Use virtual routing and forwarding (VRF) to divide a J-EX Series switch into multiple
virtual routing instances. VRF allows you to isolate traffic traversing the network without
using multiple devices to segment your network. VRF is supported on all Layer 3 interfaces.
Before you begin, make sure to set up your VLANs. See "Configuring VLANs for J-EX Series
Switches (CLI Procedure)" on page 1136 or "Configuring VLANs for J-EX Series Switches
(J-Web Procedure)" on page 1133.
To configure virtual routing instances:
Create a routing instance:
1.
[edit routing-instances]
user@switch# set routing-instance-name instance-type virtual-router
NOTE: J-EX Series switches only support the virtual-router instance type.
Bind each routing instance to the corresponding physical interfaces:
2.
[edit routing-instances]
user@switch# set routing-instance-name interface interface-name.logical-unit-number
Create the logical interfaces that are bound to the routing instance.
3.
To create a logical interface with an IPv4 address:
[edit interfaces]
user@switch# set interface-name unit logical-unit-number family inet address ip-address
To create a logical interface with an IPv6 address:
[edit interfaces]
user@switch# set interface-name unit logical-unit-number family inet6 address
ipv6–address
NOTE: Do not create a logical interface using the
option in this step. Binding an interface using the
option to a routing instance can cause the interface to shutdown.
Enable VLAN tagging on each physical interface that was bound to the routing instance:
4.
[edit interfaces]
user@switch# set interface-name vlan-tagging
