Question 16 🔥

Which statement is correct regarding the default MPLS TTL behavior?

Which database solution meets these requirements?

A. When an ingress edge LSR receives an IP packet, it will decrement the IP TTL field by 1; then it will set the MPLS Label TTL field to 255.

Highly voted

B. When an ingress edge LSR receives an IP packet, it will decrement the IP TTL field by 1; then it will copy the decremented IP TTL field into the MPLS Label TTL field.

Highly voted

C. When an ingress edge LSR receives an IP packet, it will just copy the IP TTL field into the MPLS Label TTL field.

Highly voted

D. When an ingress edge LSR receives an IP packet, it will copy the IP TTL field into the MPLS Label TTL field first; then it will only decrement the MPLS Label TTL field by 1.

B. They use a 127/8 address as the destination address in the MPLS echo request packet.

Highly voted

C. They use ICMP echo request and ICMP echo reply packets.

Highly voted

D. They are used to test for a broken LSP.

Highly voted

E. If there is a broken LSP, instead of using label switching, the packet can still be forwarded based on the destination IP address in the mpls ping echo request
