Distribute List

August 27th, 2015 in ROUTE 300-101 Go to comments

Question 1

Question 2

Explanation

A distribute list is used to filter routing updates either coming to or leaving from our router. In this case, the “out” keyword specifies we want to filter traffic leaving from our router. Access-list 2 indicates only routing update for network 1.2.3.0/24 is allowed (notice that every access-list always has an implicit “deny all” at the end).

    I do not follow the answer for question 1. Can someone help me understand why E is the answer?

    Which one statement is true?

    A. Traffic from the 172.16.0.0/16 network will be blocked by the ACL.
    B. The 10.0.0.0/8 network will not be advertised by Router B because the network statement for the 10.0.0.0/8 network is missing from Router B.
    C. The 10.0.0.0/8 network will not be in the routing table on Router B.
    D. Users on the 10.0.0.0/8 network can successfully ping users on the 192.168.5.0/24 network, but users on the 192.168.5.0/24 cannot successfully ping users on the 10.0.0.0/8 network.
    E. Router B will not advertise the 10.0.0.0/8 network because it is blocked by the ACL.

    Possible answers to my knowledge:
    B. The 10.0.0.0/8 network will not be advertised by Router B because the network statement for the 10.0.0.0/8 network is missing from Router B.
    C. The 10.0.0.0/8 network will not be in the routing table on Router B.
    E. Router B will not advertise the 10.0.0.0/8 network because it is blocked by the ACL.

    jolly,

    the ACL that is used for distribution has an implicit deny all, it only allows updates for the 172.16.0.0/16 network

    Ahh, I finally figured it out. I think.

    Distribution-List is to limit information in routing tables. Where Access-Groups are to limit individual device information.

    On Router R1, process EIGRP 1 is redistributing routes from process OSPF 2, calling route map
    fred with the redistribute ospf 2 route-map fred command. R1 has learned intra-area routes for
    10.1.1.0/24 and 10.1.2.0/24 in part because of the Type 2 LSAs known for each subnet. The route
    map filters route 10.1.1.0/24 and allows 10.1.2.0/24 through. Which of the following commands
    on Router R1 list subnet 10.1.1.0/24? (Choose two.)
    a. show ip route
    b. show ip eigrp topology
    c. show ip ospf database
    d. show ip eigrp topology 10.1.1.0/24

    A and C. The problem states that R1 has learned OSPF intra-area routes for 10.1.1.0/24,
    so show ip route will display that subnet. As an intra-area route based on a Type 2 LSA,
    the show ip ospf database command lists the summary of the LSAs, including the
    10.1.1.0 subnet number for that Type 2 LSA. However, because the redistribution
    filtering discards subnet 10.1.1.0/24, this value will not be included in the EIGRP
    topology table.

    Can someone clarify the following question for me? I could see where B, C or E could be correct. Is it because you could potentially have another routing protocol advertising that network? Or maybe I’m just overthinking the question???

    Which one statement is true?

    A. Traffic from the 172.16.0.0/16 network will be blocked by the ACL.
    B. The 10.0.0.0/8 network will not be advertised by Router B because the network statement for the 10.0.0.0/8 network is missing from Router B.
    C. The 10.0.0.0/8 network will not be in the routing table on Router B.
    D. Users on the 10.0.0.0/8 network can successfully ping users on the 192.168.5.0/24 network, but users on the 192.168.5.0/24 cannot successfully ping users on the 10.0.0.0/8 network.
    E. Router B will not advertise the 10.0.0.0/8 network because it is blocked by the ACL.

    why i cant see some of the questions? in some pages I can only see “Question 1, 2 or whatever” but under that there is no question. i can only see the red writing saying the question number..

  27. BK
    December 16th, 2015

    Anyone can help explain Question 1?

    As per my lab router:

    Router A
    A#show run | sec router
    router eigrp 1
    network 0.0.0.0
    auto-summary
    A#

    Router B
    B#show run | sec router
    router eigrp 1
    network 172.16.0.0
    network 192.168.5.0
    distribute-list 7 out FastEthernet0/0
    auto-summary
    B#

    A#show ip route eigrp
    (nothing)
    A#

    B#show access-lis
    Standard IP access list 7
    10 permit 172.16.0.0, wildcard bits 0.0.255.255 (3 matches)

    B#show ip route eigrp
    D 10.0.0.0/8 [90/409600] via 172.16.0.1, 00:04:27, FastEthernet0/0
    B#

    Answer Discussion:

    A is wrong, as there is a permit 172.16.0.0/16 out, thus the route will be advertised out from B to A.

    B is wrong, as there is no directly connected 10.0.0.0/8 network to begin with.

    C is wrong, as unless this is deny configured in the Router A’s EIGRP 1 to deny 10.0.0.0 (assumption), the route will be advertised by A to B.

    D is misleading, users on Router A’s 10.0.0.0/8 network don’t even have a router to Router B’s 192.168.5.0/24, but users on Router B does have the route to Router A’s 10.0.0.0/8, unless router A already has perhaps static route to 192.168.5.0/24 next hop Router B.

    E should be wrong, the ACL is to permit the advertising of 172.16.0.0/16 route from B to A, nothing to do with 10.0.0.0/8.

    @BK
    for me E should be right because there’s no permit any in the access-list so it will block anything aside from the permitted IP.
    This is just a tricky question.

  33. cls
    August 13th, 2016

    Here is the reason for Q1

    A. Traffic is not blocked by ACL. It is permitted outbound. There is no inbound ACL so it is permitted.

    B. Network statement 10.0.0.0 is not needed on Router B since it is not a directly connected subnet

    C. It will be in the routing table but not advertised out s0

    D. Ping will not work either way. Remember that for ping to work, there must be both transmit and receive. This is very fundamental.

    Dude, I failed today with a 640. The ‘300-101: Implementing Cisco IP Routing’ exam is completely different then what is on this site. Not even close. There are maybe 10 questions that are the same… What happened???

    Finally passed the Route! Was a long journey… As I got caught in the update. However came across the ebay dump mentioned by others and passed the exam yesterday. The materials are still vailid. Like how he has packet tracer available for 3 of the simulations. It was good practice. No new questions.

    The link below is the ebay matierlas I have utilized, if you would like to use as well:
