Aggregated Ethernet Interfaces Feature Guide for Routing Devices
•
The following enhancements and additions apply to the “Example: Configuring
Multichassis Link Aggregation in an Active- Active Bridging Domain on MX Series
Routers” topic:
•
The Topology Diagram section fails to mention that interface ge-1/0/2 functions as
the ICCP link between the two PE devices, interface ge-1/1/1 is the ICL-PL link, and
interface ge-1/1/4 is the link that connects to the server or the MC- LAG client device.
•
As a best practice, we recommend that you configure the ICCP and ICL interfaces
over aggregated Ethernet interfaces instead of other interfaces such as Gigabit
Ethernet interfaces, depending on your topology requirements and framework.
•
You must disable RSTP on the ICL-PL interfaces for an MC-LAG in an active-active
bridging domain.
•
The Step-by-Step Procedure section for Router PE2 that is illustrated in the example
is missing, although the quick configuration statements are presented.
To configure Router PE2:
1.
Specify the number of aggregated Ethernet interfaces to be created.
[edit chassis]
user@PE2# set aggregated-devices ethernet device-count 5
2.
Specify the members to be included within the aggregated Ethernet bundles.
[edit interfaces]
user@PE2# set ge-1/0/5 gigether-options 802.3ad ae1
user@PE2# set ge-1/1/0 gigether-options 802.3ad ae0
3.
Configure the interfaces that connect to senders or receivers, the ICL interfaces,
and the ICCP interfaces.
[edit interfaces]
user@PE2# set ge-1/0/3 flexible-vlan-tagging
user@PE2# set ge-1/0/3 encapsulation flexible-ethernet-services
user@PE2# set ge-1/0/3 unit 0 encapsulation vlan-bridge
user@PE2# set ge-1/0/3 unit 0 vlan-id-range 100-110
user@PE2# set ge-1/0/4 flexible-vlan-tagging
user@PE2# set ge-1/0/4 encapsulation flexible-ethernet-services
user@PE2# set ge-1/0/4 unit 0 encapsulation vlan-bridge
user@PE2# set ge-1/0/4 unit 0 vlan-id-range 100-110
user@PE2# set ge-1/0/5 gigether-options 802.3ad ae0
user@PE2# set ge-1/1/0 gigether-options 802.3ad ae1
4.
Configure parameters on the aggregated Ethernet bundles.
