IPV4-LSP-IDENTIFIERS TLV draft-ietf-pce-stateful-pce-11. Encoding: TLV Type: 18 (non standard) Whenever the value of an LSP identifier changes, a PCC MUST send out an LSP State Report, where the LSP Object carries the LSP Identifiers TLV that contains the new value. The LSP Identifiers TLV MUST also be included in the LSP object during state synchronization. There are two LSP Identifiers TLVs, one for IPv4 and one for IPv6. The format of the IPV4-LSP-IDENTIFIERS TLV is shown in the following figure: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type=[TBD] | Length=12 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | IPv4 Tunnel Sender Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | LSP ID | Tunnel ID | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Extended Tunnel ID | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Figure 18: IPV4-LSP-IDENTIFIERS TLV format The type of the TLV is [TBD] and it has a fixed length of 12 octets. The value contains the following fields: IPv4 Tunnel Sender Address: contains the sender node's IPv4 address, as defined in [RFC3209], Section 4.6.2.1 for the LSP_TUNNEL_IPv4 Sender Template Object. LSP ID: contains the 16-bit 'LSP ID' identifier defined in [RFC3209], Section 4.6.2.1 for the LSP_TUNNEL_IPv4 Sender Template Object. Tunnel ID: contains the 16-bit 'Tunnel ID' identifier defined in [RFC3209], Section 4.6.1.1 for the LSP_TUNNEL_IPv4 Session Object. Tunnel ID remains constant over the life time of a tunnel. However, when Global Path Protection or Global Default Restoration is used, both the primary and secondary LSPs have their own Tunnel IDs. A PCC will report a change in Tunnel ID when traffic switches over from primary LSP to secondary LSP (or vice versa). Extended Tunnel ID: contains the 32-bit 'Extended Tunnel ID' identifier defined in [RFC3209], Section 4.6.1.1 for the LSP_TUNNEL_IPv4 Session Object.
