Modern versions of Windows do not support OSPF and manually adding static routes every time after a reboot is annoying. Below is a batch script you can edit and run to help make adding routes easier. This script assumes that your BGP router and Windows computer are on the same LAN.

    @echo off
    REM fill in YOUR network information
    REM right click and RUN AS ADMIN

    REM our entire private network address space
    set networkv4=172.20.0.0
    set networkv4mask=255.252.0.0
    set networkv6=fd00::/8

    REM our IPv4 subnet info
    set subnetv4=172.20.184.240
    set subnetv4mask=255.255.255.248
    set gateway4=172.20.184.241

    REM our IPv6 subnet info
    set subnetv6=fd43:6d1:3ee2::/48
    set gateway6=fd43:6d1:3ee2:1000::1

    REM our address for this machine
    set yournetaddr=172.20.184.242
    set yournetaddr6=fd43:6d1:3ee2:1000::2/128

    REM add IPs
    REM if different change wlan0 to YOUR interface name
    REM first line here is for my LAN. Ignore it.
    netsh interface ipv4 add address "wlan0" 192.168.2.254 255.255.255.0
    netsh interface ipv4 add address "wlan0" %yournetaddr% %subnetv4mask%
    netsh interface ipv6 add address "wlan0" %yournetaddr6%

    REM add IPv4 routes
    route -4 add %subnetv4% mask %subnetv4mask% %gateway4%
    route -4 add %networkv4% mask %networkv4mask% %gateway4%

    REM add IPv6 routes
    route -6 add %gateway6% ::
    route -6 add %subnetv6% %gateway6%
    REM this last route wasn't working without manually filling in the info.
    REM I don't know why.. Broken line commented out.
    REM route -6 add %networkv6% %gateway6%
    route -6 add fd00::/8 fd43:6d1:3ee2:1000::1

    echo Press enter to check your IPv4 routing table
    echo Do not forget to add static routes to this computer on your BGP router!
    echo Example: "root@router:~# ip route add 172.20.184.242 dev wlan0"
    echo Example: "root@router:~# ip route add fd43:6d1:3ee2:1000::2/128 dev wlan0"
    pause
    cls
    route -4 print
    echo Press enter to check your IPv6 routing table
    pause
    cls
    route -6 print
    echo Press enter to try to ping gateway
    pause
    cls
    ping %gateway4%
    pause
    ping %gateway6%
    pause
