I am running bird 2.0.7. Seeing issue with respect to ipv6 address add/delete on DR. This added/deleted ipv6 address prefix convergence is not happening till LSA refresh timer fires . Topology contains 3 routers connected to a switch. Say IPV6 addresses configured on Routers R1(1111::100/64), R2(2222:200/64),R3(3333::300/64). If we are deleting ipv6 addresses other than DR, I could see intra-area-prefix generated by DR and all routers converged with respect to add/deleted ipv6 addresses. With the below change, I could see intra-area-prefix LSA generated on DR also when ipv6 address added/deleted on DR. Please advise if this fix is correct ? --- a/bird-2.0.7/proto/ospf/iface.c +++ b/bird-2.0.7/proto/ospf/iface.c @@ -1187,6 +1187,8 @@ ospf_ifa_notify3(struct proto *P, uint flags, struct ifa *a) /* RFC 5340 4.4.3 Event 5 - prefix added/deleted */ ospf_notify_link_lsa(ifa); ospf_notify_rt_lsa(ifa->oa); + if(ifa->state == OSPF_IS_DR) + ospf_notify_net_lsa(ifa); } } Regards, Bala.
