I am currently reading the the network layer chapter in Kurose & Ross Computer Networking: a top down approach. The UDP segment is carried between routers in a standard IP data- gram. TLDR: How do routing protocols like OSPF and RIP use the network layer if they themselves are required for the routing of the network layer?
In a single AS network that provides both L2VPN and L3VPN services, how should routers be managed by administrators and operators? Should they access the routers loopback interfaces via pure L3 routing to establish SSH connections, or should a separate dedicated VRF be allocated so that they connect to the loopback through an L3VPN?
in a Cisco environment , can you change routes to a network 1.1.1.1 on a Cisco router depending on which source loopback you use on that router without using PBR (Policy Based Routing ) ? so if i have a network 1.1.1.1 so if i have a network 1.1.1.1 any help would be appreciated , thanks !
Im setting up a network where multiple subnets share a single DHCP server. The router can ping the DHCP server, but end devices connected to the router cannot obtain an IP address. Heres my setup and what Ive tried so far: Network Setup: DHCP Server: IP: 192.10.0.2 Main Switch: Connects to the DHCP server and all routers.
I have to design a network where there are 4 within which are different number of VLANs with varying number of hosts per VLAN depending on the building. My confusion lays in the main router, does it have to be in a subnet all of its own? and so forth?

I have a comcast business router and the only thing behind it is an unmanaged switch. All of the IP addresses on my PCs are 192.168 but when I log into the router everything shows 10.0 I wanted to setup static IPs because I'm having some trouble on the network with printers but struggling with this IP addressing issue.
I'm not a network engineer, but I play one at work. :D I'm trying to connect our test kiosk to the wifi network. I have a wireless router on which I've installed dd-wrt. I have a wireless router on which I've installed dd-wrt. The plan was to use the router as a wireless bridge to my lan.
It must support several 48-96 ports switches/routers. What tool do you use to keep your network documented? I'm looking for the best tool/website to keep the information of all my devices, the connection, the location in the rack, the number of rows.
I need to test a router and see for example how many OSPF neighbors, routes, areas, the router supports. Do you know any scalable open-source option for this purpose? I encountered BIRD which I guess is scalable but it doesn't support IS-IS for testing. Any help is appreciated.
Juniper Networks , a provider of secure, AI-native networking, has today announced a landmark project with the Netherlands Institute for Radio Astronomy, ASTRON, to upgrade its core, access, WLAN and WAN network infrastructure, supporting the development of its LOFAR 2.0 (Low Low Frequency Array) upgraded telescope.
In part 1 of this series , I talked about the importance of network observability as our customers define it — using advances in data platforms and machine learning to supply answers to critical questions and enable teams to take critical action to keep application traffic flowing. Access and transit networks, edge and exchange points, CDNs.
One of my biggest challenges here is determining how to establish an overlay network over the WAN. Another challenge is that the network infrastructures in SITE A and SITE B share the same IP blocks, and I cannot change them. How can I configure this network without causing any IP conflicts? 24 | [Router C] | 192.168.3.0/24
The Problems (1) I have two routers, a Zyxel C3000Z (Centurylink) and a Netgear Genie WNDR3400v2. 251,222,250 for my PC ,TrueNas Server and Netgear Router respectively. 1 I setup the TrueNas (A Dell Studio 540 with a 1000BaseT Network capability) and connected it to the Netgear Router. Default Gateway is 192.168.0.1.
I have this network when the network tries to communicate with the routers it fails. Router>enable Router# Router#configure terminal Enter configuration commands, one per line. Router(config)#interface GigabitEthernet0/0 Router(config-if)#ip address 172.17.2.1 Press RETURN to get started!

I need help on finalizing the Network Scheme for a Warehouse. They are always connected to same WiFi Network. Current System has 2 different ISP with total 6 wifi access point for 3 each since it's large Warehouse Each ISP has 3 WiFi access points for connectivity. I tried reading for SD-WAN but not sure if it's a good idea.
For reasons that are not important, we have a customer that wants to ensure that it can not work on an actual IP network and only direct. But, when I connect them through our corporate network, through multiple switches, managed and unmanaged (and possibly a router, I didn't check with IT), they still link together and function normally.
I have a router that uses a SIM card for connectivity, and I create a socket connection. After the connection is disrupted, when I attempt to send a packet from the server using the previously established socket, the router responds with a RST (reset) packet. I have checked the firewall of the router but it seems to be deactivated.
and everything else on this network From Site A, I can only ping 10.0.3.1. SITE B Secondly, I'm going to be connecting up a VOIP/SIP network onto this router for Site B. network? Need help here Site B TZ105 x0 Lan 192.168.162.1 X2 LAN 10.0.3.1 Site A TZ300 X0 LAN 10.0.1.1 From Site B I can ping 10.0.1.1
I got a router on a stick and I want to optimize it by reducing its cost and also the configuration costs This topology is to facilitate inter Vlan routing so Vlan1 can communicate with Vlan2. PC0 and PC1 are on vlan1 and PC2 and PC3 on Vlan2. The question is how will this topology be optimized. The topology is illustrated in the figure
I'm encountering a puzzling issue with OSPF adjacencies in a mixed network environment and would greatly appreciate any insights or suggestions. Network Setup: Devices Involved: A Cisco 2900 router. Topology: The virtual Layer 3 switch is connected to the physical network via a hub. Router Priorities: Properly configured.

My Router shows its SSID when I browse the network but doesnt connect. The router has a fibre connection (1000mbs) and Ethernet works but not WiFi. There is a VPN router using this router to backhaul to the internet. The WiFi on the VPN router works OK. Fibre router IP is 192.168.18.1
Outlined in light blue is the hybrid cloud which includes the on-premises network, as well as the virtual public cloud (VPC) in the AWS public cloud. In both hybrid and multi-cloud configurations, all of the customer data stays private and cannot be accessed via the internet unless the network team chooses to do so. VPCs and Security.
Traffic telemetry is the data collected from network devices and used for analysis. As a critical input to a network observability platform, this data can help monitor and optimize network performance, troubleshoot issues, and detect security threats. Monitoring network traffic can be expensive.
Using ClI/SNMP it can be collected, but route table ia big and taking more.time, also let ad router. May be peering can be useful to collect, but all the router in the network to be peered. Syslog/Trap enabling for route changes will not capture the entire entries.we.need.aging details also.
Starting from the following network topology: Internet ISP Cable Router Firewall Router rest of the network / multiple VLANs (port forwarding) | DMZ I had to expose two VLANs over the internet through VPN for two groups of users. what is the recommended way of achieving what I want to do?

In our conversation today with CTO Cameron Daniel of Megaport, we discuss their global WAN architecture, PoPs, use cases, the Megaport Cloud Router, and more. It’s accurate to describe Megaport as providing Network-as-a-Service. It’s accurate to describe Megaport as providing Network-as-a-Service.
When evaluating solutions, whether to internal problems or those of our customers, I like to keep the core metrics fairly simple: will this reduce costs, increase performance, or improve the network’s reliability? It’s often taken for granted by network specialists that there is a trade-off among these three facets. Durability.

If I assign a static IP on the device level that is within the DHCP range of the network it's on, but don't reserve its address on the DHCP server, will the device lose its IP address or be disconnected if the router restarts?
As such, routers are put in layers. The first layer is the edge of the internet (connected to the internet gateways), hence those routers typically are called "edge routers". The deepest ones are in a layer, called the backbone, and those routers are called "backbone routers".
