Point-to-multipoint transport chain

A network node, comprising:

• one or more memories;
• and
• one or more processors to:
• receive a packet that originated from a root network node;
• process the packet to determine segment identifier (SID) information associated with a point-to-multipoint transport chain;
• determine, based on the SID information, that the network node is a tail-end leaf node in the point-to-multipoint transport chain,
• wherein the network node is configured to concurrently handle different types of segment routing packets;
• and
• process the packet to perform one or more actions,
• wherein the one or more actions comprise:
• causing one or more settings of the network node to be adjusted.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of network node, cause the one or more processors to:
• receive a first packet;
• process the first packet to determine segment identifier (SID) information associated with a first point-to-multipoint transport chain,
• wherein the network node is configured to handle different types of segment routing packets;
• determine, based on the SID information associated with the first point-to-multipoint transport chain, that the network node is a transit leaf node in the first point-to-multipoint transport chain;
• generate, based on determining that the network node is a transit leaf node in the first point-to-multipoint transport chain, a copy of the first packet,
• wherein the network node processes the copy of the first packet and forwards the first packet to another network node;
• process the copy of the first packet to perform one or more actions,
• wherein the one or more actions include causing one or more settings of the network node to be adjusted;
• send, based on determining that the network node is a transit leaf node in the first point-to-multipoint transport chain, the first packet to the other network node;
• receive a second packet;
• process the second packet to determine SID information associated with a second point-to-multipoint transport chain;
• determine, based on the SID information associated with the second point-to-multipoint transport chain, that the network node is a tail-end leaf node in the second point-to-multipoint transport chain;
• and
• process the second packet to perform one or more additional actions.
