Refer to the diagram above, which of the following statement about the unlimited dynamic bandwidth mode is correct? (Multiple choice)

When the path from RT1 to RT3 fails, the main tunnel 1 has no way to go, so the backup path of tunnel 1 restores 600M bandwidth. Since 50OM bandwidth has been occupied by tunnel 2, the remaining bandwidth of the 1G link is only 500M, and tunnel 1 takes priority. The level is higher than tunnel 2, so insufficient bandwidth can be preempted from tunnel 2. The backup path of tunnel 1 restores 60OM bandwidth, and tunnel 2 uses the remaining 40OM bandwidth.

The unlimited dynamic bandwidth mechanism is as follows: 1. When both the main and backup paths of the tunnel are up, only the main path will deduct the bandwidth, and the backup path will not deduct the bandwidth; 2. When the main path fails and there is no way to go, the link passed by the backup path will Deduct the bandwidth; 3. After the main path is restored, deduct the bandwidth from the main path again, and release the bandwidth from the backup path.

In the unlimited dynamic bandwidth mode, when the main path of tunnel 1 is up, the backup path does not deduct bandwidth, so the main path of tunnel 2 is on RTI-RT2-RT4-RT3. Because the backup path of tunnel 1 does not deduct bandwidth, the tunnel 2 considers that the available bandwidth of this path is 1G; the backup path of tunnel 2 is on RT1-RT3. Because the backup path of tunnel 2 does not deduct bandwidth, and the remaining available bandwidth on the RT1-RT3 link is 4OOM, the path calculation can be successful.

In the unlimited dynamic bandwidth mode, when both the primary and backup paths of the tunnel are up, the backup path will not deduct bandwidth directly.
