Both IS-IS and OSPF run on a network as shown in the following figure. Route import is configured on RTB and RTC respectively. All the routers are connected through GE interfaces. Routes to the network segment 2.2.2.2/32 is imported to the OSPF process using the import-route direct command on RTD. The default settings are retained for all the other configurations. Which of the following statements regarding this network is false?

The following configuration can be performed on RTC to filter out only routes to the network segment 2.2.2.2/32 when RTC imports routes:

[RTC] ip ip-prefix 10 index 1 deny 2.0.0.0 8 less-equal 32

[RTC-isis-1]filter-policy ip-prefix 10 import ✘ On RTB, adjust the IS-IS preference to 160 to avoid generation of sub-optimal routes on the network ✘ The following configuration can be performed on RTC to filter out routes from RTD to the network segment 2.2.2.2/32 when RTC imports OSPF routes:[RTC-acl-basic-2001]rule 5 deny source 2.0.0.0 0.255.255.255

[RTC-acl-basic-2001]rule 10 permit

[RTC-isis-1]filter-policy 2001 import ✘ RTB learns that RTA is the next hop of the route to the network segment 2.2.2.2/32 ✔

The IP routing entries whose destination network segment is 10.0.2.2/32 on R1 can be generated through OSPF only when the IS-IS preference of R2 is

changed to 5 ✘ If the IS-IS preference of R1 is changed of R1 is changed to 5, the IP routing entries whose destination network segment is 10.0.2.2/32 on R1 are generatedthrough OSPF ✘ If the IS-IS preference of R1 is changed to 5, the IP routing entries whose destination network segment is 10.0.2.2/32 on R1 are generated through IS-IS ✘ If the IS-IS preference of R2 is changed to 5, the IP routing entries whose destination network segment is 10.0.2.2/32 on R1 are generated through IS-IS ✔
