Optimized multicast transport migration procedures

One or more non-transitory computer-readable media comprising computer-readable instructions stored thereon, wherein the computer-readable instructions, when executed by one or more processors, cause the one or more processors to:

• receive, by a first node, an advertisement indicating an advertisement transport protocol supported by a second node, wherein the first node supports a plurality of transport protocols, and the advertisement transport protocol is one of the plurality of transport protocols, wherein the first node and the second node are edge nodes of a border gateway protocol (BGP) community;
• receive, by the first node, from a requesting node through the second node a request to join the BGP community and access a resource, wherein the request includes an attribute indicating a request transport protocol supported by the requesting node, and wherein the first node and second node are part of the BGP community and the requesting node is not part of the BGP community;
• allocate, by the first node and based on the attribute, the resource for the request transport protocol supported by the requesting node;
• provide, by the first node, a notification to one or more intermediate nodes and the second node indicating allocation of the resource for the request transport protocol;
• and
• receiving, by the first node, an underlay join request for the request transport protocol enabling traffic to flow from the first node to the second node.

A system comprising:

• one or more processors;
• and
• one or more memories configured to store computer-readable instructions thereon, which when executed by the one or more processors, cause the one or more processors to:
• receive, by a first node, an advertisement indicating an advertisement transport protocol supported by a second node, wherein the first node supports a plurality of transport protocols, and the advertisement transport protocol is one of the plurality of transport protocols, wherein the first node and the second node are edge nodes of a border gateway protocol (BGP) community;
• receive, by the first node, from a requesting node through the second node a request to join the BGP community and access a resource, wherein the request includes an attribute indicating a request transport protocol supported by the requesting node, and wherein the first node and second node are part of the BGP community and the requesting node is not part of the BGP community;
• allocate, by the first node and based on the attribute, the resource for the request transport protocol supported by the requesting node;
• provide, by the first node, a notification to one or more intermediate nodes and the second node indicating allocation of the resource for the request transport protocol;
• and
• receive, by the first node, an underlay join request for the request transport protocol enabling traffic to flow from the first node to the second node.
