31.15 IP Bridge Commands

These sections explain how to set up the IP bridge function in the system.
The IP bridge function is designed for large-scale, flat, access networks, and it is ideal when
the network is based on Ethernet. When the IP bridge is enabled, the system forwards frames
based on the destination IP address, instead of the destination MAC address, and it replaces
the source MAC address with its own MAC address.
You can follow these steps to set up a simple IP bridge.
1 Create a domain. (Each domain is an ISP.)
2 Create one or more VLANs in the domain. (For example, one VLAN is for high-speed
Internet, and another VLAN is for VoIP.)
3 Specify one or more edge routers for the domain.
4 Create routing table entries, so the system forwards frames to the appropriate edge
router.
5 Create downlink interfaces, so the system forwards frames to the appropriate
subscribers.
6 Create PVCs for the subscribers.

31.16 IP Bridge ARP Proxy Commands

Use these commands to look at and flush the Address Resolution Protocol (ARP) table for
each domain. You can also configure how long the system keeps entries in the ARP table.
The system is an ARP proxy for edge routers and subscribers in an IP bridge. You can
configure basic settings for this, and you can look at (and flush, in some cases) the (PVC,
MAC, IP, VID) information the system has learned using DHCP snooping and ARP.

31.16.1 port ipbpvc arpproxy age Command

Syntax:
port ipbpvc arpproxy age <sec>
where
<sec>
This command configures how long the device stores the IP addresses of CPE devices in IP
bridges in the Address Resolution Protocol table.

31.16.2 port ipbpvc arpproxy flush Command

Syntax:
port ipbpvc arpproxy flush <all | edgerouter [<ip-address> <vid>] | interface
[<ip/mask> <vid>]>
where
all
718
The number of seconds (10~10000) the device is to keep the Address
=
Resolution Protocol table's entries of IP addresses in IP bridges.
All ARP table entries.
