https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236833 --- Comment #4 from Grzes <grzesiek@bajtnetbusko.pl> --- RADIX_MPATH I use to route to two default gateways to the edge router. I ha= ve two links leased from different providers and balances outgoing and incoming traffic, in case of problems with one whole traffic goes the other thanks to ospfd with frr5.0 which supports multipath routing. I get on bandwidth and I have a backup provider failure. Router is FreeBSD 11.2 with RADIX_MPATH, os= pfd with frr5. Each provider on a different network infrastructure. ifconfig ng0: flags=3D88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 = mtu 1492 inet 192.168.249.1 --> 192.1.1.2 netmask 0xffffffff nd6 options=3D9<PERFORMNUD,IFDISABLED> groups: tun ng1: flags=3D88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 = mtu 1480 inet 192.168.249.1 --> 192.1.1.3 netmask 0xffffffff nd6 options=3D1<PERFORMNUD> groups: tun netstat -rn 192.168.249.1 link#9 UHS lo0 192.1.1.3 link#10 UH ng1 x.x.x.x/28 link#5 U em0 x.x.x.x link#5 UHS lo0 192.1.1.2 link#9 UH ng0 After disconnecting all pppoe sessions and reconnecting with the error "ifa_maintain_loopback_route: deletion failed for interface ng1: 3" the rou= ting table has a doubled entry netstat -rn 192.168.249.1 link#9 UHS lo0 192.168.249.1 link#9 UHS lo0 192.1.1.3 link#10 UH ng1 192.1.1.2 link#9 UH ng0 ifconfig ng0: flags=3D88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 = mtu 1492 inet 192.168.249.1 --> 192.1.1.2 netmask 0xffffffff nd6 options=3D1<PERFORMNUD> groups: tun ng1: flags=3D88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 = mtu 1492 inet 192.168.249.1 --> 192.1.1.3 netmask 0xffffffff nd6 options=3D1<PERFORMNUD> groups: tun Log from the production machine: Mar 29 17:51:22 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng239: 3 Mar 29 17:58:55 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng270: 3 Mar 29 18:05:14 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng236: 3 Mar 29 18:06:45 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng236: 3 Mar 29 18:07:38 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng220: 3 Mar 29 18:07:51 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng5: 3 Mar 29 18:29:26 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng279: 3 Mar 29 18:32:25 xxxxx kernel: ifa_maintain_loopback_route: switch failed for interface ng1: 3 --=20 You are receiving this mail because: You are the assignee for the bug.=
