QUESTION
Bangkok is using ECMP to reach to the 192.168.5.0/24 network. The administrator must configure Bangkok in such a way that Telnet traffic from 192.168.3.0/24 and 192.168.4.0/24 networks uses the HongKong router as the preferred router.
Which set of configurations accomplishes this task?
A . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
route-map PBR1 permit 10
match ip address 101
set ip next-hop 172.18.1.2
interface Ethernet0/3
ip policy route-map PBR1
B . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
route-map PBR1 permit 10
match ip address 101
set ip next-hop 172.18.1.2
interface Ethernet0/1
ip policy route-map PBR1
C . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
!
route-map PBR1 permit 10
