Configuring the Interfaces and VLAN Tags

Configure the Ethernet interfaces and VLAN tags on all three routers.

Note: The configurations in this chapter are only partial examples of complete and functional router configurations. Do not copy these configurations and use them directly on an actual system.

Router 1

On Router 1, configure the Ethernet interfaces and VLAN tags:

[edit chassis]
aggregated-devices {
ethernet {
device-count 2; # Number of AE interfaces on router
}
}
[edit]
interfaces ge-2/1/0 {
gigether-options {
802.3ad ae2;
}
}
interfaces ge-2/1/1 {
gigether-options {
802.3ad ae2;
}
}
interfaces ge-2/1/2 {
gigether-options {
802.3ad ae2;
}
}
interfaces ge-2/1/3 {
gigether-options {
802.3ad ae1;
}
}
interfaces ge-2/1/4 {
gigether-options {
802.3ad ae1;
}
}
interfaces ge-2/1/5 {
gigether-options {
802.3ad ae1;
}
}
interfaces ge-2/2/1 {
encapsulation flexible-ethernet-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 100 {
encapsulation vlan-bridge;
vlan-id 100;
}
unit 200 {
encapsulation vlan-bridge;
vlan-id 200;
}
}
interfaces ge-2/2/2 {
unit 0 {
family bridge {
interface-mode access;
vlan-id 205;
}
}
}
interfaces ge-2/2/4 {
native-vlan-id 200; # Untagged packets get vlan 200 tag
unit 0 {
family bridge {
interface-mode trunk;
vlan-id-list 200-205; # This trunk port is part of VLAN range 200–205
}
}
}
interfaces ge-2/2/6 {
encapsulation flexible-ethernet-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 200 {
encapsulation vlan-bridge;
vlan-id 200;
}
}
interfaces ae1 {
encapsulation extended-vlan-bridge;
vlan-tagging;
unit 100 {
vlan-id 100;
}
unit 200 {
vlan-id 200;
}
}
interfaces ae2 {
unit 0 {
family bridge {
interface-mode trunk;
vlan-id-list 100, 200–205;
}
}
}

Router 2

On Router 2, configure the Ethernet interfaces and VLAN tags:

[edit chassis]
aggregated-devices {
ethernet {
device-count 2; # Number of AE interfaces on the router
}
}
[edit]
interfaces ge-2/2/2 {
encapsulation flexible-ethernet-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 100 {
encapsulation vlan-bridge;
vlan-id 100;
}
}
interfaces ge-3/3/3 {
encapsulation flexible-ethernet-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 200 {
encapsulation vlan-bridge;
vlan-id 200;
}
}
interfaces ge-5/1/0 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-5/1/1 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-5/1/2 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-5/1/3 {
gigether-options {
802.3ad ae1;
}
}
interfaces ge-5/1/4 {
gigether-options {
802.3ad ae1;
}
}
interfaces ge-5/1/5 {
gigether-options {
802.3ad ae1;
}
}
interfaces ae1 {
encapsulation extended-vlan-bridge;
vlan-tagging;
unit 100 {
vlan-id 100;
}
unit 200 {
vlan-id 200;
}
}
interfaces ae3 {
encapsulation extended-vlan-bridge;
vlan-tagging;
unit 100 {
vlan-id 100;
}
unit 200 {
vlan-id 200;
}
}

Router 3

On Router 3, configure the Ethernet interfaces and VLAN tags:

[edit chassis]
aggregated-devices {
ethernet {
device-count 2; # Number of AE interfaces on router
}
}
[edit]
interfaces ge-2/2/2 {
encapsulation flexible-etherent-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 100 {
encapsulation vlan-bridge;
vlan-id 100;
}
}
interfaces ge-2/2/4 {
unit 0 {
family bridge {
interface-mode trunk;
vlan-id-list 200-205; # This trunk port is part of VLAN range 200–205
}
}
}
interfaces ge-2/2/6 {
unit 0 {
family bridge {
interface-mode acess;
vlan-id 200;
}
}
}
interfaces ge-3/3/3 {
encapsulation flexible-ethernet-services;
vlan-tagging; # Customer interface uses singly-tagged frames
unit 200 {
encapsulation vlan-bridge;
vlan-id 200;
}
}
[edit]
interfaces ge-11/1/0 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-11/1/1 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-11/1/2 {
gigether-options {
802.3ad ae3;
}
}
interfaces ge-11/1/3 {
gigether-options {
802.3ad ae2;
}
}
interfaces ge-11/1/4 {
gigether-options {
802.3ad ae2;
}
}
interfaces ge-11/1/5 {
gigether-options {
802.3ad ae2;
}
}
interfaces ae2 {
unit 0 {
family bridge {
interface-mode trunk;
vlan-id-list 100, 200–205;
}
}
}
interfaces ae3 {
encapsulation extended-vlan-bridge;
vlan-tagging;
unit 100 {
vlan-id 100;
}
unit 200 {
vlan-id 200;
}
}
