In the VRP, which of the following authentication modes are supported by the secure shell (SSH)?

acl number 2000
rule 15 permit source 225.0.0.0 0.0.0.255

The preceding are partial router configurations. Which of the following behaviors does Ethernet
6/1/1 perform after receiving Internet Group Management Protocol Version 2 (IGMPv2) Report messages for multicast groups 225.0.0.1 and 225.0.1.1?

Exhibit:

As shown in the figure, RTA connects to RTB and RTC A TE tunnel is configure on RTA to reach RTC. The TE tunnel cannot be successfully established. However, CSPF-based calculation is successful and RTA does not receives any PathErro messages. What are possible causes?

The Huawei router is the last hop DR where the SSM Mapping function is enabled at the interface.
Some IGMPv2 hosts expect to receive (1.0.0.1, 232.1.0.1), (1.0.0.1, 232.1.0.2), and (2.0.0.1,
232.1.3.2) dat
a. How can you satisfy the preceding requirements with the least configurations?

Refer to the exhibit.

As shown in the figure, CE 1 and CE 2 belong to VPN A, both LDP and
TE tunnels are configured between PE 1 and PE 2, the QPPB feature is configured on PE 2, and a tunnel policy is configured and applied to VPNs under PE 2 to make TE tunnels be preferred.
11.11.11.11/32 is a static route on CE 1 and is learned by CE 2. CE 2, however, fails to apply resource isolation VPN to PE 2. What is the possible cause?
