Digital Certificate – Public Key Infrastructure Concept

Personal-Web-Certificate

Digital Certificate adalah suatu identitas “objek” yang menyatakan bahwa yang melakukan transaksi kala itu ya benar-benar objek yang bersangkutan.

Pendekatannya seperti Kartu Identitas. Ada Certificate Authority (CA) yang ‘berdaulat untuk mengeluarkan certificate. Ada subscriber, yaitu “sesuatu” yang me-request certificate ke CA.

Nah, pendekatannya tadi kan Digital Certificate ~~> Kartu Identitas. Jadi ceritanya misal ada suatu server, mau bikin service HTTPS, perlu Certificate untuk Site HTTPSnya, maka dia akan me-request certificate ke CA. Dia akan membuat request (ibarat proposal) yaitu suatu CSR (Certificate Signing Request) dan Private Key sebagai pasangan CSR ini. CSR adalah request yang akan dikirim ke Continue reading “Digital Certificate – Public Key Infrastructure Concept”

[ASK ME] Network Design Consultation & Deployment Services

Network-Design-hand-drawing

Let me suggest you about your network design solution. It is Free!! or you can donate a few 🙂 . The main purpose is i want to try help you solve ‘the need of your network’ while increasing my network design skills & experience.

I experienced in a bonafide Service Provider as Network Technician & Representative Network Engineer, handling project to design and deploy insurance office network in Jakarta. Hold a Cisco Certified Network Association Routing Switching (CCNA-RS), Mikrotik Certified Network Associate & Routing Engineer (MTCNA, MTCRE). Visit my resume on LinkedIn.

If you interested to talk about your network planning, design and deployment, or need training about Network Fundamental, preparation for your CCNA exam, you can contact me through my email at me.agussasmito[at]gmail[dot]com

Static Route on Mikrotik, Juniper, Cisco IOS, IOS-XR, Linux & Windows

Fikiran lagi rada tumpul nih, pengen belajar ini itu tapi waktu rada ngepress, jd kepikiran command-command kalo di beda platform kek gimana sih. Sebenernya secara konsep semua sama, define tujuannya (destination), lalu define lewat mana (gateway), cuma beda model penulisan & command doang..haha… Oke Lansung this is about “Command Concept” of configuring static route :

1. Static Route on Mikrotik

Base command = ip route add dst-address=[destination][/prefix] gateway=[gateway]

Contoh :

ip route add dst-address=192.168.199.0/25 gateway=1.1.1.1

ip route add dst-address=192.168.199.199 gateway=1.1.1.99,1.1.1.1

ip route add dst-address=0.0.0.0/0 gateway=1.1.1.1

ip route set 0 gateway=1.1.1.1,1.1.1.99   ——>> default route

2. Static Route on Juniper

Base command = set routing-options static route Continue reading “Static Route on Mikrotik, Juniper, Cisco IOS, IOS-XR, Linux & Windows”

eBGP Physical Peering on Cisco IOS-XR

conceptYaakkkk…… EBGP Peer on Cisco IOS-XR. Agak beda dikit disini woi sama di cisco IOS based. Pertama kali konfig EBGP di IOS-XR “loh.. kok state/prefixreceivnya !0???!! ehhh usut punya usut ada yang beda EBGP peering di IOS-XR. What is that? cekidott… 🙂 Continue reading “eBGP Physical Peering on Cisco IOS-XR”

iBGP Loopback Peering, Router Reflector & Neighbors Grouping on Cisco IOS-XR

yeayWhy Loopback Interface for iBGP Peer? Loopback interface will “never” down although physical interfaces are down, that’s why it will be better we use Loopback for iBGP peering in a network which have multiple path redundant link, it make your BGP Neighborship more stable  with it redundant link than use physical peering. It’s will be so sensitive in ‘need high-availability’ network, like BGP for MP-BGP in MPLS Networks 🙂 (betol nggak tuh aku pake grammarnya??haha Continue reading “iBGP Loopback Peering, Router Reflector & Neighbors Grouping on Cisco IOS-XR”

IPv6 Routing – Static Routing

Topologi Lab : 

topo

Metode Lab :

  • Buat topologi seperti diatas, kemudian konfigurasikan IP Address pada interface sesuai pada topologi.

 Verifikasi Lab :

  • Pastikan IDN-R1 bisa ping ke IDN-R3 dan sebaliknya
  • Konfigurasi static route pada IOS-XR tidak jauh beda dengan IOS biasa.
  • Kalau di IOS biasa pakai ip route… atau ipv6 route…., di IOS-XR menggunakan address-family
  • Penulisan dapat dilakukan sekaligus dalam satu baris atau dibuat terpisah berdasarkan konteks (Separate tree). Continue reading “IPv6 Routing – Static Routing”

iBGP Physical Peer on IOS-XR

IOS-XR again, now about iBGP peering with physical interface IP address. I just using 2 routers in this lab, just peering, no RR, no Confederation, i will post later about RR a.k.a Route Reflector in iBGP. (ceileeehhh…. sok inggris..wkwk)

Jadi Lab kali ini cukup sederhana, cuma 2 biji router cisco IOS-XR based. Nanti silahkan dibandingkan what is the different between configuring iBGP in IOS and IOS-XR (kalo ada bedanya sih..haha…). Skenarionya JOGPOP-XR1 peering ke JKTCBR-XR1. JOGPOP bakal ngeadvertise semua connected networknya, sedangkan JKRCBR hanya akan mengadvertise network 2.2.2.2/32. AS Number yang kita pake adalah 4800 [hayo ASNnya siapa tuh??haha.. ceritanya nostalgia masa lalu :3 ] . Topologi seperti ini nih :
