Network administrators use the route map tool for many purposes. Which three options are more common applications for route maps? (Choose three.)
- autonomous system synchronization
- network monitoring
- network topology mapping
- route filtering with redistribution
- policy-based routing
- BGP
Explanation: Network administrators use route maps for several sophisticated network tasks. The three most common applications are:
- Route filtering during redistribution: Redistribution between different routing protocols almost always requires some filtering. Route maps are preferred for this because, unlike basic distribute lists, they allow administrators to also manipulate routing metrics using set commands during the redistribution process.
- Policy-based routing (PBR): Route maps are used to identify specific traffic based on source/destination addresses, protocol types, or applications. Once matched, a set command dictates a specific interface or next-hop address for that traffic, allowing administrators to define a routing policy that differs from standard destination-based routing.
- BGP (Border Gateway Protocol): Route maps are the primary tools for implementing BGP policies. They are assigned to specific BGP neighbor sessions to control which routes enter or leave the BGP process and to perform sophisticated manipulation of BGP path attributes.
The other options provided—autonomous system synchronization, network monitoring, and network topology mapping—are not listed as common applications for route maps in the source material.
