		<title>Self-ping over PPPoFR links</title>
		<description><![CDATA[This post was created as a result of a recent groupstudy post regarding self ping over PPPoFR links.
Typically, when you create a PPPoFR link between a pair of routers, you can ping the remote end, due to peer neighbor route.
However you can&#8217;t ping your OWN interface ip.
Consider the following scenario.
R1 s0/0.12  &#8212;&#8212;&#8212;&#8212;&#8212; s0/0.21 R2
There is [...]]]></description>

This post follows on the back of my previous blog entry:

		<title>RIP updates over pt2pt serial: a few methods</title>
		<description><![CDATA[Spoiler alert: If you are doing Narbik&#8217;s new RIP lab, then please do that 1st before looking at this, otherwise it will just spoil things.
Ok let&#8217;s say you have this scenario:
R1 &#38; R2 are connected via a serial link.
HDLC is running over this link.
You can NOT change the encapsulation over this link (ie. no enc [...]]]></description>

		<title>Redistribution &#8211; Narbik Lab &#8211; be careful!</title>
		<description><![CDATA[This example is taken from Narbik&#8217;s workbook on redistribution.
For those who don&#8217;t have Narbik&#8217;s workbooks &#38; can afford to obtain them (they are great value) &#38; have the time to do them, I thoroughly recommend them  
Anyway, this tutorial is a great example in being CAREFUL, &#38; rechecking the task to ENSURE you have [...]]]></description>

		<title>OSPF Incompatible Network Types + GRE</title>
		<description><![CDATA[With incompatible network types, if the hello/dead timers match, we can get the OSPF adjacency to form BUT no OSPF routes will be installed.
Consider the following topology:
R1 s0/0.12 &#60;====102===201====&#62; s0/0 R2
R1 &#38; R2 are connected via a frame relay PVC.
R1 s0/0.12 &#38; R2 s0/0 are both in OSPF Area 2.
Configs:
R1
interface Serial0/0.12 point-to-point
ip address 10.1.12.1 255.255.255.0

		<title>The joys of the Debug condition command</title>
		<description><![CDATA[Say you are running RIP, &#38; you wish to debug ip rip.
Typically you will see every 30 seconds a barrage of output from the debug.
If you are only interested in seeing the debug on a particular interface/subinterface, this is where debug condition helps.
So say we have R1 with the following interfaces all running RIP:
R1#sh ip [...]]]></description>

		<title>Status Update</title>
		<description><![CDATA[Hi all
Studying for the R&#38;S, at times has had to take a back seat to my job hunting.
My contract is ending somewhat shortly so I am on the lookout.
Anyway, I am continuing to progress through Narbik&#8217;s workbooks.
Progress is slow, but sure. Like Nickelby I am making sure I understand what I am doing.
I am also [...]]]></description>

		<description><![CDATA[To start off with, I&#8217;d like to give thanks to Stuart Juggins of Networks Inc, who helped make this possible.
Stuart approached Narbik and managed to get him to come over to the UK and teach here.
Thanks Stuart!
I had always wanted to attend Narbiks bootcamp due to all the great things I had heard about it, [...]]]></description>

		<title>Narbik&#8217;s bootcamp Day 2</title>
		<description><![CDATA[Today Narbik covered OSPF &#38; EIGRP.
I have to say, I did learn quite a bit today.
Now I thought I knew these topics to a fair degree, but every time Narbik starts talking about stuff that makes me question what I really do know.
This is a good thing. We are here to be challenged, to learn [...]]]></description>

Quite a day it was, running from 9am till 9pm-ish.
We were all delayed at the beginning of the day due to idle timeouts to the terminal server.
For users of securecrt under session options, its pretty eas to resolve this&#8230;just send a character every 5 secs or something.
