Exhibit:
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 and192.168.4.0/24 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
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255
!
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

Suggested Answer: C
Explanation:
We need to use Policy Based Routing (PBR) here on Bangkok router to match the traffic from 192.168.3.0/24 & 192.168.4.0/24 and “set ip next-hop” to HongKong router (172.18.1.2 in this case).
Note: Please notice that we have to apply the PBR on incoming interface e0/3 to receive traffic from 192.168.3.0/24 and 192.168.4.0/24.
