IS IS LSPDB Synch
Introduction
This is the process of synchronizing the ISIS database.
ISIS LSPDB
Newer LSPs
- Newer are accepted over older.
- On point to point links, newer LSPs are flooded periodically until they are ACKed.
- On multiaccess links, newer LSPs are flooded……(more info on the DIS interation).
Older LSPs
- IS floods the newer LSPs only to the interface that received the older LSP.
Same LSPs
- Those are ignored.
