What feature in Junos can be used to prevent certain network addresses from being included in the routing table?

The feature that can be used to prevent certain network addresses from being included in the routing table is martian addresses. Martian addresses refer to specifically defined IP address ranges that are considered invalid and should not appear in the routing table. These addresses include those that are reserved, such as private IP addresses (like those in the ranges 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), as well as public addresses that are not routable. The Junos OS can be configured to filter out these martian addresses to maintain the integrity of the routing table and prevent network issues.

Prefix lists, on the other hand, are typically used to define a set of prefixes for filtering purposes but don't specifically prevent addresses from being included in the routing table; they are used more in route redistribution and summarization contexts. Route maps are more commonly associated with policy-based routing rather than simply preventing routes from entering the routing table. Static routes are specific routes that a network administrator configures manually and do not inherently prevent other addresses from being added to the routing table.
