In PIM DM, which of the following statements about state-refresh message processing are true?
As shown in the figure, the costs of paths from RTA to RT 11, RT 12, RT
13, RT 14, and RT 15 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RTB to RT 31, RT 32, RT 33, RT 34, and RT 35 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RT 11 to RT 21 and from RT 21 to RT 31 are both 5. The available bandwidth is 200 Mbit/s.
The cost of the path from RT 12 to RT 32 is 5 and the available bandwidth is 120 Mbit/s. The cost of the path from RT 13 to RT 33 is 10 and the available bandwidth is 80 Mbit/s.
The cost of the path from RT 14 to RT 34 is 10 and the available bandwidth is 100 Mbit/s.
The cost of the path from RT 15 to RT 35 is 10 and the available bandwidth is 100 Mbit/s.
The load balancing rule of Constraint Shortest Path First (CSPF) is set to Random on RTA.
Which path will a 100 Mbit/s tunnel from RTA to RTB take?
Exhibit:
As shown in the figure, Super VLAN is enabled on SWA (a LAN switch). The Super VLAN configuration is as follows:
Which of the following specifics the time order in which the preceding debugging information is generated?
Refer to the exhibit.
This figure shows the MPLS L3VPN networking. CE 1 and CE 3 belong to VPN A.
CE 2 and CE 4 belong to VPN B.
Two MPLS TE tunnels (5 Mbit/s and 10 Mbit/s) and an LSP tunnel are set up between PE 1 and PE 2.It is expected that a tunnel policy is configured on PE
1 to distribute traffic in the three tunnels and MPLS TE tunnels are preferred. Configurations on PE

returnUnder the preceding configurations, traffic cannot be distributed to the three tunnels. To implement load balancing, which of the following modifications are correct?
