Refer to the exhibit.
The red dashed lines represent the preferred paths for the MPLS TE tunnel 1 and MPLS TE tunnel 2 to reach RTE3. The black dotted lines are the less desirable path
In case RTA or RTD fails, the MPLS TE tunnel 1 and MPLS TE tunnel 2 preempt the MPLS TE tunnel 3. This causes a lack of the MPLS connectivity from CRS3
Which solution avoids the MPLS TE tunnel 3 to be teardown by the MPLS TE tunnel 1 and MPLS TE tunnel 2?
A . change the MPLS TE tunnel 3 priority values to 6 4
B . lower the signaled-bandwidth value of the MPLS TE tunnel 3
C . use the exclude option on the explicit path configuration for the MPLS TE tunnel 1 and MPLS TE tunnel 2
D . change the MPLS TE tunnel 3 priority values to 4 6
E . use affinity and link coloring in all MPLS TE tunnels and MPLS TE link resources
Answer: A
