A packet enters a Junos device. No matching destination entry exists in the forwarding table.
How will the device respond?
A packet enters a Junos device. No matching destination entry exists in the forwarding table.
How will the device respond?
When a packet enters a Junos device and no matching destination entry exists in the forwarding table, the Packet Forwarding Engine (PFE) responds to the source with a destination unreachable notification message. This is because the PFE is responsible for the forwarding and processing of packets, including generating ICMP error messages like destination unreachable.
D: ICMP messages are sent to the packet’s source to report various error conditions and to respond to ping requests. Examples of ICMP errors include destination unreachable messages, which are sent when no entry is present in the forwarding table for the packet’s destination address, and time-to-live (TTL) expired messages, which are sent when a packet’s TTL is decremented to zero. In most cases, the PFE process handles the generation of ICMP messages.
Pretty Sure D is the answer here.
D is the Correct answer. According to Voucher assessment Test of Juniper. D. The PFE responds to the source with a destination unreachable notification message.
B is the correct answer. Destination unreachables are handled by the RE. Along with TTL expired.
B is the correct answer PFE process only handles the generation of ICMP messages, but the decision is made by RE.
Im guessing you failed your JNCIA?
Destination unreachables are handled by the RE.
Absolutely D
