Trying out Multicasting !!

Alright its finally time for me to play around with multicasting :)
First off I tried configuring PIM-Dense mode, pretty simple & straight forward with a four router topology !! Then moved on to PIM-sparse mode. Configured the RP for particular groups. Tested the multicast routing .
The show commands are pretty cool I would say.
The mtrace & mstat are kind of cool commands to find out the RPF path.
Good stuff but not enough. So let get rocking from tomorrow.

Well I have delved into the world of multicasting & not very comfortable @ the moment but will be very soon :)

c ya !!

Finally ... Through With Multicast Theory !!

Alright, Finally I am done with the multicast theory. Only the "Anycast" theory is still pending. I thought I will breeze through it when am doing the practical part.
Man it was some heavy stuff !! Got to admit though interesting the vastness of the theory got me sleeping many a times. :)

Well all said & done now I have to to get to the practical part. Well I am close to 30 hours behind schedule & have to get back on track. QOS is on my mind after EIGRP.

Lets hope we get back on schedule else I will dum EIGRP & get to QOS because of my weakness. I am sure I will get my core IGP & BGP working in the lab no matter what they throw @ me . Well I might get started on the basic configurations today itself(just my excitement getting to me :)).

Alright well done one week spent to get the Muticast concepts right.
Got to go through the DOC CD as well which I think I can do while at work to give my self something to work on.

Alright then lets get started with the basics of Multicasting :)

Multicast Routing & Me

Well I should say that Multicast routing is not bad after all. Well it does have a looooot of theory even when I am revising . In a way am happy with my approach , now that cisco has announced the open ended questions before the ccie lab exam, its good that I take my time to read through the concepts as a revision. I would say time well spent :)

So am on to the large scale implementation & am having this nasty cold. Nothing is gonna stop me now & off I go !!

Adventures of Multicast Theory !!

Well Sunday sure went fast !! I was on to the Multicast theory part.
I should say its is quite interesting, although it does involves lots of theory.
I will finish PIM-SP tonight & hit the sack, so that I can start off with the configurations section from tomorrow. I would really love to revise the whole section, if time permits in office I will just brush through all the concepts before we head off to the configuration section.

Tomorrow's plan stands as follows:



I will have to go through the Doc-CD also & pick up stuff I might have missed.

I am on leave on 13Th & 14Th. I hope to cove maximum topics by this time period.
I am really happy am able to bring in my focus & concentration. I just hope I am able to put in 6 hours daily ;)

PIM-SM here I come !!

Over to Multicast Routing

Well to get way from the heaviness of BGP am switching over to Multicast Routing !!
I have altered my calendar also. Well every day is now becoming critical.

The CCIE Blue print reads;

IP Multicast

1. PIM-SM, bi-directional PIM
2. MSDP
3. Multicast tools, source specific multicast
4. DVMRP
5. Anycast

So am just starting off with the cisco press Routing TCP/IP Volume 2 book.

This is one of the concepts which am not good at. Hoping to make a good deal of progress today. Hope to cover the following topics today;




IE mentions the following topics to look out for.

* IGMP
o Join
o Static
o Access- Group
o 3560 Profile
o Helper
o Timers
o Max Groups
* PIM
o Sparse
o Dense
o Sparse-Dense
* Reverse Path Forwarding
o Static Mroute
* RP Assignments
o Static
+ Specific Groups
+ Override
o Auto-RP
+ Sparse-Dense
+ Auto-RP Listener
+ Default Static RP
+ Specific Groups
+ RP Announce Filter
o BSR
+ Specific Groups
+ Priority
+ BSR Border
* NBMA Mode
* Stub Routing
* Shared/Source Trees
o IP PIM SPT-Threshold
* Multicast over GRE
* TTL Scoping
* Multicast Rate Limiting


I think I might have to pick up couple of other books also to understand the concepts. Well right now am tensed, why because have gots to work @ !!

