Here are sample static route configuration on Juniper routers such as MX and QFX series. 1.Configure IPv4 default route to next hop 192.168.10.3 set routing-options static route 0.0.0.0/0 next-hop 192.168.10.3 2.Configure IPv4 default route to next hop 192.168.10.3 via management port set routing-instances mgmt_junos routing-options static route 0.0.0.0/0 next-hop 192.168.10.3 3. Configure IPv4 for 192.168.0.0/16 range to Null interface (e.g. for BGP advertisement) set routing-options static route 192.168.0.0/16 discard 4. .Configure IPv6 default route to next hop…

It is recommended to implement the separation of management and data/customer traffic in your Datacenter switches like Cisco IOS and IOS-XE (e.g. ASR1000). Traffic passing through the management plane should be exclusively for management or administrative access purposes only like SSH, SNMP, NTP and AAA. Here’s the recommended configuration or practices for these management services. Configure Authentication, Authorization and Accounting (AAA) -preferably to setup centralized TACACS+ to manage all your devices, some uses Cisco® Identity Services Engine (ISE) for central…

These are the some commands being used when performing network change or maintenance, depending on the features or services being run in the network. Typically, this is very useful in verification, troubleshooting and comparison between before and after the change. #Log Time set cli timestamp set cli screen-width 200 show ntp associations no-resolve | no-more show ntp status no-resolve | no-more ## Hardware Status show chassis hardware | no-more show chassis hardware clei-models | no-more show chassis hardware detail |…

Fiber Optic Transceivers are wavelength-specific lasers that can convert electrical data signals into optical signals via optical fiber. It is basically a device that uses fiber optical technology in sending and receiving data. Here’s the classifications: Based on form factors 1. XENPAK – original 10G pluggable optics using SC connector type 2. X2 -provides 10G connectivity up to 40km on SMF and successor of XENPAK. Also used SC connectors 3. GBIC -short for Gigabit Interface Converter, is a standard…
Autonomous System or AS is a set of routable IP prefixes that belongs to a network or collections of networks managed by a single entity such as ISP, corporate network, university, etc. and maintain a single or common routing policy. Each AS has to be represented by unique number called Autonomous System Number or ASN to control and exchange routing information with others. Two formats of ASNs: 2-byte ASN (16-bit number) –> provides for 65,536 ASNS (0 to 65535) .…
Fiber Optic Cable Connectors provide alignment of microscopic glass fibers used in fiber cables in transmitting high speed data. These are the types of fiber optic cable connectors that you will come across in a datacenter. There’s few more that I excluded in the list as already obsolete and seldom use. 1. SC (Standard/Subscriber/Square Connector) -most popular type used in telecomm/datacomm industry for its durability, low-cost and simple installation. It uses locking tables and classified as push-pull connectors. -ferrule diameter…
