General Information

Always take care not to bridge virtual interfaces with their respective parent interfaces.
Example
To add and enable a bridge interface that will forward all the protocols:
[admin@MikroTik] interface bridge> add; print
Flags: X - disabled, R - running
0 X name="bridge1" mtu=1500 arp=enabled mac-address=00:00:00:00:00:00
forward-protocols=ip,arp,appletalk,ipx,ipv6,other stp=no priority=32768
ageing-time=5m forward-delay=15s garbage-collection-interval=4s
hello-time=2s max-message-age=20s
[admin@MikroTik] interface bridge> enable 0
Port Settings
Home menu level: /interface bridge port
Description
The submenu is used to group interfaces in a particular bridge interface.
Property Description
bridge (name; default: none) - the bridge interface the respective interface is grouped in
• none - the interface is not grouped in a bridge
interface (read-only: name) - interface name
path-cost (integer: 0..65535; default: 10) - path cost to the interface, used by STP to determine the
'best' path
priority (integer: 0..255; default: 128) - interface priority compared to other interfaces, which are
destined to the same network
Example
To group ether1 and ether2 in the bridge1 bridge:
[admin@MikroTik] interface bridge port> set ether1,ether2 bridge=bridge1
[admin@MikroTik] interface bridge port> print
# INTERFACE BRIDGE PRIORITY PATH-COST
0 ether1 bridge1 128 10
1 ether2 bridge1 128 10
2 wlan1 none 128 10
[admin@MikroTik] interface bridge port>
Bridge Monitoring
Command name: /interface bridge monitor
Description
Used to monitor the current status of a bridge.
