  To allow the use of external, internal, and local administrative distances that could be a better route than other external, internal, or local routes to a node, use the distance bgp command in address family or router configuration mode. To return to the default values, use the no form of this command. distance bgp external-distance internal-distance local-distance no distance bgp

  Syntax Description external-distance Administrative distance for BGP external routes. External routes are routes for which the best path is learned from a neighbor external to the autonomous system. Accept table values are from 1 to 255. The default is 20. Routes with a distance of 255 are not installed in the routing table. internal-distance Administrative distance for BGP internal routes. Internal routes are those routes that are learned from another BGP entity within the same autonomous system. Accept table values are from 1 to 255. The default is 200. Routes with a distance of 255 are not installed in the routing table. local-distance Administrative distance for BGP local routes. Local routes are those networks listed with a network router configuration command, often as back doors, for that router or for networks that are being redistributed from another process. Accept table values are from 1 to 255. The default is 200. Routes with a distance of 255 are not installed in the routing table. Defaults external-distance: 20 internal-distance: 200 local-distance: 200

  In this case, the internal distance is 60 and the external is 90, and the local distance is 120 (same as RIP).

• Question 653:

  How are the Cisco Express Forwarding table and the FIB related to each other?

  A. The FIB is used to populate the Cisco Express Forwarding table.
  B. The Cisco Express Forwarding table allows route lookups to be forwarded to the route processor for processing before they are
  C. There can be only one FIB but multiple Cisco Express Forwarding tables on IOS devices.
  D. Cisco Express Forwarding uses a FIB to make IP destination prefix-based switching decisions.
  D. Cisco Express Forwarding uses a FIB to make IP destination prefix-based switching decisions.

• Question 654:

  Refer to the exhibit.

  

  If a connection failure occurs between R1 and R2, which two actions can you take to allow CR-1 to reach the subnet 192.168.192.0/24 on R2? (Choose two.)

  A. Create a static route on R1 for subnet 192.168.192.0/24 towards R3 and redistribute it into OSPF.
  B. Turn up a BGP session between CR-1 and R1.
  C. Create a static route on R1 for subnet 192.168.192.0/24 towards R3 and redistribute it into BGP.
  D. Turn up an EIGRP session between R1 and R3 with AS 65535.
  E. Create an OSPF virtual link between CR-1 and R2 to bypass R1.
  A. Create a static route on R1 for subnet 192.168.192.0/24 towards R3 and redistribute it into OSPF.
  B. Turn up a BGP session between CR-1 and R1.

• Question 655:

  Refer to the exhibit.

  

  Assuming that the peer is configured correctly and the interface is up, how many neighbors will be seen in the EIGRPv6 neighbor table on this IPv6-only router?

  A. one neighbor, which will use a local router-id of 6010. AB8. . /64
  B. one neighbor, which will use a local router-id of 6020. AB8. . /64
  C. none, because EIGRPv6 only supports authenticated peers
  D. none, because of the mismatch of timers
  E. none, because there is no EIGRP router ID configured
  E. none, because there is no EIGRP router ID configured

  ---

  Configuring EIGRP for IPv6 has some restrictions; they are listed below:

  The interfaces can be directly configured with EIGRP for IPv6, without the use of a global IPv6 address. There is no network statement in EIGRP for IPv6. The router ID needs to be configured for an EIGRPv6 protocol instance before it can

  run.

  EIGRP for IPv6 has a shutdown feature. Ensure that the routing process is in "no shut" mode to start running the protocol.
