Refer to the exhibit. A network administrator is configuring a BGP router. Which two statements describe the result of the configuration? (Choose two.)
- The routes that match the prefix list PRE192 are least preferred for outbound traffic.
- Received routes that match the prefix list PRE192 are assigned an i in the BGP table.
- Received routes that match the prefix list PRE192 are assigned a ? in the BGP table.
- The routes that match the prefix list PRE192 are considered least desirable for inbound traffic.
- Received routes that do not match the prefix list PRE192 will not advertise the origin attribute to neighbor peers.
Explanation: The sixth decision point in the best-path algorithm is the well-known mandatory BGP attribute named origin. By default, networks that are advertised on Cisco routers using the network statement are set with the i (for IGP) origin, and redistributed networks are assigned the ? (incomplete) origin attribute. The origin preference order is as follows:
- IGP origin
- Exterior Gateway Protocol (EGP) origin
- Incomplete origin
The origin attribute of a prefix can be modified by using the command set origin {igp |incomplete} on a route map. Because the origin attribute is a well-known mandatory BGP attribute, it will be included in the advertisement to BGP peers.
