In the switching network as shown in the figure, all three switches only have the default VLAN1, the interconnection ports of the three switches are trunks, and all VLANs are allowed to pass, and the three switches have the global and port GVRP functions enabled. VLAN 10 is created on the switch SWA, VLAN 20 is created on the switch SWC, and the GVRP registration mode of the Ethernet 1/0/1 port is set to Fixed on the switch SWA, and the display vlan command is executed on the SWB to view the VLAN existing on VLASWB ( Select one or more)

The two routers are connected through a LAN to form a VRRP backup group. The configuration on each interface is as follows:
[RTA-GigabitEthernet1/0] display this
ip address 192.168.0.252 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.1.254
vrrp vrid 1 priority 120
[RTB-GigabitEthernet1/0] display this
ip address 192.168.0.253 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.1.254
It can be known from the above information

In the switching network as shown in the figure, VLAN10 is set as SuperVLAN on the switch SWA, and VLAN2 and VLAN3 are Sub VLANs of VLAN10. If PCA and PCB can communicate with each other, which of the following items should be included in the configuration on the switch SWA?

The following statements about BSR and RP in PIMSM are correct (choose one or more)

The following are the functions of the access layer (choose one or more)
