https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266544 Bug ID: 266544 Summary: Cannot send to static ipv6 interface routes Product: Base System Version: 12.3-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jaunts_buys.0b@icloud.com Hello, Consider a static IPv6 deployment where there are multiple prefixes on the link. FreeBSD is configured with an ipv6 address on one of those prefixes, = but the other prefix must be reached via a static route. There are no router advertisements on the link. Problem: Traffic flows to the prefix for which the host has an address, but does not flow to the prefix via the static route. To Reproduce: 1) Install FreeBSD-12.3-RELEASE. I used the FreeBSD-12.3 VMDK VMware image = and logged in as root. 2) Configure the interface without specifying accept_rtad: # ifconfig em0 inet6 2001:db8:1::1/64 3) Observe ping6 2001:db8:1::1 works 4) Add static route to another prefix on the link: # route -6 add -net 2001:db8:2::/64 -iface em0 5) Observe pinging any host on 2001:db8:2::/64 does not work and produces t= he following error: ping6: sendmsg: No buffer space available ping6: wrote 2001:db8:2::2 16 chars, ret=3D-1 --=20 You are receiving this mail because: You are the assignee for the bug.=
