  7. Dear friends just want to shear with you this nice topic about different types LSA filtering in OSPF enjoy reading [Hidden Content]
  8. I am seeing proper OSPF neighborship among all the six routers. But router 5 Loop 0 is not reachable from R7 and R2. I looked at possibilities like 'ip ospf network ptop' , hello interval etc. OSPF neighboring is happening perfectly with neighbor router. After hour the issue with pinging R4. Does any one faced similar issue? Is there any workaround? Damcel

  10. Ok Gents...... Section 2 - Layer 3 technologies 2.1 – Implement IPv4 OSPF OSPF updates should be advertised only out of the interfaces that are indicated in the topology diagram. Use your rack number as the OSPF process id. Do not manipulate or change the router id. Do not create additional OSPF areas. Configure OSPF Area 2 such that there are no type 5 link-state advertisements (LSAs) in the area. R1 should generate a default route. Configure OSPF over frame relay between R1 and R2 choosing a network type that requires designated router (dr) and backup designated router (bdr) negotiations and the fastest recover times. Ok, so 2 - 4 is obvious, don't make changes. Now 1 is tricky. Need some feedback on this. I configure OSPF under the repsected interfaces, not under the routing process. If anyone disagree, please explain why. Because configuring under the interface ONLY provides advertisements out those interfaces, no others, therefore making all other ports passive. I have a feeling I lost points on this. 5: R1: router ospf 101 area 2 nssa default-information originate R2: area 2 nssa for 6: R1/R2: int s0/0.12 ip ospf network broadcast **But I failed to read the last part requesting the fastest recover times.** I would have done: R1/R2: int s0/0.12 ip ospf dead-interval min hello-multiplier 20 Just goes to show you: 'You must pay attention' DL
  11. Hello Colleagues, All of us who tried to pass the 4.1/4.2 labs had the section related to redistribution from the EIGRP to OSPF. The tasks looks like (very close to the real tasks): Configure EIGRP 100 - Configure EIGRP 100 on SW2. Disable auto-summary. - Redistribute EIGRP 100 into OSPF. The EIGRP routes should be not present in OSPF Area 51 but present in Area 142. - SW2 should generate to the Area 51 an INTRA/INTER area default route. (I had INTRA AREA in my task) I marked the INTRA/INTER area in capital letters purposly - if the task requests that it should be INTER AREA default route the result can be achieved by implementing config like router ospf 11 router-id 11.11.8.8 log-adjacency-changes AREA 51 NSSA NO-REDISTRIBUTION NO-SUMMARY redistribute connected subnets route-map CONN_BB2_2_OSPF redistribute eigrp 100 metric 222 subnets tag 100 network 11.11.8.8 0.0.0.0 area 0 network 11.11.58.8 0.0.0.0 area 51 network 11.11.123.8 0.0.0.0 area 0 In this case we can see default-route as OSPF INTER AREA on R3 or R5 Rack11R3(config)#do sh ip route 0.0.0.0 Routing entry for 0.0.0.0/0, supernet Known via "ospf 11", distance 110, metric 75, candidate default path, type INTER AREA Last update from 11.11.35.5 on Serial1/0, 00:06:27 ago Routing Descriptor Blocks: * 11.11.35.5, from 11.11.8.8, 00:06:27 ago, via Serial1/0 Route metric is 75, traffic share count is 1 But, how it is possible to get this default as INTRA AREA route ? All available sources told me that this task has now solution. If anybody of you has the different oppininion and solution could you be so kind to share it. Thank you ! Best Regards, Ricko.
  12. Dear all, I don't know how to pass default route from OSPF to EIGRP - ip default-network 150.150.0.0 does not work (even if I enter ip route 150.150.0.0 255.255.0.0 null 0). Topology: [router] ISP passes default route to R1 via BGP (OK). R1 passes default route to R2 via OSPF (OK). I need to pass default route from R2 to R3 via EIGRP Internet -- [iSP] -- (BGP) -- [R1] -- (OSPF) -- [R2] -- (EIGRP) -- [R3] Can someone advise, please? Thank you!

