Multiple networks on same server
If I have 2 interfaces in a server on the same subnet/network does Solaris automatically choose to route packets destined for this network out the first interface. I.e if ce0 and ce1 were on same network ce0 would be chosen as it's first interface?

bprelay(8) System Manager's Manual bprelay(8)
NAME
bprelay - BOOTP relay agent
SYNOPSIS
/usr/sbin/bprelay [-f] [-d n] [-h hopcount] [-i interface,interface...] [-t minutes] [-w seconds] server...
OPTIONS
Foreground mode. In this mode, bprelay does not run as a daemon. All messages are written to stdout and stderr, although warnings and
errors are still sent to syslog(3). Without this option, bprelay listens on all interfaces on which the underlying protocol supports
broadcasting. With this option, bprelay listens only to those interfaces specified. Any non-existent or invalid interface name are
ignored. Sets debug level to the numeric value n. Larger values of n provides more debugging information. Instructs bprelay to not for-
ward packets if the value of the hops field in the BOOTP packet exceeds hopcount. Instructs bprelay to terminate if minutes have passed
without any packets being received. This option is only honored if bprelay was started from inetd(8). Instructs bprelay to not forward
packets until the secs field in the BOOTP packet header exceeds this value.
DESCRIPTION
The bprelay daemon forwards DHCP or BOOTP packets to the specified list of servers (server). Servers may be identified either by their IP
addresses or by their names. The bprelay agent normally runs as a daemon process, and may be started either from the shell command line
interface or by inetd(8).
The purpose of bprelay is to provide the same service as that found in router hardware, but to run on UNIX workstations. The bprelay agent
listens for DHCP/BOOTP packets on each of the interfaces specified in the command line, and relays each packet to the servers specified.
As a rule, bprelay forwards each and every packet to every server specified, but it omits servers whose IP address is found to be on the
same IP network as the receiving interface since those servers will presumably hear the original broadcast.
RESTRICTIONS
Non-standard subnet masks for all networks administered by bprelay, must be available either through /etc/netmasks or NIS.
