OSPF Default Routing [7:46111]
Hey all, I am currently using the CCIE Practical sutides text and I am confused on the OSPF Default routing part. On Page 795, Karl says that is you use the DEFAULT-NETWORK x.x.x.x command generate the Deafult route you need the ALWAYS statment present in the DEFAULT-INFORMATION ORIGINATE command. Then in Lab 24, as an optional step he wants you to generate the default route and proporgate it throughout the OSPF network without using static routes and if the network becomes unavailable he does not want the default route to proporgate. Now, in his Lab walkthorough he says to put the ALWAYS statment in the DEFAULT-INFORMATION ORIGINATE command but if you do that then the deafault route will proporgate even if the network is down. My question is Why would I ever want the ALWAYS statment and is he wrong about the requierments listed abaove?

RE: Disable show run [7:46112]
There are level of commands 1-7 I think not sure though. What you can do is setup username auth. and assigh users with levels of commands. But I dont think you can just turn sho runn off. Hope that helps.

Re: OSPF Default Routing [7:46111]
Thank you for your reply :) If I keep the ALWAYS statment in there the route still propagates even when I turn/unplug the ethernet on dental_ho. If I take out the ALWAYS statment the optional requirement is met. That is if I uplug the the interface the route stops propagating. What I think is going on here is that the ALWAYS tells the router to propagate even if the route map condition is not met. I think this is a mistake in the book. But what really bugs me is that Karl said you must have the ALWAYS in there if your going to use IP OSPF DEFAULT-NETWORK command but I took out the always and everything worked fine.

RE: EIGRP routing issue. [7:42479]
Im am not sure why this is happening but I'ill take a stab at it. If a router that is running EIGRP borders 2 major network (i.e. 209.53.131.0 Router-208.181.160.0) and auto-summary is turned on within the EIGRP config, it will advertise the 208.181.160.0/24 to the network. It will also add the 208.181.160.0/24 to the route table and point it to Null 0. (Im not sure why it does this but I bet its to prevent a routing loop) You can try to turn the auto-summ off on that router. Again I am not sure whats going on here but that is my guess. Hope this helps :) Karim Gueye Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=42520t=42479 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Added HSRP can't surf or Resolve DNS [7:42592]
I cannot think of a scenario where you would use HSRP without the standby and active interface not plugged into a switch/hub or 2 seperate switches that are trunked. Here is an ASCII visual that may help: 65096509 \ / \ / -HUB/SWITCH--- | | HOST OR 6509 6509 \/ \ / switch switch || || --host--- The configs you posted look fine Make sure you Physical design matches one of the ASCII visuals.

RE: OSPF over ISDN demand circuit [7:42348]
I have seen this b4 when I configured Demand circut. First of all, OSPF will attempt send an update accross that ISDN line when somthing changs in the ospf database. So my guess is somthin is changing in the database (i.e. a route flap) Now, when I had this problem the router that was running OSPF /w demand circut and intiating the ISDN call was Mutally redistributing between 2 protocols (ospf and igrp)and because I was using a classess RP, IGRP, and running the same major NET on the eth and ISDN, IGRP was adv. the ISDN network. I was also running PPP over the ISDN link. Here was my problem: OSPF dials the adjacent router to update. When a PPP session is estab. a host route gets installed on both PPP talkers (it's just the way PPP works do ask me why) When OSPF is done the BRI will go down. Here is the fun part :) That host route dissapears so that route is pulled from the ospf database adn from IGRP, but IGRP redistrbutes back to OSPF that the host route is gone and the MAXAGE of the OSPF DB changes and that is why OSPF dials again. The way that cisco recommends fixing this is to filter that host route from being redistributed into OSPF. That should fix the problem. I hope this helps :) Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=42377t=42348 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Question on RIPv2 example in Doyles routing book [7:41991]
When a router that is running RIPv1 recieves a RIPv2 update with a subnet (i.e 192.168.13.80\28) will the RIPv1 router add the subnet and mask to the routing table as is or will it still apply the mask of the recieving interface ont the the subnet? According to doyles book (Chapter 7 troubleshooting exercises) the RIPv1 route will add the mask of the recieving interface.

Summary addressing [7:41998]
I promise I will not be a knowledge leech, I will contribute what I know as well. Ofcourse I do have a question regarding IP Summaization: Up untill today I thought I had summarization down cold until I tried a few self made excercises. The formula I used to gather a summ address was 2n=x. Thats 2 to the n power equals x. x is the number of subnets that you want to summarize and n will be how much you subtract from the lowest mask of those subnets. for example: 216.52.146.136/30 216.52.146.140/30 216.52.146.144/30 216.52.146.148/30 using that formula the summ would be 216.52.146.136/28 which is not a valid route. Hoever that formula works here: 216.52.146.48/29 216.52.146.56/29 summ route: 216.52.146.48 /28 I guess my question is, what is the best/effective/convient way to derive summary addresses? Thanks for any input.

RE: PPP on 2514 [7:41973]
If the ISP indeed gave you a /30 for the PtP and a subnet for your internal hosts (which it lookeslike they did) you can still use your insde 192 addresses on the inside. Take the 164.65.13.89 255.255.255.252 and assign that to the loopback 0 interface and use that address to NAT to. This way the world will see all of your internal IP hosts as 164.65.13.89. Hope that helps.

Great example, however let me make sure that we all aware of the terminologies, and correct me if I am wrong: Feasible Successor's are next-hop routers that advertise a routes towarads a given destination Successor\s are the choosen next-hop router\s towards a given destination Feasible Distance is the lowest calculated metric towards a given destonation Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=42005t=41957 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
