According to this picture, what can we judge? (Multiple choice)

IS-IS supports multi-instance and multi-process, that is, on an IS-IS router. You can configure multiple VPN instances to be associated with multiple IS-IS processes.
Which of the following descriptions about IS-IS multi-instance and multi-process are correct? (Multiple choice)

The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.

IS-IS is a link state routing protocol that uses the SPF algorithm for routing calculations. A park has deployed IPv4 and IPv6 at the same time and runs IS-IS to achieve network interconnection. As shown in the figure, the network IPv4 and IPv6 have the same overhead, and R1 and R4 only support IPv4. By default, in the calculated IPv6 shortest path tree, the next hop device for R2 to access R6 is () (Note: The device name must be consistent with the figure, such as: R1)
