300-410 Layer 3 Technologies Practice Question
A network engineer is configuring a route map for BGP policy. The engineer wants to match routes that originate from AS 65001 and have a community value of 100:200. The route map should then set the local preference to 200. Which configuration snippet accomplishes this?
⚠ Common exam trap
The trap here is forgetting to define the community list or the AS-path access list, or using a regex that matches AS 65001 anywhere in the path rather than as the origin.

Correct answer & explanation
✓
ip as-path access-list 1 permit ^65001$ ip community-list standard 1 permit 100:200 route-map POLICY permit 10 match as-path 1 match community 1 set local-preference 200
To match routes from AS 65001 with community 100:200 and set local preference, the configuration must include both an AS-path access list and a community list, and apply both matches in the route map. The correct snippet defines the AS-path access list with the regex ^65001$ to match routes originated in AS 65001, defines a standard community list to match 100:200, and then uses both in the route map with the set clause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ip as-path access-list 1 permit ^65001$ route-map POLICY permit 10 match as-path 1 set local-preference 200
Why it's wrong here
This configuration matches routes originating from AS 65001 using an AS-path access list and sets the local preference, but it does not match the community value 100:200. The requirement explicitly states that routes must have the community 100:200. Without a community match, routes from AS 65001 without that community would also be affected, which is not desired.
- ✗
route-map POLICY permit 10 match as-path 1 match community 1 set local-preference 200
Why it's wrong here
This configuration uses an AS-path access list and a community list, but it does not specify how those lists are defined. Without defining the AS-path access list 1 to match AS 65001 and the community list 1 to match 100:200, the route map will not work as intended. The question asks for a configuration snippet that accomplishes the goal, and this snippet is incomplete because it lacks the definitions of the AS-path and community lists.
- ✓
ip as-path access-list 1 permit ^65001$ ip community-list standard 1 permit 100:200 route-map POLICY permit 10 match as-path 1 match community 1 set local-preference 200
Why this is correct
This configuration defines an AS-path access list to match routes originating from AS 65001 (using the regular expression ^65001$) and a community list to match the community 100:200. The route map then matches both conditions and sets the local preference to 200. This fully satisfies the requirement.
- ✗
ip community-list standard 1 permit 100:200 route-map POLICY permit 10 match community 1 set local-preference 200
Why it's wrong here
This configuration correctly defines a community list to match 100:200 and applies it in the route map, but it does not match routes originating from AS 65001. The requirement is to match both the AS origin and the community. Without an AS-path match, routes from any AS with the community 100:200 would match, which is not the intended policy.
