To enable IPv6 for BGP, enable IPv6 on global level using this guide and configure IPv4 BGP integration.
First of all, you need to enable BGP action for IPv6 traffic:
|
1 |
sudo fcli set main gobgp_ipv6 enable |
To announce attacked host (/128) use this option:
|
1 |
sudo fcli set main gobgp_announce_host_ipv6 enable |
And configure community numbers for host and subnet (it’s not implemented yet) blocks:
|
1 2 |
sudo fcli set main gobgp_community_host_ipv6 65001:666 sudo fcli set main gobgp_community_subnet_ipv6 65001:667 |
Finally, configure next hop to required value:
|
1 |
sudo fcli set main gobgp_next_hop_ipv6 100::1 |
Before moving this setup to production, try blocking any test host manually and check that all announces propagate correctly.
