An engineer applied the configuration on R1 to prevent network 192.168.1.0/24 from being propagated outside of area 5. After the change, users have reported they are not able to access any of the application servers that were working before. While checking the routing table of the peer router. The engineer notices R1 stopped propagating any routes outside are 5. Which action must be taken to fix the problem?

A network operator must inject a Level 1 route from XR2 (10.16.16.0/24) into the ISIS topology. Which configuration allows the injection in a way that XR3 and XR1 have a valid and working route for 10.16.16.0/24?

Refer to the exhibit. A network engineer is investigating a report of packet drops in an application running on a server connected to PE2. The engineer determined that:
- The OSPF adjacency in area 0 is up, and it is learning the loopback
addresses of all routers in area 0.
- Traffic from users connected to PE1 to the application is also
passing normally.
- Packets from PE2 back to PE1 are being dropped.
Which action resolves the issue?
Refer to the exhibit.
While configuring router 2 with all the default values, a network engineer cannot see any route received in router 1. How should the engineer solve the issue?
