netstat -r do not show bridge0 as the interface for default route.

[Monthadar Al Jaberi]

Hi,

I am still trying to learn how bridge(4) work internally. But I found
something that seems strange.

this is my rc.conf file:
defaultrouter=172.16.0.1
fsck_y_enable="YES"
inet_enable="YES"
sshd_enable="YES"
ntpdate_enable="YES"
ntpdate_hosts=172.16.0.1
rpcbind_enable="YES"
nfs_client_enable="YES"
rpc_lock_enable="YES"
rpc_statd_enable="YES"
sendmail_enable="NO"
cloned_interfaces="bridge0"
ifconfig_bridge0="inet 172.16.3.22 addm arge0"
ifconfig_arge0="up"



and when I type netstat -r it shows that the default route uses arge0
as the interface and not bridge0:

Shouldnt it be bridge0 because it has the ip address and it knows
which port a packet should go on?

For reference I am running current on an RSPRO using nfs mount.
