Example: Configuring a Static Subscriber Interface on an IP Demux Interface over Aggregated Ethernet
This example shows how you can configure a subscriber interface using a static IP demultiplexing (demux) interface stacked on a two-link aggregated Ethernet logical interface. In this example, the underlying aggregated Ethernet logical interface is configured for one-to-one active/backup redundancy at the DPC level.
- Define the number of aggregated Ethernet interfaces on
the router.
In this example, only one aggregated Ethernet logical interface is configured on the router:
[edit]chassis {aggregated-devices {ethernet {device-count 1;}}} - Configure ae0, a two-link aggregated Ethernet
logical interface to serve as the underlying interface for the static
IP demux subscriber interface.
In this example, the LAG bundle is configured for one-to-one active/backup link redundancy. To support link redundancy at the DPC level, the LAG bundle attaches ports from two different EQ DPCs.
[edit]interfaces {ge-5/0/3 {gigether-options {802.3ad {ae0;primary;}}}ge-5/1/2 {gigether-options {802.3ad {ae0;backup;}}}} - Configure the aggregated Ethernet logical interface with
link protection enabled, and specify the logical demultiplexing source
family type for both the active and backup links.[edit]interfaces {ae0 {aggregated-ether-options {link-protection;minimum-links 1;link-speed 1g;}unit 0 {demux-source inet {family inet {address 20.1.1.0/24;}}unit 1 {demux-source inet {family inet {address 20.1.1.1/24;}}}}
- Configure the IP demux interface over the aggregated Ethernet
logical interface.[edit]interfaces {demux0 {unit 101 {demux-options {underlying-interface ae0.0;}family inet {demux-source 10.1.0.0/16;address 1.1.1.0/24;}}unit 101 {demux-options {underlying-interface ae0.1;}family inet {demux-source 10.1.0.1/16;address 1.1.1.1/24;}}}}