Got to go study !!

Managing BGP Connections

I went through setting up BGP neighbor description & BGP neighbor passwords.

BGP Neighbor Description

The BGP Neighbor Description is just for your use to understand in a later point of time what you are dealing with & is very simple to configure;

R0(config)#ip routing
R0(config)#router bgp 100
R0(config-router)#neigh 10.1.10.1 remote-as 101
R0(config-router)#neigh 10.1.10.1 description connected to right side router
R0(config-router)#end

R0(config)#ip routing
R0(config)#router bgp 100
R0(config-router)#neigh 10.1.10.1 remote-as 101
R0(config-router)#neigh 10.1.10.1 desc
R0(config-router)#neigh 10.1.10.1 description connected to right side router
R0(config-router)#end

BGP Neighbor Password

Setting a password is also very simple & neat. Al you do is set the password & poof you have secure BGP connections. MD5 hashing is used.


R0(config-if)#router bgp 100
R0(config-router)#neighbor 10.1.10.1 password cisco
R0(config-router)#end
R0#
*Mar 1 00:31:12.555: %SYS-5-CONFIG_I: Configured from console by console
R0#
R0#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R0(config)#int s0/0
R0(config-if)#no shut
R0(config-if)#end
R0#
*Mar 1 00:31:54.275: %SYS-5-CONFIG_I: Configured from console by console
R0#
*Mar 1 00:31:55.835: %LINK-3-UPDOWN: Interface Serial0/0, changed state to up
R0#
*Mar 1 00:31:56.839: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
*Mar 1 00:32:07.711: %BGP-5-ADJCHANGE: neighbor 10.1.10.1 Up
R0#
*Mar 1 00:33:08.375: %TCP-6-BADAUTH: Invalid MD5 digest from 10.1.10.1(179) to 10.1.10.100(12605)
*Mar 1 00:33:10.055: %TCP-6-BADAUTH: Invalid MD5 digest from 10.1.10.1(179) to 10.1.10.100(12605)
*Mar 1 00:33:13.135: %TCP-6-BADAUTH: Invalid MD5 digest from 10.1.10.1(179) to 10.1.10.100(12605)
*Mar 1 00:33:19.275: %TCP-6-BADAUTH: Invalid MD5 digest from 10.1.10.1(179) to 10.1.10.100(12605)
R0#

The message keeps popping until the other side is configured with the same password.
An interesting thing to note was that space is accepted in the password. so be careful when you issue a ? to see further options. i hit the point where a BGP notification was sent even though the password matched or @least appeared to have matched that's when I realized is had checked for context sensitive help & left a space in the end :)

CCIE RoadMap BGP -1

Well I have Planned out my schedule for this month & trust me its quite a hectic one.
Anyways I will post my Google calendar here & share what I am up against [:)]
Here's me wish myself all the best before I embark on this months journey.
For now got to hit the sack

My Technicality !!

I have 2.5 years of experience with cisco gear & networking, I am a CCNP & have finished my CCIE written. I have been preparing for my CCIE lab since November. Currently, I am working on BGP. I am just reading through the cisco press Routing TCP/IP Volume 2 book to refresh my concepts. The best ccie books for preparation would say.

Apart from that I am using Internetwork expert volume technology focused labs to become strong. I preferred them due to the sheer number people referring them as great content deliverers & its very affordable. I am looking forward to attend their infamous ccie boot camp. There are multiple vendors who are believed to be the best for ccie bootcamps such as narbik, IE.

So lets get on with our ccie prep !!

The Grand Introduction !!

Hi,

I finally set myself a blog to key in my CCIE journey in the year 2009 !!
Will make this blog as interesting as possible both for myself & for the readers of this blog.

Feel free to mail me & join in as a study bud if you are seriously studying for your CCIE R&S !!

Wishing everyone around the world & myself a very happy & prosperous new year ahead !!

Let the Show Begin :)
