JN0-649 Exam Dumps : Enterprise Routing and Switching Professional (JNCIP-ENT)

Enabling LLDP-MED:

LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery) is an extension of LLDP specifically for VoIP devices.

It allows network devices to advertise and receive configuration information, such as VLAN IDs, from the network switch.

Voice VLAN Feature:

The voice VLAN feature on switches is designed to simplify the deployment of VoIP by automatically placing voice traffic on a designated VLAN.

Configuring the appropriate access interfaces and VLAN ID for voice traffic ensures that voice packets are prioritized and properly segmented from other types of traffic.

Configuration Steps:

Enable LLDP-MED on the appropriate access interfaces:

plaintext

Copy code

set protocols lldp-med interface ge-0/0/0

Enable the voice VLAN feature and specify the VLAN ID:

plaintext

Copy code

set ethernet-switching-options voip interface ge-0/0/0 vlan voice

set ethernet-switching-options voip interface ge-0/0/0 forwarding-class assured-forwarding

When two BGP routes have identical attributes (MED, origin, AS path length, local preference), BGP uses the router ID as a tie-breaker. In this case, route 2 has a higher router ID (10.10.200.1 vs. 10.10.100.1). BGP will select the route with the higher router ID as the active route.
