Static extension configuration

Catalog

1. requirement ：

 2. Topological division ：

3. analysis ：

4. To configure ：

1. Configuration of loopback address , Direct interface IP Divide  

2. Static routing settings and r3 and r5 Floating between

 3. Spare configuration

4. Configure the necessary empty interface  

5. test

1. requirement ：

 2. Topological division ：

3. analysis ：

1. Divide reasonably according to the topological structure IP Address , Provide support for later manual summary , And avoid black holes
2. You need to write a default route , So as not to write directly 5.5.5.0/24 The route of can also be accessed
3. r4 and r5 The two lines between need to be configured with floating static

4. To configure ：

1. Configuration of loopback address , Direct interface IP Divide
