Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops?
A. Use route maps on the ASBRs to allow only internal routes to be redistributed.
B. Use route maps on the ASBRs to allow internal and external routes to be redistributed.
C. Use route maps on the ASBRs to set tags for redistributed routes.
D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.
Answer: D
A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously?
A. An ACL blocks TCP port 179 in one direction.
B. IP addresses used to peer are also being sent via EBGP.
C. The OSPF area used for peering is nonbackbone (not area 0).
D. The routers are peered by using a default route sent by OSPF.
