ros3.20(and v3.16) on x86 pc,the motherboard has 4 ethernet ports and 2 fiber ports,all ports are GB port.
ip address >add address=10.144.51.2/27 interface=lan1;
…
…
ip address >add address=10.144.51.30/27 interface=lan1;
the result pictue is
why does others(51.3-51.30) not active?
it has on route 10.144.51.0/27 with pref.source 10.144.51.2 in v2.9.51?
i asked someone,he said ,may be it(v3.20) has not supported the fiber port.
can you give an answer,and if not support really,what should i do ?
thanks!
why should they be active? they all point to the same destination and all have the same gateway interface, so the first is active, and others are invalid. maybe you’d like to add 10.144.51.2/32, 10.144.51.3/32, etc. addresses, not /27?
i try to add address with /32,it is active.
add 10.144.51.2/32 ,the route add DAC 10.144.51.2 pref.source 10.144.51.2
then add 51.3/32,the route add pref.source 51.3,and so on.i add 30 ip,it’s route give me 32 pref.source.
but new problem.
at some time,i add address with /27 on another ros(v3.20),it has only 4 enternet ports
add 51.2/27 …51.30/37 (total 30 ip),it give me only one record(DAC 10.144.51.0/27 pref.souce 10.144.51.2)
why?..
i am questioning the handware,may be really not supported!
thanks for answer!
it’s not hardware
today ,i tested v3.13 on vmwear,it works.
so,result is that,it is a bug.i also searched on google,other people have some problem too and v3.20 have many bugs.
wait for news after running v3.13 for some days.
thanks !
if 3.13 and 3.20 are buggy, use 3.23 
bad news,the nightmare continues,i have no idea.
hmmm… what does not work?..
i found the root causes of problem.
i did not plug the lines(my boss asked me to clone the configure of ros(v2.9.6),so i did not pulg the line,bad lucky!).
it is a special experience, 
it is a difference between v2.9.* and v3.*.
sorry,it happend angin.
i added address on the different interface,and the route add one DAC record.
after i reboot ros,the ip>route add DC with a pref.source of the ip.
can anybady do a test with v3.13 on vmware.
ros have 4 interfaces.
lan1 add address 10.144.51.2~14 (51.0/28)
lan2 add address 172.16.197.128/28 (130~144)
lan3 add address 192.168.0.0/26
lan4 add some other ip.
now look ip>route ,make sure it have 4 DAC.
then reboot the ros,login,and check ip>route have 4 DAC with 4 pref.source.
then tell me the result,with picture(best).
