I just compiled OpenWrt (attitude_adjustment) without firewall
When enter ifconfig no br-lan appear, moreover eth1 static ip doesn't show :
root@OpenWrt:/# ifconfig

My /etc/config/network config :
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config interface 'lan'
option ifname 'eth1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
config interface 'wan'
option ifname 'eth0'
option proto 'dhcp'
I don't know where to search for. Perhaps bad menuconfig when building?

You can think of eth1 as one physical interface on you router which is connected (hardwired to the switch), which includes all your Ethernet LAN ports (4 in most home routers).
Now br-lan is logical interface between eth1 and that switch. It is configured by default in OpenWRT (which oddly isn't in your case). You can create this virtual interface manually by LuCI or CLI. Here is the guide to do it in CLI: Or you can use LuCI which is simpler. Select interface as bridge and select eth0 (your WAN port) and eth1.
