Earlier I have done some posts on route redistribution and on route filtering in different protocols. I wanted to expand on this by showing different ways we can tag and do filtering with route-maps when doing route redistribution. We start
100k views – Thanks for visiting!
This site just hit 100 000 visitors! I have been blogging for roughly 2 years now and I never expected the site to grow to the size that it has today. Unfortunately I don’t have the CCIE yet but I
RIP – request and response packets
I was discussing the other day with someone on IRC about a RIP issue he had. Apparently he had RIP request packets coming in and then all routers were responding with response packets with full routing table. It seemed like
RIP MD5 authentication – mismatch in key ID
This is an interesting fact I just found out. When we configure MD5 authentication for RIP they key-ID and key-string must match, this is well known. But what happens if we actually configure the wrong key-ID? Take a look at
OSPF – Use of forwarding address
In OSPF and other routing protocols we have something called forwarding address. This can be used to route traffic in another direction than to the router that originated the LSA. We start with the following topology. It’s a basic OSPF
Some interesting facts of OSPF
OK so clearly I haven’t been updating a lot lately due to my very busy situation. I’m sorry for that but my former colleague Henri keeps nagging me for an update so I decided to write on some interesting tidbits
OSPF: Anatomy of a routing protocol
To become a CCIE you need detailed knowledge of OSPF. Most candidates will have read the TCP/IP Volumes by Doyle and maybe even the RFC written by J Moy. This book is also written by J Moy and it is
Cisco Live – Great resource for CCIE studies
Hey guys, I’m at home enjoying the time with my family which as you have seen has just grown with a new member 🙂 Cisco Live US was just held in San Diego and now the sessions have been uploaded.
More on SSM
As you’ve noticed I’ve been studying SSM and what better way to learn than to blog about it. I recently got a Safari subscription which has been great so far. I’ve been reading some in the book Interdomain Multicast Routing:
Multicast – SSM mapping
This is a followup post to the first one on SSM. The topology is still the same. If you want to find it in the documentation it is found in the IGMP configuration guide I guess the reason to place
