Which two configuration commands will complete the configuration on Certkiller 1 so that when Certkiller 1 send the BGP updates to Certkiller 4, three copies of the customer’s AS number (65103) willb e prepended to the AS-Paht? (Choose two)
A.
Set as-path prepend 3
B.
Set as-path tag 65103 65103 65103
C.
Neighbor 10.1.1.4 route-map test in
D.
Neighbor 10.1.1.4 route-map test out
E.
Set as-path prepend 65103 65103 65103
Explanation:
Manual AS-path manipulation is configured using a route-map with the set ap-path prepend statement, which prepends the specified AS-numbers to the routes matched with the match condition. The route-map is then applied to the outgoing updates to an EBGP neighbor. The prepending is made first, then the route is subject to the normal AS-path modification procedures when it is sent over an EBGP session. The rotue-map can also be used to select only a subset of routes that should have their AS-path manually manipulated. In the appropriate route-map permit statement, the set as-path prepend command is used.
