AS 111 wanted to use AS 200 as the preferred path for 172.20.5.0/24 and AS 100 as the backup. After the configuration, AS 100 is not used for any other routes.





Which configuration resolves the issue?


  1. route-map SETLP permit 10
    matchip address prefix-list PLIST1
    set local-preference 99
    route-map SETLP permit 20

  2. routerbgp 111
    no neighbor 192. 168.10.1 route-map SETLP in
    neighbor 192.168.20.2 route-map SETLP in

  3. route-map SETLP permit 10
    matchip address prefix-list PLIST1
    set local-preference 110
    route-map SETLP permit 20

  4. routerbgp 111
    no neighbor 192. 168.10.1 route-map SETLP in
    neighbor 192.168.10.1 route-map SETLP out

Answer(s): A

Explanation:

There is an implicit deny all at the end of any route-map so all other traffic that does not match 172.20.5.0/24 would be dropped. Therefore, we have to add a permit sequence at the end of the route-map to allow other traffic.
The default value of Local Preference is 100 and higher value is preferred so we have to set the local preference of AS100 lower than that of AS200.



Refer to the exhibit. The ISP router is fully configured for customer A and customer B using the VRF-Lite feature.

An engineer is implementing a coordinated change with a server team. As part of the change, the engineer must configure interface GigabitEthernet2 in an existing VRF "RED" then move the interface to an existing VRF "BLUE" when the server team is ready. The engineer configured interface GigabitEthernet2 in VRF "RED":

interface GigabitEthernet2
description Migration ID: B410A82D0935G35
vrf forwarding RED
ip address 10.0.0.0 255.255.255.254
negotiation auto

Which configuration completes the change?


  1. interface GigabitEthernet2
    novrf forwarding RED
    vrf forwarding BLUE
    ip address 10.0.0.0 255.255.255.254

  2. interface GigabitEthernet2
    noip address
    vrf forwarding BLUE

  3. interface GigabitEthernet2
    novrf forwarding RED
    vrf forwarding BLUE

  4. interface GigabitEthernet2
    noip address
    ip address 10.0.0.0 255.255.255.254
    vrf forwarding BLUE

Answer(s): A
