In what way do Route-Maps compare to ACLs?

Route-Maps provide additional capabilities through attributes, setting them apart from Access Control Lists (ACLs). While ACLs primarily serve the function of permitting or denying traffic based on defined criteria, Route-Maps extend this functionality by offering more sophisticated manipulations of routing decisions.

Route-Maps allow for the evaluation of various attributes associated with routes, such as metric values, route tags, and next-hop addresses. This capability enables network engineers to perform complex routing policy decisions, such as controlling route redistribution between protocols, filtering routes based on various conditions, and altering route advertisements.

This added layer of complexity means that Route-Maps can handle not just access control, but also route manipulation and policy enforcement in dynamic routing environments. Thus, when comparing Route-Maps to ACLs, the enhanced flexibility and additional capabilities offered by Route-Maps emphasize their utility in more advanced network configurations.