  13. Guys, I have seen most of the guys are using "redistributed connected" for the BB1 and BB2 link into OSPF but the question suggested "Note: SW1, SW2, R1, R5 Loopback0 in Area 0. R2 , R3 Loopback 0 in Area 1, R4 Loopback in area2. Backbone 1 and 2 facing interface of R1 and R2 should also be advertised in OSPF. BB1 interface in Area 0 and BB2 interface in ARe1 (Not Redistribute connected) Does any one have an idea how to do this? I have tried this on R3 and R4 but failing to get the route as E2: router ospf 1 distribute-list route-map BB_LINKS in ! ip prefix-list 150_NET seq 5 permit 150.1.5.0/24 ip prefix-list 150_NET seq 10 permit 150.2.5.0/24 ! ! ! ! route-map BB_LINKS permit 10 match ip address prefix-list 150_NET set metric-type type-2 ! route-map BB_LINKS permit 20
  14. 1) question is ping 192.168.20.1 from R20 with source is 200.20.20.20 200.20.20.20 is redistributed to area 0 and area 1 is nssa . am not able to see any routes to 200.20.20.20 in nssa also am not able see to see any default route in nssa
  15. On ABC site 2, we have R11 and R3 via eBGP and R12 and R5 via OSPF. Between R11 and R12 we also have OSPF. Everything works well for all Intra-AS and Inter-AS VPN questions. Problem occurs in question CsC-1. In my setup, the preferred path on ABC site 2 is via the link between R11 and R3. CsS-1 requires vpnv4 between R12 and R13. The vpvn4 session will be closed after a while and the Ping's between VPN XYZ sites are not successful at all. I checked the forwarding plane and have detected that R12's routing table prefers the path over R11 and than from R11 to R3. As soon as I do a shutdown on R12 interface towards R11, vpnv4 session toward R13 comes up and the Pings between the XYZ sites works. I'm looking for a solution to manipulate R12's routing decision. As long as the path between R12 and R5 is used, everything works. One alternative would be to consider CsC-CE redundancy --> vpnv4 + ldp between R12 and R11. This works because I tested this already. Another alternative would be to change the AD of eBGP on R11 but it seem AD change is not a good choice. Question: Do you have also the preferred path issue on R12 (preferred via R11 and not directly via R5?) and how have you solved the issue.
  16. is it preferable to summarize the EIGRP and OSPF network statements in one step router eigrp 34567 network 123.0.0.0 and router ospf 12345 mpls ldp autoconfig area 0 network 123.0.0.0 0.255.255.255 area 0 OR do you think cisco wants the individual specific network statements to match the host route on the interface

  18. Was solving the TSv5 2014 IPv6 phone ticket when encountered problem that R23 was not learning the IPv6 loopback of the R28 R23 was having network type nonbroadcast and R24 network type point to multipoint. Point to multipoint and nonbroadcast are not compatible network type and should not establish adjacency but it did formed it but didn't learn the loopback despite in full state. When I changed the network type to point-to-multipoint (fault removed) on R23 facing to R24 it learned the loopback. The question is why the neighbor relationship came up in the first place if there was mismatch in the OSPFv3 incompatible network types? Could this be Bug?
  19. All, I am trying to practice those K labs. However, I have two questions which I do not know if I am doing right. 1. K6 - RSPAN The question says the remote span destionation is SW4 f0/15, but according to previous task, all unused ports are closed. Here should we open this port? If yes, which vlan should it be in? If no, how is it possible to receive remote-span traffic. 2. K9 - OSPF Area 0 is split. After I looked at the answers provided here, people tend to keep them separated. Why we do not configure a sham-link between R5 and SW3? Thanks in advance for your time.
  20. Dear All, I am confused in the way the routing loops being prevented in MPLS environment. It says that setting DN bit in OSPF header prevents routing loops. Can anyone explain more about this ?

    Hi, in question 3 of UD's IOU; redistribution in OSPF of RIP doesn't work, I 've redistribute connected in order to inject the 192.168.20.1/32 route; every solution i've seen till the time, doesn't show up this, will in real exam 192.168.20.1 route available, & won't be required to "redistribute connected command??? please advise
  22. Hi all, First thanks to all who really helping here, I just started preparation for the CCIE lab and would like to require your suggestions for preparation, I am reading all K8 labs and trying to configure that. At one point i am confused about the TS (Troubleshoot), the CCIE solder wrote a manual on K8, does it contans the troubleshooting about the tickets as well or TS manuals are separate to prepare. TS5 like i never saw any doc for that only people just come on forum and write about the troubleshoot. Looking for your kind reply. Thanks. Scorpio

  24. Currently i am working on K6, and when i configured the ospf, i m getting neighbor down messages in random order on random devices...I have configured my switches to be all connected, so i am getting the conventional "%AMDP2_FE-6-EXCESSCOLL: Ethernet4/2 TDR=0, TRC=0" message. Does it have any thing to do with OSPF neighborship, lets say from SW1 to R1 ? I tried to check if STP is doing anything, but could not find anything relavant. Please hep me go through it quickly. Thanks. M
