I understand what the command does.... I have my home lab and want to make sure that I past the configs in exactly so that I can see the troubleshooting issue as if I'm working the actual time in my upcoming lab... the problem is.. when I paste the command, it not accepting it, and when I hit the question mark... its asking for internal or external ?
Question for the IPExpert Team... which route do you want this command to block are part of the trouble ticket ? ( internal or external) I'm not trying to over think it.. but looking for an answer to a simple question ... ________________________________ From: Nilesh Mehta <[email protected]> To: Cedric King <[email protected]> Cc: Roy Waterman <[email protected]>; "[email protected]" <[email protected]> Sent: Sun, April 10, 2011 3:42:36 PM Subject: Re: [OSL | CCIE_RS] Lab 1 vl 3 When you create summary routes in OSPF by default it will also create summary route to null 0 interface to prevent routing loop.Now in the lab they have issued no-discard-route command on R4 so it will not create summary route to null 0 interface and so that way nasty routing loop is created in this trouble ticket.Basically discard-route is feature in ospf . Its not external or internal routes and by turning off this feature in trouble ticket they have created routing loop. Hope this will help you.... Onceyou understand this you have 2-3 different ways to resolve this TT which explained in DSG very well Thanks.
