[Lab environment] Cisco Packet Tracer 5.3.2 [PURPOSE] Exercise the use of the ip default-network command to declare the default route in the network routing protocol. [Experiment topology] [Lab description] Vrogw GW and ISP refer to the default route to simulate the network between the gateway and the carrier. The VPN protocol is only deployed in the network. The loop 0 interface on the router ISP simulates the external network (1.1.1.1) Generally,

) forwarding to sendFlags: FlagsU up indicates that this route is currently in the boot stateH host, which indicates that the gateway is a hostG Gateway, which indicates that this gateway is a routerR reinstate route, re-initialized with dynamic routingD dynamically, this route is dynamically written toM Modified, this route is dynamically modified by the route daemon or director! Indicates that this route is currently in a closed stateIface: interface for this route-passing packet2. Delete/Set

1. Add a default route Route add default gw 10.0.0.1 (effective only in memory by default) You can append the file to/etc/rc. local at startup. Echo "route add default gw 10.0.0.1">/etc/rc. local 2. Add a static route Route add-net 192.168.2.0/24 gw 192.168.2.254 To take effect permanently, do the following: Echo "any net 192.168.2.0/24

-broadcast-reply" packet is received Is there a problem with this mechanism, or the design of ARP? Principles of ARP Spoofing We have learned from the article ARP working principles that the host will save and update the local ARP cache table in two cases,1. When receiving the "ARP broadcast-request" Packet2. When an "ARP non-broadcast-reply" packet is received We can see that the ARP Protocol has no authentication mechanism, and any host in the LAN can forge ARP packets at will. The ARP protoco

paper is mainly used Siamese network face similarity discrimination, can be used for face recognition oh, because I think this document network structure of the picture is relatively beautiful, easier to understand, so use this article, a simple explanation of the idea of Siamese network. Its network as shown, there are two branches to enter the picture X1, X2 (Note: These two branches are actually the same, the same CNN model, the same parameters, the literature is only for the convenience of

In the daily use, or in the server, there are two network cards configured two addresses, access to different network segments, this situation is very common phenomenon, but, We need to add additional routing tables to determine which packets are sent through the correct gateways and interface to communicate correctly today to introduce how to add routes in the Linux operating system (mainly for Rhel series, test Platform for rhel5.4)One, add temporary routes to the host by using the route comma

Find a good example of learning Bat program code to share with you, the specific code is as follows: @echo off Route print-4 "10.0.0.0" | find "10.0.0.0" > Route_list set gw= for/f "Tokens=1-5"%%a in (' Typ E route_list ') do ( if not%%c "= =" (set gw=%%c) ) if "%gw%" = "" (echo "fail to get eth0 default GW" am

=100basetx-fd eth0. Add this command to the system startup script so that it is always valid so that the NIC automatically locks to 100basetx-fd each time it starts.(5) Configure static routing: Using the route command, the basic format isRoute add [-net|-host] target [netmask Nm] [GW GW] [metric N] [[Dev] iface]Route del [-net|-host] target [GW

Each host has its own routing table #route-N View routing Information 0.0.0.0 is the default routing information. The method for modifying the default routing information is summarized as follows: 1. Use route command to delete # route del-net 0.0.0.0 netmask 0.0.0.0 or # route del default # route add default GW 192.168.16.1 dev eth0 Then restart the Network Service network restart 2.
