1.1.d TTL

from routing tcpip vol 1…

If the router is told to trace the route to a host address such as 10.11.12.13, the router will

send three packets with the TTL set to one; the first router will decrement it to zero, drop the
packets, and send back error messages to the source. By reading the source address of the
error messages, the first router on the path is now known. The next three packets will be
sent with a TTL of two. The first router decrements to one, the second to zero, and an error
message is received from the second router. The third set has a TTL of three, and so forth,
until the destination is found. All routers along the network path will have identified
themselves.

In the network diagram, Area 1 is defined as a stub area. IGRP routes cannot be propagated into the OSPF domain because redistribution is not allowed in the stub area. However, if we define Area 1 as NSSA, we can inject IGRP routes into the OSPF NSSA domain with the creation of type 7 LSAs. Redistributed RIP routes are not allowed in Area 1 because NSSA is an extension to the stub area. The stub area characteristics still exist, which includes no type 5 LSAs allowed.

Hello Arteq and all,

I heard you were asking about a new edition of the CCIE R/S written cert guide! First, I had to make sure I could speak about it. Most of the time, whatever I’m working on is under NDA until long after my part of the work is done.

Anyway, a new edition is on the way, but I’m not involved. My schedule just didn’t work out to do the work, so I am officially out of the loop on the book.

As for the book itself, I just spoke with Brett Bartow, Cisco Press Executive Editor who’s working the book, and the current schedule shows the book available by Cisco Live in San Fran, early May. Note that any book avilability date that’s 6 months out is tentative – probably means the manuscript is just wrapping up, with some edit passes left, and much production work remaining. The book is in good hands, but I’ll leave the announcement details to Cisco Press. If I see anything interesting that doesn’t get posted over to this group, I’ll pop over and add it.

Bruno’s already posted a list of all the new Cisco Press titles related to the new CCIE R/S blueprint here, with the current estimated dates.  https://learningnetwork.cisco.com/thread/64182

I’m looking forward to seeing how the new book turns out!
