Refer to the exhibit. Which action adds the 10.1.7.6/32 route into the BGP table?

  • A Add a static route for the 10.1.7.6/32 network.
  • B Add summary-address 10.1.7.6 255.255.255.0.
  • C Add the network 10.1.7.6 mask 255.255.255.255 backdoor command.
  • D Add the network 10.1.7.6 mask 255.255.255.255 command.
Explanation

A BGP network statement originates a prefix when that exact prefix and mask are present in the IP routing table. The connected Loopback6 route can therefore be advertised as 10.1.7.6/32 with an exact-mask BGP network statement. summary-address is used to aggregate routes, and backdoor changes route preference behavior rather than originating the prefix.
