Subnetting table

This document discusses subnetting and subnet masks. It shows the binary and decimal representations of numbers from 1 to 32 and the corresponding subnet masks with bits set from left to right. The number of hosts that can be accommodated on each subnet is shown depending on the number of bits set in the subnet mask, with a higher number of bits set allowing for fewer individual host addresses.

Webinar topic: BGP tuning: Peer with loopback
Presenter: Achmad Mardiansyah
In this webinar, we discussed BGP tuning: peer with loopback. a loopback interface is a virtual interface, which is always ON and will not be affected by physical status. therefore it is very useful to use it as a peering parameter to ensure high availability of BGP peer.

In this webinar, we discussed an advanced topic of mikrotik firewall features: nth packet matcher. we assumed the readers already have a solid understanding of prerequisite knowledge.
we started the discussion with the basic concepts of traffic load balancing, and then move to the nth discussion.

The document summarizes the key features and capabilities of the OptiXtrans E6600 platform:
- It is Huawei's next-generation optical transport platform for enterprises, supporting multiple services including SDH, packet, and OTN.
- It converges 4 services in 1 device and supports interfaces from 2M to 100G.
- It features high integration, huge capacity of over 20T per fiber, intelligent O&M, and simplified network architecture.Simulation using OMNet++

The document discusses simulation using OMNeT++, an object-oriented modular discrete event network simulation framework. It provides an overview of OMNeT++'s core components including modules, gates, channels, and the simulation process. Key aspects covered include writing simulations using the OMNeT++ modeling language NED, defining simple and compound modules, connecting modules with gates and channels, and performing discrete event simulation runs in OMNeT++.pravesh_kumar

In this webinar, we will discuss about the basic concept of routing, try to understand how the router work, how the routing table is used to forward packets, and how to implement them with mikrotik router. we review some prior knowledge before. after attending this webinar, we expect you understand how the packet is forwarded on router.Scaleway Approach to VXLAN EVPN Fabric
Scaleway Approach to VXLAN EVPN FabricScaleway

- Scaleway uses VXLAN with BGP EVPN to build an overlay fabric on their network infrastructure. This provides multi-tenancy, encapsulation of Ethernet frames over UDP, and support for both bridging and routing.
- The underlay fabric uses Clos topology with IPv4 and eBGP for high bandwidth and resilience. Edge devices run as VTEPs to connect virtual networks over the overlay.
- A virtual route reflector provides the control plane for the overlay fabric, decoupling it from the underlying hardware. This allows routing between subnets and multi-homing of hosts between VTEPs.Virtual Routing and Forwarding, (VRF-lite)
Virtual Routing and Forwarding, (VRF-lite)NetProtocol Xpert

VRF-Lite allows a single physical router to virtualize multiple routers by creating independent virtual routing tables (VRFs). Each VRF logically isolates the routing tables and network traffic of customers or applications. The physical router uses VLAN trunking to keep traffic from different VRFs separate when sending data to other devices. Configuring VRF-Lite involves defining VRFs, assigning interfaces to VRFs, and configuring routing protocols for each VRF.VRF (virtual routing and forwarding)
VRF (virtual routing and forwarding)Netwax Lab
油
VRF (Virtual Routing and Forwarding) is a technology that allows multiple instances of a routing table to
co-exist within the same router at the same time. This increases functionality by allowing network paths
to be segmented without using multiple devices. Because traffic is automatically segregated, VRF also
increases network security and can eliminate the need for encryption and authentication. Internet
service providers (ISPs) often take advantage of VRF to create separate virtual private networks (VPNs)
for customers; thus the technology is also referred to as VPN routing and forwarding. Because the
routing instances are independent, the same or overlapping IP addresses can be used without
conflicting with each other.Subnetting Presentation

This document discusses subnetting and provides examples. It describes subnetting as breaking up a large network into smaller subnets. Subnetting allows creating multiple networks from a single address block and maximizes addressing efficiency. The document then provides examples of subnetting a network using CIDR notation and calculating the number of subnets, hosts per subnet, valid IP ranges, and broadcast addresses. It also discusses an example of optimally subnetting the IP addresses needed across different departments within a university based on their host requirements.仆仂仄舒亳仂仆仆舒 弍亠亰仂仗舒仆仂 仆舒 弍舒亰亠 open source: 亠 仍亳 仄仍?

The document discusses IP addressing and subnetting. It begins by explaining how IP addresses are broken into four octets using dotted decimal notation. It then covers binary numbering, IP address classes, subnet masks, and methods for verifying IP addresses including ping, telnet, and traceroute. The goal is to provide an introduction to working with IP addresses and ensure proper network communication.Computer Networking: Subnetting and IP Addressing

The document discusses IP addressing and subnetting. It provides an overview of classful addressing and how IP addresses were originally divided into classes A, B, and C. It then covers special addresses, private addresses, methods for identifying the class of an IP address, network addresses, subnet masks, CIDR notation, and how to calculate the number of subnets and hosts per subnet. The goal is to explain the fundamental concepts behind IP addressing and subnetting.Ip address and subnetting

IP addressing and subnetting allows networks to be logically organized and divided. The key objectives covered include explaining IP address classes, configuring addresses, subnetting networks, and advanced concepts like CIDR, summarization, and VLSM. Transitioning to IPv6 is also discussed as a way to address the depletion of IPv4 addresses and improve security.Ad
