Exam JN0-363 topic 1 question 12 discussion

bgp—On BGP destinations only. Ingress routes are installed in the inet.3 routing table. bgp-igp—On both BGP and IGP destinations. Ingress routes are installed in the inet.0 routing table. If IGP shortcuts are enabled, the shortcut routes are automatically installed in the inet.0 routing table. bgp-igp-both-ribs—On both BGP and IGP destinations. Ingress routes are installed in the inet.0 and inet.3 routing tables. This option is used to support VPNs. mpls-forwarding—On both BGP and IGP destinations. Use ingress routes for forwarding only, not for routing.

The correct answer is B. mpls-forwarding. This setting ensures that the MPLS routes are used to traverse your network without affecting IGP routes in your route tables. It enables MPLS traffic engineering tunnels on an interface1. This is a key part of configuring MPLS Traffic Engineering (TE), which allows network operators to define how traffic flows through an MPLS core network2. The other options (A, C, and D) are related to BGP and IGP routing, not specifically to MPLS traffic engineering. Please note that actual configuration may vary depending on the specific network devices and software versions you are using. Always refer to the official documentation for your hardware and software for the most accurate information.

MPLS forwarding is the answer, it ensures it uses LSPs where applicable

The mpls-forwarding setting allows MPLS to take precedence for forwarding traffic without altering the IGP routes in the routing table.
