hello all,
I’m implementing an enviroment with BGP + Ipv6 but I m having a trouble with the routes that I receive from ISP. I received the correct route default , but the vyos send the packets to fe80 address… and this address fe80 is the link local address from ISP too. i dont know how to fix it…
vyos@vyos:~$ show ipv6 bgp
