Explains how to configure a VLAN bundle, detailing necessary configuration steps and guidelines to ensure successful deployment within Layer 2 VPN environments.
Creating a VLAN bundle enables efficient use of multiple links and organizes traffic by VLAN. The procedure is similar to creating VLAN sub-interfaces on a physical Ethernet interface.
Before you begin
To configure VLAN bundles, complete these configurations:
-
Create a bundle instance.
-
Create a VLAN interface (bundle sub-interface).
-
Map the physical interface(s) to the bundle.
-
Ensure that the same configuration is performed on both endpoints of the VLAN bundle.
Procedure
|
1. |
Create the VLAN bundle.
Example:
Router# configure
Router(config)# interface Bundle-Ether 2
Router(config-if)# ipv4 address 50.0.0.1/24
Router(config-if)# bundle maximum-active links 32 hot-standby
Router(config-if)# bundle minimum-active bandwidth 30000000
Router(config-if)# bundle minimum-active links 1
Router(config-if)# commit
Router(config-if)# exit
|
|
2. |
Create the VLAN sub-interface and add it to the bundle.
Example:
Router(config)# interface Bundle-Ether 2.201
Router(config-subif)# ipv4 address 12.22.1.1 255.255.255.0
Router(config-subif)# encapsulation dot1q 201
Router(config-subif)# commit
Router(config-if)# exit
|
|
3. |
Map the physical interface to the bundle.
Example:
Router(config)# interface HundredGigE 0/0/0/14
Router(config-if)# bundle id 2 mode on
Router(config-if)# no shutdown
Router(config-if)# commit
Router(config-if)# exit
Repeat the same mapping for member interfaces 0/0/0/15, 0/0/0/16, and 0/0/0/17 in this example.

4. |
Check the running configuration.
Example:
Router# show running-configuration
configure
interface Bundle-Ether2
ipv4 address 50.0.0.1 255.255.255.0
mac-address 1212.1212.1212
bundle maximum-active links 32 hot-standby
bundle minimum-active links 1
bundle minimum-active bandwidth 30000000
!
interface Bundle-Ether2.201
ipv4 address 12.22.1.1 255.255.255.0
encapsulation dot1q 201
!
interface HundredGigE0/0/0/14
bundle id 2 mode on
!
interface HundredGigE0/0/0/15
bundle id 2 mode on
!
interface HundredGigE0/0/0/16
bundle id 2 mode on
!
interface HundredGigE0/0/0/17
bundle id 2 mode on
!

5. |
Use the show interfaces bundle-ether 2.201 command to verify that the VLAN status is UP.
Example:
Router# show interfaces bundle-ether 2.201
Bundle-Ether2.201 is up, line protocol is up
Interface state transitions: 1

Internet address is 12.22.1.1/24

reliability 255/255, txload 0/255, rxload 0/255
Encapsulation 802.1Q Virtual LAN, VLAN Id 201, loopback not set,
Last link flapped 07:45:25
