# Auto-DHCP-Option
A script to auto set Main Router's dhcp_option.
## Introduction
Our network topology:
`3` means Gateway's IP and `6` means DNS Server's IP.
But there is an problem: **If our Side Router down, we can't connect to Internet.**
So, this script will check Side Router status, if it is down, remove `dhcp_option`.
If Side Router is down, we can manually reconnect devices to Main Router, and use Internet normally.
## Usage
### Install
Run below command in **Main Router**.
```shell
wget https://raw.githubusercontent.com/WingLim/dotfiles/Auto-DHCP-Option/ado_init.sh
sh ado_init.sh init your_side_router_ip
```
Script will creat a dir name `auto_dhcp_option` and generate `check_status.sh` in it.
Add a cron to execu `check_status.sh` every 10 mins.
### Remove
```shell
sh ado_init.sh remove
```
