Hello everyone !
its been a while i wrote to my blog ! Many things happened in the mean while .. first of all i got a job and was busy in adapting to the new role and secondly i went through a very frustrating phase in my personal life and everything was near hell !
Moving on .. well i am done with mcse 2k3 and also planning for mcitp enterprise admin and also speaking of which have other juniper exams remaining which i need to clear up . Dint had any study and i dont know if i can pass them or not
completed some of the link layer technologies and also moving on to labs ..
a detailed excel sheet will be uploaded . You can get it and also make some of your own . excel sheet plan creation is helping me to keep some of the things track down .
Hello all in my certification rush got through some gift vouchers from my friends and went on to attempt my first ever 70-290 just to try my luck .. went through the study guide and poof went through exam .
Hello all two good news to start wtih
Hello guys , i have made a video on deploying and implementing syslog server in gns3 environment . A syslog server logs all messages from routers in gns3 and records them .

Dont know why my mind has been in an unpredictable state .. nothing settling down .. wanted to for jncia-ex as per my last posting .. dint get chance as i was attracted by cisco v4 written beta . done with mpls and ipv6 which were troubling me in two days .. now after that a thought came into my mind to prepare for jncia-ex switching which was obviously easy when compared with other tracks atleast .. quickly went through the study guide ..
Hello myself and another friend of mine are going for our rs studies and were on gtalk last night discussing some multicasting and general prep stuff . I suddenly got an idea on remote desktop and heard about team viewer few months ago. Quickly went to their website and downloaded the stuff .
Hello everyone as you know if i come across any exciting stuff i share with most of you . I happened to get narbik ‘demo’ of his cod which was roughly around 10min on ospf filtering techniques and the entire cod was awesome … In ten minutes he covered most of the info with minute details . The demo vod should be up with in a day or two . can’t wait to get hands on that one as iam going for rs v4 which includes troubleshooting.
for more info you can always visit his site @

will update you if i happen to find any interesting stuff again ..
guday and take care

A sudden catastrophic change of plans has taken place in past 12 hours . i was happy that i got all of the juniper voucher and was about to take jncia-er exam this week until i went to cisco’s website and found that ccie written v4 is now in beta phase and offered for as low as 50$ . Well who wont take that price (atleast students like me ) to go out and take a dreadful exam which was 350$ and that too completely changed with mpls and troubleshooting introduced.
so , cant help for another month . i have been studying stuff seriously .. done with ipv6 stuff and will let you know if possible . iam excited about this beta exam even though i know it would be insanely tough to pass i still give the exam hell before it declares me as fail hehe
Thank you and sorry for change of plans
Topology :
-> minimum of requirement is that there must be multiple routers which are capable of running vrrp in a lan segment.
-> if there are two wan circuits and if there is any routing policy in place which uses only one wan link out of two vrrp should be tuned in such way.
Master or Backup:
->Beefy configuration router is obviously preferred over the non-beefy one as master
-> Assignment of VIP address is one among the important aspects.
Load Balancing:
-> load balancing can be a tricky part . well not let us agree not that hard. assign two routers as masters. assign half routers with one vip address and others with other vip address. Load balancing will be done swiftly.
Preemption:
-> By default preemption is enabled by default. Disable preemption to eliminate unneeded mastership changes during failure and recovery scenarios if you have both routers as masters.
Security:
-> option exists for security vrrp exchanges.
first option : No Authentication
second option : simple text password
third option : most secure : HMAC-MD5-96 (md5)
Avoid Wan link Failure:
-> Either have complete Redundancy
-> Other implement Interface Tracking
