snapshot of what i’m studying this days:
“Step 5. Routers exchange DBDs listing the LSAs in their LSD by RID and sequence number.
Step 6. Each router compares the DBD received to the contents of its LSDB. It then sends a LSR for missing or oudated LSAs. Each router responds to its neighbor’s LSR with a LSU. Each LSU receives an ACK.“
sigh. could be worse… right?
