Ticket 1 – OSPF Authentication

May 6th, 2018 in TSHOOT v2 Go to comments

1.Client is unable to ping R1’s serial interface from the client.

Problem was disable authentication on R1, check where authentication is not given under router ospf of R1. (use ipv4 Layer 3)

Configuration of R1:

interface Serial0/0/0
 description Link to R2
 ip address 10.1.1.1 255.255.255.252
 ip nat inside
 encapsulation frame-relay
 ip ospf message-digest-key 1 md5 TSHOOT
 ip ospf network point-to-point
!
router ospf 1
 router-id 1.1.1.1
 log-adjacency-changes
 network 10.1.2.0 0.0.0.255 area 12
 network 10.1.10.0 0.0.0.255 area 12
 default-information originate always
!

Configuration of R2:
interface Serial0/0/0.12 point-to-point
 ip address 10.1.1.2 255.255.255.252
 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 TSHOOT
!

Answer: on R1 need command ip ospf authentication message-digest”

Ans1) R1
Ans2) IPv4 OSPF Routing
Ans3) Enable OSPF authentication on the s0/0/0 interface using the “ip ospf authentication message-digest” command.

Note:

There are two ways of configuring OSPF authentication:

interface Serial0/0/0
  ip ospf message-digest-key 1 md5 TSH00T
!
router ospf 1
  area 12 authentication message-digest

OR

interface Serial0/0/0
  ip ospf authentication message-digest
  ip ospf message-digest-key 1 md5 TSH00T

So you have to check carefully in both interface mode and “router ospf 1”. If none of them has authentication then it is a fault.

    is the answer correct for ticket 1? because there is no network command for the serial interface how is it participating in OSFP!

    TIP :

    Client 1 : can ping DSW1, R1 SUB Interface (10.1.1.2) and R2
    cannot ping R1 s0/0/0 (10.1.1.1 ) and web server
    ============================

    DSW1 : can ping Client 1, R1 SUB Interface,
    cannot ping R1 s0/0/0 and web server
    traceroute to web server is NOT Complete
    ==========================

    R1: sh run and check s0/0/0 lack of ” ip ospf auth message-digest ( this is the issue )
    ===============
    R2: sh run and check s0/0/0.12 and compare with R1.

    Hope this help someone

    I failed today as well ! There was several MCQ which I haven’t seen before either! There was also an strange Ticket question! The access port on ASW1 connected to the Client 1 was shut down administratively and I could see the “shut down” command in the ASW1 under the interface configuration but there was no option to point this issue !

    OSPF Authentication is already enabled on R1 s0/0/0 interface…shouldn’t the correct answer be enable ospf authentication on R4?

    All my buddies who used the premium dump passed the test last week. It looks like the premium is still valid. I am not so sure about the free dump.
    I am planning to take the test this week. Wish me luck guys!!

    Hi all,

    I had two questions last week which look new or same issue on different device.

    1- passive interface configured under eigrp router on DSW1 instead of R4
    2- there was no OSPF neighbor relationship between R1 and R2 but the issue was not auth under sub-int on R1

    Could you please kindly assist if anyone has any idea what these issues are regarding to as I booked another exam in two days?

    Your guidance is much appreciated.

    Cheers

    Basically the fastest way to get this is to go straight to R1. Confirm that there are not issues pinging the WEB server, NAT is a likely issue. Then work your way back to the next router and make sure it can ping the webserver. If R2 can’t and there is no entry in the routing table for the webserver then there is an routing issue. Confirm that ospf works between R1 and R2. Route redistrabution is working, default-information originate (default route) etc. Confirm that ospf is working between R1-R2. This is a very easy lab, R4 does not have a route, same with R3 and R2.

    Can be solved by a CCNA level person. Just remove the commands you don’t understand but at ccnp you can copy the missing command from one router interface to the next. Reachabliity first then is NAT working. If there is no route to R2 then pinging wont work and NAT will never happen because traffic will never reach R1. Make sure routing works first.

    This logically is simple, issue is finding the problem very quickly. CCNA 10-13 mins (you will start an client and work your way forward), ccnp about <5 mins (see above why).

    I thought in premium, there will be visual topoly as well, but there is only text written question and simulator for switch & routers, I am confused that in exam there will be no topology shown ?
    only question ??

    sims are 100%. There are bugs in the actual test with show commands on this ticket. Best to stay with the running-config for accurate information.

    The questions from this site and BGP, HSRP simlet, and 12 ticket learn all the tickets you will pass i promise you. I cannot say which one to learn because cisco can test you in any ticket. so i was prepared that’s why i pass so no short cut study your tickets practice them again and again please!!!!

    For IPV4:
    R1: (BGP/ NAT/ NAT ACL/R1 ACL )
    ping 10.1.1.1 – OK , 10.1.1.2 – OK and 10.2.1.1 – OK
    show run

    R1: (OSPF Authentication)
    Ping 10.1.1.1 – NO, 10.1.1.2 – OK and 10.2.1.1 -OK
    show ip ospf neighbor on R1 and R2 – compare R1 and R2
    show run

    R4: (EIGRP or redistribution/ route-map)
    Ping 10.1.1.1 – OK , 10.1.1.2 – NO and 10.2.1.1 – OK
    or Ping 10.1.1.1 – NO and 10.1.1.2 -No and 10.2.1.1 -OK\
    show ip eigrp neighbor – check eigrp neighbor , if No, maybe passive interface or AS
    show run to check
    if they have neighbor, show run to check redistribution – route map ospf -> eigrp
    deny / permit

    ping 10.1.1.1 – NO, 10.1.1.2 – No and 10.2.1.1 – NO
    DSW1 (Vlan filter or DHCP helper)
    show run to check

    or ASW1 (port security / vlan access / switch to switch connection (trunk) )

    show ip int brief – check port (down or up ) if down , port security
    show interface trunk – check trunk , if 20,200 , trunk issue
    if 10,20,200 -> show run – > check f0/1-2 should be vlan access

    for IPV6
    R2: ospf
    show ipv6 ospf neighbor on R2 and R3
    show run

    R3: tunnel
    show ipv6 ospf neighbor on R3
    show run on R3 and R4 – compare

    R4: redistribution ospf -> rip
    show ipv6 route on R3 and R4
