then the packets will be encapsulated in a bridged-1483 format. If the configured
service is PPP, the packets will be encapsulated in BRCP.
To enable MAC-Encapsulated Routing in a VC profile, use the command:
set vc <vc_name> mac_routing enable
To disable the MAC-Encapsulated Routing in a VC profile, use th e command:
set vc <vc_name> mac_routing disable
Simultaneous Bridging and Routing
The OfficeConnect Remote 812 can be con figured for simultaneous bridging and
routing. IP routing is configured if IP forwarding is enabl ed (see Enabling IP
Routing). IPX routing is enabled if an IPX network is present over the Ethernet
interface (see Configuring IPX for the LAN). Bridging is e nabled by adding a bridge
network over the Ethernet interface. (see Configuring Bridging for the LAN).
Routing and bridging are enabled for each destina tion in its remote site profile.
When configured for simultaneous bridging and rou ting, packets received from
the LAN are first passed through the router for any configured protocols. If the
packet can not be routed it is passed to the bridge depending on the setting of t he
Bridge Firewall function.
The Bridge Firewall has three modes:
1Discard Routed Protocols:
This is the default mode. If a protocol is confi gured for routing and a packet for
that protocol type is received from the LAN that i s not addressed to the MAC
address of the OfficeConnect Remote 812, it is disc arded.Additionally, broadcasts
(including ARPs) for the protocol are not passed to the bridge. To configure the
Bridge Firewall for this mode, use the command:
set bridge firewall discard_routed_protocols
2Forward Unicast Packets Only:
If a protocol is configured for routing, and a packe t for that protocol type is
received from the LAN that is not addressed to the MAC address of the
OfficeConnect Remote 812, it is bridged. A dditionally, ARP broadcasts for IP
addresses other than that of the OfficeConnect Rem ote 812 are also bridged.
Other broadcasts for the configured protocol are not bridged. To configure the
Bridge Firewall for this mode, use the command:
set bridge firewall fwd_unicast_only
3Forward Broadcast/Unicast Packets:
Unicast packets for a configured protocol received from the LAN that are not
addressed to the MAC address of the OfficeConnect Remo te 812 are bridged.
Received broadcasts (e.g., DHCP) are bridged. To configure the Bridge Firewall for
this mode, use the command:
set bridge firewall fwd_bc_and_unicast
