BGP and OSPF are routing protocols used in networking. BGP has states like Idle, Connect, OpenSent, etc. OSPF has states like Down, Init, 2-Way, etc.

• BGP states: Idle, Connect, OpenSent, OpenConfirm, Established

• OSPF states: Down, Init, 2-Way, ExStart, Exchange, Loading, Full

• To configure label path in BGP, you can use the 'mpls label protocol ldp' command in Cisco IOS

• To configure BGP peering, you need to define neighbor relationships using the 'neighbor' command in BGP configur...read more

Current can be measured using an ammeter and voltage can be measured using a voltmeter.

• Use an ammeter to measure current flowing through a circuit

• Connect the ammeter in series with the circuit

• Use a voltmeter to measure the potential difference across a component

• Connect the voltmeter in parallel with the component

• Ensure proper units are used for measurement (Amps for current, Volts for voltage)
