Router Settings for static routes, the difference between default routes and static routes

Didn't understand what you said above. Teach you a simple way. When sending packets from R0 to R4, you can flush all from R0 to R3 with a default route.

This one is more convenient. On the backhaul route, make an interconnection IP segment of R0 and R1, R1 and R2, and R2 and R3 on R4 as the target address. The address of the next hop refers to the address of the interface on R3 to which R4 is connected to R3.

R3 uses only the interconnection IP segments of R0 and R1 and R1 and R2 as the target address. The address of the next hop refers to the address of the interface on R2 that R2 is associated with R3. That should make it through.

If you want r0 to ping r4, you need to do so many static routes:

Make a route on R0 that points to R4 (the next hop is R1).

Make a route on R1 that points to R4 (the next hop is R2).

Make a route on R2 that points to R4 (with the next hop being R3).

Then the reverse route has to be written again:

Make a route on r4 that points to r0 (the next hop is r3).

Make a route on R3 that points to R0 (the next hop is R2).

Make a route on r2 that points to r0 (the next hop is r1).

There is no protocol, no static route, and none of them are in the same broadcast domain. The simplest direct start to OSPF. Static routes are fools' errands. Exhaustion counts.

ro ping r4 r0 has three destination addresses, and the static route must be marked with the IP address of the destination network in addition to direct connection.

Just look at the routing table to see if it's aware of all the networks.

First, the reference is different.

2. Static routing: A routing method, the routing entry is manually configured, rather than dynamically determined.

Second, the way is different.

1. Default route: All packets whose destination is not in the router's routing table will use the default route. This route connects to another router, which also processes packets.

2. Static routes: Static routes are fixed and will not change, even if the network conditions have changed or been reconfigured. Static routes are added to the routing table by the network administrator one by one.

Third, the advantages are different.

1. Default route: When a router that knows how to reach the destination address is reached, the router will select a valid route based on the longest orange prefix matching. The subnet mask matches the destination IP address and the longest network is selected.

2. Static routing: The network can also use static routing for security considerations. It does not consume network bandwidth because static routes do not generate update traffic.

A static route is a fixed route entry that is manually set in the router. So how to set up a static router? Here's my answer, I hope it can help you!

ICMP redirect is the process in which a router sends an ICMP redirect packet to a host to request the host to change the route and send packets from the host to the corresponding destination. Let's take an example.

Typical Applications:

In a corporate network, not only can you connect to the external network through wireless router B, but you can also connect to the company's intranet server through wireless router A. Without modifying the IP address and gateway of the local connection, the company computer needs to be able to access both the public and intranet servers. The following figure shows the configuration example

By default, the PC will not be on the same network segment as itself. The data is sent to the gateway, which is the wireless router B. Once Router B receives the data, it checks the destination address of the packet.

If a packet with the destination IP address is found, the router will send an ICMP redirect packet to the PC to inform the PC that all subsequent packets sent to the network segment can be sent to Router A. This allows the PC to directly access the company's intranet server. The detailed configuration process in our TL-WR541G+ wireless router is as follows:

Step 1:

Step 2:

Click Add New Entry and set the parameters in the static route table.

Step 3:

After you click Save, you can view the existing configurations in the static route table.

Step 4:

Access the intranet server on the PC to check whether the static route entries take effect. If it can be accessed, the static route configuration is successful.
