Method for notifying forwarding table index, node, and storage medium

A node, comprising a processor, wherein the processor is configured to, when executing a computer program, implement the following:

• determining, according to first information, a specified path-based bit indexed explicit replication-traffic engineering (BIER-TE) forwarding table index of a current node, wherein the first information comprises a sub-domain (SD) and a bit string length (BSL);
• and
• advertising the specified path-based BIER-TE forwarding table index of the current node to another node, wherein the specified path-based BIER-TE forwarding table index of the current node is encoded in a preset encoding mode.

A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when being executed by a processor, implements the following:

• determining, according to first information, a specified path-based bit indexed explicit replication-traffic engineering (BIER-TE) forwarding table index of a current node, wherein the first information comprises a sub-domain (SD) and a bit string length (BSL);
• and
• advertising the specified path-based BIER-TE forwarding table index of the current node to another node, wherein the specified path-based BIER-TE forwarding table index of the current node is encoded in a preset encoding mode.
