To calculate routes, nodes need a view of the network topology. This is achieved via a **Neighbor List** extension to the `IdentityAnnouncement` packet. To calculate routes, nodes need a view of the network topology. This is achieved via a **Neighbor List** extension to the `IdentityAnnouncement` packet.
* **Mechanism:** `IdentityAnnouncement` packets contain a TLV (Type-Length-Value) payload. The `ANNOUNCE` packet payload now consists of a sequence of TLVs. The standard identity information is followed by an optional Gossip TLV.
* **Mechanism:** Appended to the `IdentityAnnouncement` payload.
* **New TLV Type:** `0x04` (Direct Neighbors). * **New TLV Type:** `0x04` (Direct Neighbors).
* **Content:** A list of Peer IDs that the announcing node is directly connected to. * **Content:** A list of Peer IDs that the announcing node is directly connected to.
**TLV Structure (Type 0x04):** **TLV Structure (Type 0x04):**
```text ```text
[Type: 0x04] [Length: 1B] [Count: 1B] [NeighborID1 (8B)] [NeighborID2 (8B)] ... [Type: 0x04] [Length: 1B] [NeighborID1 (8B)] [NeighborID2 (8B)] ...
``` ```
The `Length` field indicates the total size of the neighbor IDs in bytes (N * 8). There is no explicit count field.
Nodes receiving this TLV update their local mesh graph, linking the sender to the listed neighbors. Nodes receiving this TLV update their local mesh graph, linking the sender to the listed neighbors.
