Authentication Sequence: [ 0 ]
Router ID: 3.3.3.3 Address: 192.168.1.3 GR State: Normal
State: Full Mode: Nbr is Slave Priority: 2

The output shows that Firewall becomes the DR and Router B becomes the BDR.
The full neighbor state means an adjacency has been established. The 2-way neighbor state
means the two routers are not the DR or BDR, and they do not exchange LSAs.
