JN0-363 Exam Questions & Answers

The IPv6 header includes a new field that is not found in the IPv4 header, called the flow label. The flow label in IPv6 is used to identify packets that require special handling by routers for quality of service (QoS) or other reasons, allowing these packets to be handled efficiently as they move through the network.

The policy statement shown in the exhibit has a term that specifies load-balance per-packet, which indicates that per-packet load balancing is being used. This means that the routing device will distribute packets out multiple paths on a per-packet basis, rather than on a per-flow (per-destination or per-source-destination pair) basis.

The show bgp neighbor command in Junos OS provides a detailed description of each BGP session, including session state, options configured, and counters for messages sent and received. This is the command you would use to see a detailed list of all established BGP sessions.

An Integrated Routing and Bridging (IRB) interface is used to provide Layer 3 routing services to hosts within a bridge domain. The IRB acts as a default gateway for hosts in that domain, enabling communication with other networks.

By default, BGP will propagate routes learned from EBGP peers to other IBGP peers. However, due to the BGP split-horizon rule, routes learned from one IBGP peer are not re-advertised to another IBGP peer. This behavior is designed to prevent routing information loops within the same AS.
