Hi, I think you need to activate IPv6 neighbour in “address family ipv6 unicast” Ex. address-family ipv6 unicast neighbor xxxx:xxxx:xxxx:xxxx::x activate Thanks, Vijay From: frog <frog-bounces@lists.frrouting.org> On Behalf Of Andre Roberge Sent: 19 June 2019 19:56 To: frog@lists.frrouting.org Subject: [FROG] Configured AFI/SAFIs do not overlap Hi everyone, I am new to frr, sorry if this is not the right place for this question. I’m trying to peer with my providers in IPv4 and IPv6, the IPv4 part is working great but I get an error on IPv6. Any help would be greatly appriciated !
