Passive Option in BGP ! Looks interesting !

November 9, 2011 No comments

Hello ,

I was doing some Basic Bgp Stuff just to free my hands on a deployment. I have found an option under BGP “Passive” which is interesting

Go through the documentation here. I promise its very simple ! ;)

http://www.juniper.net/techpubs/software/junos/junos95/swconfig-routing/id-13320480.html

Here is the lab output which i have for the option.

The passive option is configured on the other end of the router , which i dont have access right now , will update accordingly

Vpls -> Have done this on one router with multiple back to back looping of interfaces

November 9, 2011 No comments

Hello All,

Most of you Know what is a VPLS and how it works. For that we would atleast would require a 5 router topology. Where in you will have 3 routers in the core one router for the Ce side and other router should be on the other side.

I have taken one the MX240 and made with 5 loops which makes VPLS possible on only one router. Here is the below config / Outputs which explains the same.

===================================================================================
Topology

CE1——PE1——-P———PE2———CE2

Loops
—–

ce1-pe1 (ge-1/2/3—ge-1/2/0)
pe1—-p—pe2 (ge-1/0/0—ge-1/0/3)
ce2-pe2 (ge-1/1/6.0—ge-1/1/7.0)

This lab aims at setting up vpls between Two Pe routers and as a result ospf between Two ce’s

Automate your login for lab devices if you are using Secure CRT and setting the cli time stamps

September 25, 2011 No comments

Many of you might have known it , yet for the unknown I am Forwarding it as I found it interesting

Purpose: If you are using Secure CRT , on telnet to your device you can automate the entries of “login name” and “password” Fields without you typing it for each session.Later with the use of a Vb script you can actually record timestamps for all the actions on the terminal itself

Benefit: Time saver
