Example Step: Configuring Bridge Domains
There are two supported ways to configure an IRB with bridge domains. One way is to
use the
interface-mode trunk statement. The other way is shown here and is known as
the encapsulation method. The encapsulation method is the preferred way to configure
an IRB with bridge domains.
To configure the bridge domains on all three routers:
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;
}
}
2. Configure a bridge domain on Router 2:
[edit]
bridge-domains {
vlan100 {
domain-type bridge;
vlan-id 100;
