Juniper Networks JUNOS OS 10.4 - Manual (Page 44)

• Router 1 has an access interface which provides bridging on VLAN 205 and is connected
to a customer device configured on
ge-2/2/2 . Router 3 has an access interface which
provides bridging on VLAN 200 and is connected to a customer device configured on
ge-2/2/6 .
• Router 1 and Router 3 are configured with a trunk interface to a switch for VLANs
200–205. On both routers, this interface is
ge-2/2/4 .
Example Configuration Summary
This procedure summarizes the minimum configuration steps required for Layer 2
processing in a bridged environment, as described in
“Layer 2 Features for a Bridging
Environment” on page 21 . The individual configuration steps are described in greater
detail in separate topics.
To configure Layer 2 processing in a bridged domain network:
1. Configure the Ethernet interfaces and VLAN tags on all three routers, as described in
“Example Step: Configuring Interfaces and VLAN Tags” on page 24
2. Configure the bridge domains on all three routers, as described in “Example Step:
Configuring Bridge Domains” on page 30 .
3. Configure the Spanning Tree Protocol on all three routers, as described in “Example
Step: Configuring Spanning Tree Protocols” on page 32
4. Configure IRB, as described in “Example Step: Configuring Integrated Bridging and
Routing” on page 34
