Hi
I am try to do following thing - configure another interface with same
address on same broadcast segment (but wired) and then change route
entry from one interface to another:
# ifconfig iwi0
iwi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.111 netmask 0xfffffe00 broadcast 192.168.1.255
ether 00:0e:35:03:82:74
media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)
status: associated
...
# netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.1.1 UGS 0 511183 iwi0
127.0.0.1 127.0.0.1 UH 1 626 lo0
192.168.0/23 link#3 UC 0 0 iwi0
192.168.1.111 127.0.0.1 UGHS 0 0 lo0
192.168.1.255 ff:ff:ff:ff:ff:ff UHLWb 0 1 iwi0
#
All is ok so far, then configure same address on another interface (not wireless):
# ifconfig fxp0 192.168.1.111/23
# ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet 192.168.1.111 netmask 0xfffffe00 broadcast 192.168.1.255
ether 08:00:46:c8:45:b3
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
Ok, routing not changed, now I whant to change route entry 192.168.0/23 -> iwi0, to 192.168.0/23 -> fxp0
# route change 192.168.0/23 -iface fxp0 -cloning
change net 192.168.0: gateway fxp0
#
looks like ok, but:
# netstat -rn

192.168.1.111 127.0.0.1 UGHS 0 0 lo0
#
nothing changed, delete + add works as expected:
# route delete 192.168.0/23 && route add 192.168.0/23 -iface fxp0 -cloning
delete net 192.168.0
add net 192.168.0: gateway fxp0
# netstat -rn

192.168.1.111 127.0.0.1 UGHS 0 0 lo0

(default still goes through wireless, as expected)
Any ideas what wrong with 'route change' ?
