  1. That threw me off. Unless I’m reading it wrong, shouldn’t it be 30/120?

    Process ID 1, Router ID 3.3.3.3, Network Type NON_BROADCAST, Cost: 64
    Transmit Delay is 1 sec, State DR, Priority 1
    Designated Router (ID) 3.3.3.3, Interface address 1.1.1.2
    Backup Designated router (ID) 2.2.2.2, Interface address 1.1.1.1
    Timer intervals configured, Hello 30, Dead 120, Wait 120, Retransmit 5
    Hello due in 00:00:19
