Assigning an IP Address to the BROADway System

Creating a Bridge Virtual Interface (BVI)

Before you can add an interface to a bridge group, you should first create the bridge virtual interface (BVI) which attaches the bridge-group to the IP router. There is a one-to-one mapping between a BVI and a bridge-group; each BVI supports a single bridge-group. The BVI has an IP address which it utilizes to route its bridged traffic into the IP router and which can also be used to manage the BROADway system by performing the manage-intf enable command on the BVI.

You can enable and configure both Network Address Translation (NAT) and the DHCP relay agent on a BVI interface.

To create a BVI, use the following PS commands:

PS#configure

PS(NSP-config)#interface bvi <bvi number>

PS(NSP-config-bvi)#ip address <address> <mask>

<bvi number>—The number of the bridge virtual interface. You should use the same number that was configured for the bridge group.

<address>—The IP address of the interface. <mask>—The network mask for the interface.

NOTE: You must create a bridge group before creating the BVI.

For example, to create a bridge group, map the Ethernet interface to the bridge group, associate the bridge group with a BVI, assign an IP address to the BVI and enable the BVI IP address as a management interface for the system:

NSP1>ps

PS#configure

PS(NSP-config)#bridge addgroup 1

PS(NSP-config)#interface ethernet 0

PS(NSP-config-if)#bridge-group 1

PS(NSP-config-if)#exit

PS(NSP-config)#interface bvi 1

PS(NSP-config-bvi)#ip address 192.9.200.1 255.255.255.0 PS(NSP-config-bvi)#manage-intf enable

To delete a BVI use the following PS commands:

PS#configure

PS(NSP-config)#no interface bvi 1

To change the state of the BVI to “down”, use the following PS commands:

PS#configure

PS(NSP-config)#interface bvi 1

PS(NSP-config-bvi)#shutdown
