recently discovered that the machine dual-Network IP restart network card found a network card does not flow, but the outside can ping the network card, and then a variety of Google, Baidu found that the original is eth2 in the local no default route, and then all the traffic has gone eth1. Workaround: New Add custom route table IP ro add default via [GW] dev eth2 table [1-252]Example:IP ro add default via
The route command in Linux is used to display and operate the IP route table (show/manipulatetheIProutingtable ). To achieve communication between two different subnets, you need a router that connects two networks or a gateway that is located in both networks.
In Linux, routing is usually set to solve the following problems: the Linux system has a gateway in a LAN that allows machines to access the Interne
When configuring Static Routing, you can specify both the sending interface and the next hop address. which method is used depends on the actual situation.

In the previous article, we used the description of the SIP Routing Mechanism to understand the definition and concept of the SIP routing mechanism. Next, let's explain these abstract concepts to help you understand them. Next, we will use two SIP routing instances to help you understand these concepts.

In the IGP era, we all know, for example, OSPF, link state protocol, in the routing of the time, than the cost of the link, which link consumption will be more priority, if two of the same link consumption, then do load balancing.
In fact, the 2 principles to achieve the OSPF---shortest path first work principle.
What if, in BGP, there are multiple routes to achieve the goal, how should the choice be made? Which path is the preferred one?
Take a look at the priority of these 11 attributes, an

The fact that r I p records only one route for each destination requires r I P to actively maintain the integrity of the route table. This is done by requiring all active r I p routers to broadcast the contents of their route tables to adjacent r I P routers at regular intervals, all received updates automatically replace the information already stored in the
XP multi-Nic static route setting methodOne, multiple IPs are in the same network segment or VALN. There's nothing to say about this, but you can set the IP address, subnet mask, and default gateway in the local connection properties of each NIC.Two, multiple IPs belong to different network segment or VLAN. At this point, if you set the IP address in the usual way, fill in the subnet mask and default gateway of each network segment, you will find that

Linux under route commandIn order for the device to access another subnet, you need to increase the routing to the sub-network in the device, here are some information. The basic operations are as follows:In general, to be able to access other subnets to set up the route, for example, your host is in 192.168.10.0/24, and you want to access the 192.168.20.0/24 network host, of course, you know a gateway IP,
