Refer to the exhibit. After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3. Both FastEthernet interfaces on R2 and R3 are up and configured with the correct IP addresses. MD5 password configured on R2 and R3 match with no issues. What is the minimum change the engineer must make to enable R2 and R3 to communicate and fix the problem?

Refer to the exhibit. IS-IS is the routing protocol on the network. After the team noticed excessive CPU usage on all routers, particularly routers R2 and R6, they configured route summarization on all routers. However, a network engineer noticed that summary routes and more specific routes are present in the routing table on R1.
Which action must the team take so that R1 receives only the summary routes?
