## Syntax

```
[no] ip router-advertise off|on
```

## Syntax Description

<table><thead><tr><th width="203">Keyword</th><th>Description</th></tr></thead><tbody><tr><td><code>no</code></td><td>(Optional) This is the same as <code>ip advertise off.</code></td></tr><tr><td><code>off</code></td><td>Disables the sending of IPv6 RA packets.</td></tr><tr><td><code>on</code></td><td>Enables the sending of IPv6 RA packets.</td></tr></tbody></table>

## Defaults

When autoconfiguration is enabled on an interface, the Island will determine the proper setting based on whether the the interface is determined to be a WAN or a LAN connection. Otherwise, the initial setting for newly-created interfaces is off.

## Usage Guidelines

This command determines whether IPv6 Router Advertisement (RA) packets are sent on an interface.

This command is valid only in interface context. Entering it will disable [autoconfig ](/island-router-cli-2.3.2/commands/ip-interface-context/ip-autoconfig.md)on the interface.

```
ip router-advertise on

## 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, and the optional `goal` query parameter:

```
GET https://docs.islandrouter.com/island-router-cli-2.3.2/commands/ip-interface-context/ip-router-advertise.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
