• Question 451:

  SIMULATION

  Policy Based Routing Sim

  

  BorderRouter(config)#access-list 101 permit tcp any any eq www

  Company A can has two links which can take it to the Internet. The company policy demands that you use web traffic to be forwarded only to Frame Relay link if available and other traffic can go through any links. No static or default routing is allowed.

  1) Access list that catches the HTTP traffic:

  2) Route map that sets the next hop address to be ISP1 and permits the rest of the traffic:

  BorderRouter(config)#route-map pbr permit 10BorderRouter(config-route-map)#match ip address 101BorderRouter(config-route-map)#set ip next-hop 10.1.101.1BorderRouter(config-route-map)#exit

  3) Apply the route-map on the interface to the server in the EIGRP Network:

  BorderRouter(config-route-map)#exitBorderRouter(config)#int fa0/0BorderRouter(config-if)#ip policy route-map pbrBorderRouter(config-if)#exitBorderRouter(config)#exit

  BorderRouter#show route-map

  Correct Answer. Check the answer below

  All the HTTP traffic from the EIGRP Network should go through Frame Relay link if available and all the other traffic should go through either link. The only router you are able to administrate is the Border Router, from the EIGRP Network you may only send HTTP traffic. As the other people mentioned, actually it is not a BGP lab. You are not able to execute the command “router bgp 65001″

  1) Access list that catches the HTTP traffic:BorderRouter#access-list 101 permit tcp any any eq www

  Note that the server was not directly connected to the Border Router. There were a lot of EIGRP routes on it. In the real exam you do not know the exact IP address of the server in the EIGRP network so we have to use the source as “any” to catch all the source addresses.

  2) Route map that sets the next hop address to be ISP1 and permits the rest of the traffic:BorderRouter(config)#route-map pbr permit 10 BorderRouter(config-route-map)#match ip address 101 BorderRouter(config-route-map)#set ip next-hop 10.1.101.1 BorderRouter(config-route-map)#exit

  “If the packets do not meet any of the defined match criteria (that is, if the packets fall off the end of a route map), then those packets are routed through the normal destination-based routing process. If it is desired not to revert to normal

  forwarding and to drop the packets that do not match the specified criteria, then interface Null 0 should be specified as the last interface in the list by using the set clause.”

  3) Apply the route-map on the interface to the server in the EIGRP Network:BorderRouter(config-route-map)#exit BorderRouter(config)#int fa0/0 BorderRouter(config-if)#ip policy route-map pbr BorderRouter(config-if)#exit BorderRouter(config)#exit

  4) There is a “Host for Testing”, click on this host to open a box in which there is a button named “Generate HTTP traffic”. Click on this button to generate some packets for HTTP traffic. Jump back to the BorderRouter and type the

  command “show route-map”.

  BorderRouter#show route-map

  In the output you will see the line “Policy routing matches: 9 packets…”. It means that the route-map we configured is working properly.

• Question 455:

  A network engineer is configuring a solution to allow failover of HSRP nodes during maintenance windows, as an alternative to powering down the active router and letting the network respond accordingly. Which action will allow for manual switching of HSRP nodes?

  A. Track the up/down state of a loopback interface and shut down this interface during maintenance
  B. Adjust the HSRP priority without the use of preemption.
  C. Disable and enable all active interfaces on the active HSRP node.
  D. Enable HSRPv2 under global configuration, which allows for maintenance mode.
  A. Track the up/down state of a loopback interface and shut down this interface during maintenance

  B. The trailing zeroes in any 16-bit segment do not have to be written.
  C. The leading zeroes in any 16-bit segment do not have to be written.
  D. Any single, continuous string of one or more 16-bit segments that consists of all zeroes can be represented with a double colon.
  E. The maximum number of times a double colon can replace a 16-bit segment that consists of all zeroes is two.
  F. Two zeroes in the middle of any 16-bit segment do not have to be written.
