Configuring Virtual Switches and Bridge Domains

Configure the virtual switches and bridge domains on all three routers. All bridge interfaces are members of the default virtual switch unless the bridge interface has been configured under an explicit virtual switch. In this example, all bridge interfaces and domains are not configured as part of an explicit virtual switch. Therefore, these bridge interfaces are automatically associated with the default virtual switch, and the trunk and access ports are automatically associated with the bridge domain in the default virtual switch based on VLAN membership.

Router 1

Configure a bridge domain on Router 1:



[edit]
bridge-domains {


vlan100 {
domain-type bridge;
vlan-id 100;
interface ge-2/2/1.100;
interface ae1.100;
}




vlan200 {
domain-type bridge;
vlan-id 200;
interface ge-2/2/1.200;
interface ge-2/2/6.200;
interface ae1.200;
}




vlan201 {
domain-type bridge;
vlan-id 201;
}




vlan202 {
domain-type bridge;
vlan-id 202;
}




vlan203 {
domain-type bridge;
vlan-id 203;
}




vlan204 {
domain-type bridge;
vlan-id 204;
}




vlan205 {
domain-type bridge;
vlan-id 205;
}


}

Router 2

Configure a bridge domain on Router 2:



[edit]
bridge-domains {


vlan100 {
domain-type bridge;
vlan-id 100;
interface ge-2/2/2.100;
interface ae1.100;
interface ae3.100;
}




vlan200 {
domain-type bridge;
vlan-id 200;
interface ge-3/3/3.200;
interface ae1.200;
interface ae3.200;
}


}

Router 3

Configure a broadcast domain on Router 3:



[edit]
bridge-domains {


vlan100 {
domain-type bridge;
vlan-id 100;
interface ge-2/2/2.100;
interface ae3.100;
}




vlan200 {
domain-type bridge;
vlan-id 200;
interface ge-3/3/3.200;
interface ae3.200;
}




vlan201 {
domain-type bridge;
vlan-id 201;
}




vlan202 {
domain-type bridge;
vlan-id 202;
}




vlan203 {
domain-type bridge;
vlan-id 203;
}




vlan204 {
domain-type bridge;
vlan-id 204;
}




vlan205 {
domain-type bridge;
vlan-id 205;
}


}
