An Autonomous System (AS) is a set of routers under the control of one technical administration that presents a common routing policy.

Which of the following IP addresses can be used on a public network? (Select 2 answers)

The ospf dr-priority value ranges from 0 to 255 and is 64 by default.

Based on BGP route selection rules, how are Origin attributes listed in descending order of priority?

Policy-based routing and routing policies implements the forwarding of data packets in different ways: A routing policy mainly controls packet forwarding. According to the routing policy, packets can be forwarded without a routing table; Policy-based routing mainly controls the importing, advertising, and receiving of routing information.

Which methods can be used to import local routes into BGP? (Select 2 answers)

A failure in establishing a BGP connection can be addressed by checking the TCP connectivity and BGP peer configurations.

Route importing can be used when multiple routing protocols run on different networks and these networks need to share routing information.
