menjelang pergantian tahun GMT+7, sedikit menengong kebelakang merenungi perjalanan ku belajar about network, simple world but many mean and many application.
satu kisah yg tak terlupakan di 2008
- kesempatan CCIE lab exam first time
- CCIE lab exam first time failed
- kehilangan kesempatan first attempt pass CCIE lab exam and get #number
benar-benar keputusan yg besar untuk menuju CCIE, apalagi tanpa bantuan dari sponsor atau company, semua dgn swadaya swadana sendiri.
CCIE lab yg dibuat dengan format 8 jam ujian terus menerus praktek, di depan sebuah komputer yg terkoneksi dengan jaringan khusus yg mengakses topologi jaringan sesuai dengan soal, close book, hanya bisa mengakses cisco.com/univercd sebagai panduan. 8 jam ujian lab sangat menentukan dalam hasil namun 8 jam dibandingkan dengan persiapan sebelum ujian rasa2nya tidak ada artinya, harus mengurangi waktu tidur setiap hari, tidak pernah merasa tidur dengan nyenyak, beresiko sering ketiduran waktu kerja :D.
kalau dirangkum kira-kira efeknya seperti ini
1. bisa mengetik cepat, apalagi command2 cisco
2. banyak hal2 yang belum ngerti bahkan belum pernah tahu jadi tahu dan paham
3. semakin dekat waktu ujian, semakin banyak hal-hal yg belum mengerti dan rasanya waktu kurang 24 jam
4. perut jadi agak sedikit buncit, karena jadi makan banyak, sering lapar
5. jadi sedikit kuper, kurang bergaul, jalan-jalan jadi bawa2 ibook, ada sedikit kesempatan buka console telnet terminal-console lab :D
6. kantong jadi bokek, karena harus nabung abis2an buat biaya lab :D, buat beli peralatan lab, kabel2 serial, server simulasi dsb
beberapa jam setelah ujian lab, keluar hasilnya di web cisco dan failed, mencoba menerima apa yg telah dikerjakan dan diusahakan. tidak banyak yg punya kesempatan untuk sampai ke lab exam, meskipun hasilnya failed :D
di akhir tahun 2008, bulan desember tgl 17, sedikit hasil dari usaha belajar juniper network pass JNCIA, tp pass itu tidak lah berarti apa2 tanpa belajar dan terus belajar tentang network. waktu tidak tidur, selalu berputar dan terus berputar dan akan berdampak positif bagi yg bisa memanfaatkan utk hal-hal yg baru dan positif.
tidak ada selamat tahun baru untuk kali ini, karena tidak semua saudara-saudara kita di semua belahan bumi ini menikmati pergatian tahun ini.
bye 2008, welcome 2009.

back ...
It's long time, I'm not post this blog. welcome back ...
So what I do? busy? or stress? because failed CCIE a few month ago no no no. I just little busy for my daily job and busy read what is network from other side :D. So ... really stress with Cisco and change to Juniper ? no no no, I want to know more about network, how OSPF work, how BGP policy apply etc from other side and I choose Juniper. I think learn about network not only from one resource, many resource in this world can be reference and from many company network but still focus. But remember if you're compare network device from different company network doing head-to-head and be fair, not part-of or just half.

Cisco Kron Schedule not Cron Schedule
Do you familiar with *nix Cron Schedule / *nix Crontab Schedule ? How about Kron Schedule in Cisco IOS
Warning be carefull with this example about configure replace at hh:mm
old configure
ip route 0.0.0.0 0.0.0.0 161.1.78.8
new configure (flash:test)
ip route 0.0.0.0 0.0.0.0 161.1.78.8 --> delete it
configure kron schedule
configure terminal
kron policy-list remove-static-route
cli configure replace flash:test force
kron occurrence remove-static-route at 22:49 oneshot
policy-list remove-static-route
step by step, verify, debug
