# Настройка внутренней маршрутизации. OSPF

Собственно к этому и перейдём.

Наша задача, чтобы все знали обо всех линковых подсетях, адресах Loopback-интерфейсов и, естественно, о наших белых адресах.

Конфигурация OSPF:\
**R1**

```
router ospf 1
network 1.1.1.1 0.0.0.0 area 0
network 10.0.0.0 0.255.255.255 area 0
network 100.0.0.0 0.0.1.255 area 0
```

**R2**

```
router ospf 1
network 2.2.2.2 0.0.0.0 area 0
network 10.0.0.0 0.255.255.255 area 0
network 100.0.0.0 0.0.1.255 area 0
```

**R3**

```
router ospf 1
network 3.3.3.3 0.0.0.0 area 0
network 10.0.0.0 0.255.255.255 area 0
network 100.0.0.0 0.0.1.255 area 0
```

**R4**

```
router ospf 1
network 4.4.4.4 0.0.0.0 area 0
network 10.0.0.0 0.255.255.255 area 0
network 100.0.0.0 0.0.1.255 area 0
```

После этого появляется связность со всеми Loopback-адресами.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://linkmeup.gitbook.io/sdsm/8.1.-ibgp/1.-praktika/1.-nastroika-vnutrennei-mrshrutizacii-ospf.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
