NO.133 The Serial0/0 interface of the router MSR1 of the Shenzhen branch of XYZ Company is directly connected to the Serial0/0 interface of the ISP router MSR2 through the WAN line, and the Serial0/0 interface address of the MSR2 is 100.126.12.1. XYZ company can visit the website of Beijing head office at 202.102.100.2 through this ISP. There is no routing protocol running on MSR1, only the following static route is configured: ip route-static 202.102.100.2 24 100.126.12.1
So which descriptions about this route and MSR1 routing table are correct? (multiple choice)

If the address of the network segment where 100.126.12.1 is located is unreachable, then the route will not be written into the routing table

As long as the physical state of the outbound interface corresponding to the route is up, the route will be written into the routing table

If the outbound interface corresponding to the route is broken, the route will be deleted from the routing table

This is a static route with a priority of 60 and a cost of 0
