The WAN link between the two routers MSR-1 and MSR-2 uses the PPP protocol. The two ends learn each other's routes by configuring RIP. Currently, the route learning is normal. Now the following commands are added to the RIP configuration of MSR-1:
[MSR-1-rip-1] silent-interface all
So ______ . (Multiple choice)

• A.After configuring this command, the RIP route in the MSR-1 routing table disappears immediately
• B.This command makes all interfaces of MSR-1 only send routing updates and not accept routing updates
• C.After configuring this command, the RIP route in the MSR-2 routing table disappears immediately
• D.This command makes all interfaces of MSR-1 only receive routing updates without sending routing updates

The WAN link between the only two routers MSR-1 and MSR-2 in the customer network adopts the PPP protocol, and the two ends learn each other's routes by configuring RIP. Currently, the route learning is normal, and now it is in the RIP of MSR-1. The following commands are added to the configuration:
[MSR-1-rip-1] silent-interface all
So ______ . (Multiple choice)

• A.10 minutes after configuring this command, the RIP route in the MSR-1 routing table disappears
• B.10 minutes after configuring this command, the RIP route in the MSR-2 routing table disappears
• C.This command makes all interfaces of MSR-1 only send routing updates and not accept routing updates
• D.This command makes all interfaces of MSR-1 only receive routing updates without sending routing updates
