TH: That next-hop does look suspect. If they're on the same subnet, try disabling next-hop-self. It will just use link-local addressing on the foreign side, should the next hop be unreachable. It could be that with next-hop-self configured and no IPv6 address on lo, this isn't working correctly. Do you have a global address on lo? > Here's what my Quagga bgpd.conf looks like: > > hostname node4 > timers bgp 4 16 > > router bgp 54456 > bgp router-id 199.116.78.28 > redistribute connected metric 1 > redistribute static metric 1 TH: One thing you should add for sanity: no bgp default ipv4-unicast Otherwise Quagga will default to advertising IPv4 address family via IPv6 neighbors. 'bgp network import-check' is also useful to ensure Quagga behaves in the same way as a Cisco/Juniper router when it comes to advertisements (this goes for both address families). > neighbor 2607:1b00:10:a::1 remote-as 54456 > neighbor 2607:1b00:10:a::1 next-hop-self > > address-family ipv6 > network 2607:1b00:d1::/48 > network 2607:1b00:d2::/48 > neighbor 2607:1b00:10:a::1 activate > exit-address-family TH: This looks fine otherwise.
