Question 6
Click the Exhibit button.
R5 must advertise Subnet A into IS-IS so that Subnet A and Subnet B can communicate. Subnet B must be able to forward traffic to Subnet A and towards Area 49.0001. However, R5 should not be able to route traffic from Subnet A to Area 49.0001.
Referring to the exhibit, how would you solve this problem?
- Configure Level 2 on all links in Area 49.0002.
- Configure the set protocols isis ignore-attached-bit parameter on R5.
- Configure the set protocols isis overload parameter on R6.
- Configure an export policy on R6 to reject all routes except Subnet B towards R5.
Correct answer: B

- flow
- labeled-unicast
- unicast
- inet-vpn
Correct answer: D
