RB1100Hx2: bridge or switch ?

Sat Jan 26, 2013 10:40 am


I have a RB1100Hx2.
- on Eth1 is my uplink
- on Eth2 is our server
- Eth3-10 is configured as bridge, connecting all our local devices

In an earlyer post I have been told, that the software bridge is less efficient
then using the hardware switching capabilities of the RB1100Hx2.

Can I group Eth3-10 in one switch?
Or better to use a dedicated switch?

I believe ports 1-5 are in one switch group and 6-10 are in another. To use ports 3-10, you could configure ports 3-5 to one switch group, ports 6-10 in another, then bridge those master ports together.

But then a dedicated switch is probably better...after all the RB1100AHx2 is a router :)

Try something like this:

# jan/26/2013 15:17:47 by RouterOS 6.0rc7

/ip address
add address= interface=ether1 network=
add address= interface=ether6 network=
add address= interface=Loopback_OSPF network=

/interface bridge
add name=Loopback_OSPF

/interface ethernet
set 0 arp=proxy-arp name=ether1 speed=1Gbps
set 1 master-port=ether1 name=ether2 speed=1Gbps
set 2 master-port=ether1 name=ether3 speed=1Gbps
set 3 master-port=ether1 name=ether4 speed=1Gbps
set 4 master-port=ether1 name=ether5 speed=1Gbps
set 5 name=ether6 speed=1Gbps
set 6 master-port=ether6 name=ether7 speed=1Gbps
set 7 master-port=ether6 name=ether8 speed=1Gbps
set 8 master-port=ether6 name=ether9 speed=1Gbps
set 9 master-port=ether6 name=ether10 speed=1Gbps
set 10 name=11_Public_11 speed=1Gbps
set 11 disabled=yes name=12_ether_12
set 12 disabled=yes name=13_ether_13

/ip pool
add name=pool_1 ranges=
add name=pool_2 ranges=

/ip dhcp-server
add add-arp=yes address-pool=pool_1 always-broadcast=yes disabled=no \
interface=ether1 lease-time=1d name=server1
add add-arp=yes address-pool=pool_2 always-broadcast=yes disabled=no \
interface=ether6 lease-time=1d name=server2

/routing ospf area
add area-id= name=area_1
/routing ospf instance
set [ find default=yes ] router-id=
/routing ospf network
add area=backbone network=

/ip dhcp-client
add default-route-distance=0 dhcp-options=hostname,clientid disabled=no \
interface=11_Public_11 use-peer-dns=no use-peer-ntp=no

/ip dhcp-server network
add address= gateway= netmask=25
add address= gateway= netmask=25

/ip dns
set allow-remote-requests=yes servers=,,

/ip firewall nat
add action=masquerade chain=srcnat \
src-address= !to-addresses !to-ports
add action=masquerade chain=srcnat src-address=\ !to-addresses !to-ports
add action=redirect chain=dstnat comment=" Redirect Proxy DNS" dst-port=53 \
protocol=tcp !to-addresses to-ports=53
add action=redirect chain=dstnat comment=" Redirect Proxy DNS" dst-port=53 \
protocol=udp !to-addresses to-ports=53

It works well for me, and you don't have to bridge as each switch group acts on its own (1-5) and (6-10)
