Bridge Interface Setup
interface bridge
Description
To bridge a number of networks into one bridge, a bridge interface should be created, that will
group all the bridged interfaces. One MAC address will be assigned to all the bridged interfaces.
Property Description
name (name; default: bridgeN) - a descriptive name of the interface
mtu (integer; default: 1500) - Maximum Transmission Unit
arp (disabled | enabled | proxy-arp | reply-only; default: enabled) - Address Resolution Protocol
setting
mac-address (read-only: MAC address) - Media Access Control address for the interface
forward-protocols (multiple choice: ip, arp, appletalk, ipx, ipv6, other; default: ip, arp, appletalk,
ipx, ipv6, other) - list of forwarded protocols
• other - all other protocols than AppleTalk, ARP, IP, IPv6, or IPX, e.g., NetBEUI, VLAN, etc.
priority (integer: 0..65535; default: 32768) - bridge interface priority. The priority argument is
used by Spanning Tree Protocol to determine, which port remains enabled if two (or even more)
ports form a loop
stp (no | yes; default: no) - whether to enable or disable the Spanning Tree Protocol
ageing-time (time; default: 5m) - how long the host information will be kept in the bridge database
forward-delay (time; default: 15s) - time which is spent in listening/learning state
garbage-collection-interval (time; default: 4s) - how often to drop old host entries in the bridge
database
Notes
forwarded-protocols is a simple filter that also affects the locally-destined and locally-originated
packets. So disabling ip protocol you will not be able to communicate with the router from the
bridged interfaces.
Example
To add and enable a bridge interface that will forward all the protocols:
[admin@Wandy] 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@Wandy] interface bridge> enable 0
