!chnroutes - chnroutes negated

nchnroutes

Similar to chnroutes, but instead generates routes that are not originating from Mainland China and generates result in BIRD static route format

Both IPv4 and IPv6 are supported.

As of Jul 2021, the size of generated table is roughly 11000-12000 entries for IPv4 (depends on the IP list used) and 14000 for IPv6. On a Raspberry Pi 4 with BIRD, full loading and convergence over OSPF with RouterOS running on Mikrotik hEX takes around 5 seconds.

For practical usage, check out my blog post (available in Chinese only): https://idndx.com/use-routeros-ospf-and-raspberry-pi-to-create-split-routing-for-different-ip-ranges/

Requires Python 3, no additional dependencies.

$ python3 produce.py -h

usage: produce.py [-h] [--exclude [CIDR [CIDR ...]]] [--next INTERFACE OR IP]
                  [--ipv4-list [{apnic,ipip} [{apnic,ipip} ...]]]

Generate non-China routes for BIRD.

optional arguments:
  -h, --help            show this help message and exit
  --exclude [CIDR [CIDR ...]]
                        IPv4 ranges to exclude in CIDR format
  --next INTERFACE OR IP
                        next hop for where non-China IP address, this is
                        usually the tunnel interface
  --ipv4-list [{apnic,ipip} [{apnic,ipip} ...]]
                        IPv4 lists to use when subtracting China based IP,
                        multiple lists can be used at the same time (default:
                        apnic ipip)

To specify China IPv4 list to use, use the --ipv4-list as the following:

• python3 produce.py --ipv4-list ipip - only use list from ipip.net
• python3 produce.py --ipv4-list apnic - only use list from APNIC
• python3 produce.py --ipv4-list apnic ipip - use both lists (default)

If you want to run this automatically, you can first edit Makefile and uncomment the BIRD reload code at the end, then:

sudo crontab -e

and add 0 0 * * 0 make -C /path/to/nchnroutes to the file.

This will re generate the table every Sunday at midnight and reload BIRD afterwards.

nchnroutes's Issues

参数问题

红线部分参数是否应该是bird4 -c configure

fatal: 不是一个 git 仓库（或者任何父目录）：.git

root@debian:~/ipv4# make
git pull
fatal: 不是一个 git 仓库（或者任何父目录）：.git
make: *** [Makefile:2：produce] 错误 128

请问--next怎么分别指定ipv4和ipv6地址呢？

由于某些原因，需要指定next为ip而不是接口，如何为v4和v6分别指定呢？谢谢。

ipaddress.AddressValueError

When I use Python3 to run produce.py,the following:
Traceback (most recent call last):
File "/root/nchnroutes/produce.py", line 121, in
a = IPv4Network(line)
File "/usr/lib/python3.9/ipaddress.py", line 1502, in init

ipaddress.AddressValueError: Only one '/' permitted in '<h1>Not Found</h1>The requested URL /17mon/china_ip_list/master/china_ip_list.txt was not found on this server.'
make: *** [Makefile:4: produce] Error 1

Does anyone help me?

奈飞

大佬，我发现用了rbc不能访问奈飞，显示Not Available，应该是直连的没走clash.meta，是routes4.conf和routes6.conf里面没有奈飞的ip吗

执行make报个错

缺失很多路由信息

生成的文件缺失很多路由信息，比如：172.217.0.0/16；2606:4700:20::/44 等等好多

请求更换IPv4数据源

感谢提供了全新的分流思路。apnic ipv4 国内段准确度感觉没有ipip（https://github.com/17mon/china_ip_list）的高，建议IPv4使用IPIP的源。
