epair0a routes to lo0?

[Anh Ky Huynh]

Hi all,

I created epair devices by using ifconfig

$ ifconfig epair1 create
$ ifconfig epair1a inet 10.0.4.3 netmask 0xffffff00 broadcast 10.0.4.255
$ ifconfig epair1a inet 10.0.4.1 netmask 0xffffff00 broadcast 10.0.4.255 alias

Thing makes me confused is that the routing table

$ netstat -rantfinet
Destination        Gateway            Flags    Refs      Use  Netif Expire
default            192.168.0.1        UGS         0        0    em0
10.0.4.0/24        link#6             U           0        0 epair1
10.0.4.1           link#6             UHS         0        0    lo0
10.0.4.3           link#6             UHS         0        0    lo0
127.0.0.1          link#5             UH          0        0    lo0

Why are 10.0.4.1 and 10.0.4.3 routed to lo0? (I expected that it would be em0).

Thank you for your replies,

Regards,
