In the IS-IS network as shown in the figure, when the routing is stable, change the RTB and RTD to 192.168.224.0/24, then IS-IS topology ______, IP routing information ______.

In the topology shown in the figure, by executing the import-route direct command on RTA, inject 192.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24, 192.168.3.0/24 and 192.168.4.0/ 24 These five routes, and perform the following configuration on RTA, RTB and RTC respectively:
RTA]ospf 1
RTA-ospf-1]area 1
RTA-ospf-1-area-0.0.0.1]network 10.0.0.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 1.1.1.1 0.0.0.0

Then the impossible routes in the RTC routing table are _____

The PBR configuration of a router is known as follows:
polic-based-route pbr_a permit node 10
if-match acl 3000
if-match packet-length 101 1000
apploutput-interface serial 2/0
Assuming that the strategy has been successfully applied, how will the relevant data flow on the router be forwarded?
