LSP packet format
The Link State PDUs (LSP) carry link state information. LSP involves two types: Level-1 LSP and
Level-2 LSP. The Level-2 LSPs are sent by the Level-2 routers, and the Level-1 LSPs are sent by the
Level-1 routers. The level-1-2 router can send both types of LSPs.
The two types of LSPs have the same format, as shown in
