You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS routes are used to traverse your network. Your solution should not affect IGP routes in your route tables.
In this scenario, which traffic engineering setting will accomplish this behavior?
To ensure that MPLS routes are used to traverse the network without affecting IGP routes in the route tables, the 'mpls-forwarding' setting should be used. This configuration ensures that ingress routes are used exclusively for forwarding and not for routing, thereby not impacting the IGP routes in the route tables.
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.
i agree with you answer B
sould be answer D
