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

The leaf node is not configured for the family evpn NLRI (D):

The exhibit shows that there is an unsupported capability NP error for AFI 1, SAFI 70. This indicates that the leaf node is not configured to support the EVPN (Ethernet VPN) address family.

The BGP configuration and troubleshooting details can be found in "Juniper Commands.pdf" and related EVPN configuration documents​​​​.

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.

Understanding Multicast Listener Registration Protocols:

Multicast listener registration protocols are used to manage multicast group memberships on a network.

They allow devices to join or leave multicast groups dynamically.

Protocols Supported by Junos:

MLD (Multicast Listener Discovery):

Used for IPv6 multicast group management. It is the IPv6 equivalent of IGMP.

MLD allows routers to discover multicast listeners on a network.

IGMP (Internet Group Management Protocol):

Used for IPv4 multicast group management.

IGMP enables hosts to join and leave multicast groups and allows routers to manage multicast group memberships.

Verification and Configuration in Junos:

MLD and IGMP are supported on Juniper devices running the Junos operating system.

Configuration examples:

IGMP:

shell

Copy code

set protocols igmp interface ge-0/0/1.0

MLD:

shell

Copy code

set protocols mld interface ge-0/0/1.0
