Policy Based Routing Sim

February 8th, 2015 in Lab Sim, LabSim Go to comments


Company TUT has two links to the Internet. The company policy requires that web traffic must be forwarded only to Frame Relay link if available and other traffic can go through any links. No static or default routing is allowed.



Answer and Explanation:

Notice: The answer and explanation below are from PeterPan and Helper.Please say thank to them!

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(config)#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

(Update: We don’t need the last command route-map pbr permit 20 to permit other traffic according to Cisco:

“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.”

Reference: http://www.cisco.com/en/US/products/ps6599/products_white_paper09186a00800a4409.shtml)

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

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.

Note: We have posted a Policy Based Routing lab on GNS3 similar to this sim with detailed explanation, you can read it here.

    guys help me

    In which scenario can asymmetric routing occur.
    1. active/active firewall setup
    2. reduntant routers running VRRp
    3. active/standby firewall setup
    4. simple path in and out of the network

  5. jZ
    April 15th, 2017

    the answer is 1. active/active firewall setup

    Hi JZ,

    what about the question on how to mitigate asymmetric routing using active/active firewall setup?

    Is it thru using a layer 3 device or router? Forgot the other options.

    BorderRouter(config)#route-map pbr permit 10
    BorderRouter(config-route-map)#match ip address 101
    BorderRouter(config-route-map)#set ip next-hop
    I think this is wrong “match ip address 101”
    It have to be “match policy-list 101”
    IsnĀ“t it?

  12. PBR route-maps
    May 22nd, 2017

    Can somebody please reply as if 2nd statement is needed or not to allow all other traffic==>#route-map PBR permit 20.

    Cisco press documentation said “There is always an implicit deny statement at the end of a route map” http://www.ciscopress.com/articles/article.asp?p=2273507&seqNum=12 .

    But also they mention that “The policy routing process proceeds through the route map until a match is found. If no match is found in the route map, or the route map entry is made a deny instead of a permit, then normal destination-based routing of the traffic ensues”. on http://www.cisco.com/en/US/products/ps6599 products_white_paper09186a00800a4409.shtml

    Please advise if following is correct or not:
    #route-map PBR permit 10
    ()#match ip address 101
    ()#set ip address

    #route-map PBR permit 20
    thank you

    @ Chaka: “match ip address” is the way to go, since you are trying to match with an ACL, that is the right statement when filtering for either ACLs or prefix list.

    your ACL >>> is not right access-list 111 permit icmp any any echo

    should be access-list 111 permit tcp any any eq 80

    when test use the following in gns3

    telnet 80

    this will show when you do sho route map for confermation

    Hi Bro
    the access-list 111 is the number of ACL that was in the test cause in this solution the number is 101 ?

    who took exam last days? what labs are in exam now?

  30. mills
    July 20th, 2017

    passed yesterday.

    used the official ccnp route 300-101 guide book, jeremy videos from cbtnuggets and finally digitaltut.com.

    the dumps on digitaltut are 85% valid, quite impressive i must say. didnt use any other dumps to prepare (i can be lazy sometimes)

    sims were eigrp ospf redistribution, eigrp evaluation, ospf evaluation and policy based routing sim.

    all sims were the same with little modifications on IP addresses and interface numbers. but i must mention something about the policy based routing sim. it was kinda different. similar topology as we have on digitatut however the task was to allow all http traffic only to go through one ISP (framerelay link) while any other traffic can go either way. so this is what i did.

    access-list 100 permit tcp any any eq 80

    route-map ROUTE-MAP deny 10
    match ip address 100
    set ip next-hop THE-OTHER-ISP

    route-map ROUTE-MAP permit 20

    So i felt since they wanted only http traffic to go to framerelay while any other traffic can go eitherway, in other words they do not want http traffic to go through the other isp so i figure i should deny http traffic from going through the other isp while it will be business as usual for other traffic.

    well that was what i could come up with with al the exam tension and the racing time.

    at the end of the day i passed with 812. i am sure of about 80 to 85% of the other none sim questions because off course they were here on digitatut.

    please share your thoughts on the pbr sim senario and what the best approach would have been. because i feel i got it wrong, that should explain my score of 812. you can share your thoughts with me mbomat at yahoo dot come. good luck everyone, see you on the switch page…………
