Example Step: Configuring 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.

1. Configure the Ethernet interfaces and VLAN tags on Router 1:

   [edit]

   chassis {aggregated-devices {ethernet {device-count 2; # Number of AE interfaces on router}}}

   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 framesunit 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 tagunit 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 framesunit 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;}}}

2. Configure the Ethernet interfaces and VLAN tags on Router 2:

   [edit]

   chassis {aggregated-devices {ethernet {device-count 2; # Number of AE interfaces on the router}}}

   interfaces ge-2/2/2 {encapsulation flexible-ethernet-services;vlan-tagging; # Customer interface uses singly-tagged framesunit 100 {encapsulation vlan-bridge;vlan-id 100;}}

   interfaces ge-3/3/3 {encapsulation flexible-ethernet-services;vlan-tagging; # Customer interface uses singly-tagged framesunit 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;}}

3. Configure the Ethernet interfaces and VLAN tags on Router 3:

   [edit]

   chassis {aggregated-devices {ethernet {device-count 2; # Number of AE interfaces on router}}}

   interfaces ge-2/2/2 {encapsulation flexible-ethernet-services;vlan-tagging; # Customer interface uses singly-tagged framesunit 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 access;vlan-id 200;}}}

   interfaces ge-3/3/3 {encapsulation flexible-ethernet-services;vlan-tagging; # Customer interface uses singly-tagged framesunit 200 {encapsulation vlan-bridge;vlan-id 200;}}

   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;}}
