ip-prefix-support
Syntax
Hierarchy Level
Release Information
Statement introduced in Junos OS Release 15.1x53-D30.
Description
In an Ethernet VPN (EVPN) Virtual Extensible LAN (VXLAN) environment, enable the provider edge (PE) switch to forward the IP prefix associated with a specified customer domain in scenarios where the Layer 2 domain does not extend across data centers. Such routes are referred to as EVPN pure type-5 routes. On QFX switches, only fully resolved next-hop routes are supported. The data packets are sent as Layer 2 frames that are encapsulated in the VXLAN header. A unique VXLAN numerical identifier is associated with each customer domain.
When the advertisement of the type-5 route is enabled, you can
optionally use an export routing policy configured at the [edit
policy-options policy-statement policy-name] hierarchy level to further control the IP prefixes to advertise
or suppress through EVPN type-5 routes for each customer. The policy
is applied to the routes that reside in the customer’s inet.0
routing table by specifying a routing-instance-name configured at the [edit routing-instances] hierarchy
level. This routing-instance-name refers
to a Layer 3 virtual routing and forwarding (VRF) domain for a specific
customer. The corresponding name of the table is instance.name.inet.0
This table is created
by default when you configure a routing instance.
This statement is deprecated starting with Junos OS Release 15.1x53-D60 and has been replaced with ip-prefix-routes. The statement ip-prefix-support forwarding-mode symmetric is now ip-prefix-routes advertise direct-nexthop. Any configuration with the original ip-prefix-support statement is automatically upgraded to the new ip-prefix-routes statement when you upgrade to Junos OS Release 15.1x53-D60 or later.
Options
The forwarding-mode symmetric, encapsulation vxlan and vni number options are required. The export policy-name option is optional.
