https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278654 Bug ID: 278654 Summary: The -ifa modifier to route(8) is ineffective Product: Base System Version: 14.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: karels@freebsd.org In 14.0 and -current as of this bug report, the -ifa modifier to route(8) has no effect. For example, if 10.0.3.99 is an alias on vtnet0 or lo0, and a route is added via vtnet0 with -ifa 10.0.3.99, ping to that destination uses the primary address on vtnet0 as source. route get shows no indication of the ifa address. ping -S 10.0.3.99 works as expected. Details (this example from -current): vmguest1# ifconfig lo0 alias 10.0.3.99/32 vmguest1# netstat -rnf inet Routing tables Internet: Destination Gateway Flags Netif Expire default 10.0.3.254 UGS vtnet0 10.0.3.0/24 link#1 U vtnet0 10.0.3.1 link#2 UHS lo0 10.0.3.99 link#2 UH lo0 127.0.0.1 link#2 UH lo0 vmguest1# route add freebsd-test -ifa 10.0.3.99 -ifp 10.0.3.1 10.0.3.254 add host freebsd-test: gateway 10.0.3.254 vmguest1# route -n get freebsd-test route to: 10.0.2.21 destination: 10.0.2.21 gateway: 10.0.3.254 fib: 0 interface: vtnet0 flags: <UP,GATEWAY,HOST,DONE,STATIC> recvpipe sendpipe ssthresh rtt,msec mtu weight expire 0 0 0 0 1500 1 0 vmguest1# route delete freebsd-test delete host freebsd-test vmguest1# route add freebsd-test -ifa 10.0.3.99 -ifp 10.0.3.1 10.0.3.254 add host freebsd-test: gateway 10.0.3.254 vmguest1# route -nv get freebsd-test route to: 10.0.2.21 destination: 10.0.2.21 gateway: 10.0.3.254 fib: 0 interface: vtnet0 flags: <UP,GATEWAY,HOST,DONE,STATIC> recvpipe sendpipe ssthresh rtt,msec mtu weight expire 0 0 0 0 1500 1 0 ping 10.0.2.21 then uses a source address of 10.0.3.1. The result is the same if the alias is placed on vtnet0. -- You are receiving this mail because: You are the assignee for the bug.home | help
