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 203.0.113.110/24; } } unit 1 { demux-source inet { family inet { address 203.0.113.111/24; } } } }
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 203.0.113.100/16; address 203.0.113.0/24; } } unit 101 { demux-options { underlying-interface ae0.1; } family inet { demux-source 203.0.113.221/16; address 203.0.113.0/24; } } } }
