160 Multiple Interfaces on Same Ethernet Broadcast Network
161 ------------------------------------------------------
162
163 Due to the default ARP behavior on Linux, it is not possible to have
164 one system on two IP networks in the same Ethernet broadcast domain
165 (non-partitioned switch) behave as expected. All Ethernet interfaces
166 will respond to IP traffic for any IP address assigned to the system.
167 This results in unbalanced receive traffic.
168
169 If you have multiple interfaces in a server, either turn on ARP
170 filtering by
171
172 (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
173 (this only works if your kernel's version is higher than 2.4.5), or
174
175 (2) installing the interfaces in separate broadcast domains (either
176 in different switches or in a switch partitioned to VLANs).
