used in the SR domain to identify the second node. The operations further comprise preparing the packet to be communicated via the SR domain. Preparing the packet comprises including the second node identifier in the packet. The operations further comprise sending the packet comprising the second node identifier to the second node.
