OS for EX Series Ethernet Switches, Release 10.4
Use virtual routing and forwarding (VRF) to divide an 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 EX Series
Switches (CLI Procedure)" on page 1600 or "Configuring VLANs for EX Series Switches
(J-Web Procedure)" on page 1597.
To configure virtual routing instances:
Create a routing instance:
1.
[edit routing-instances]
user@switch# set routing-instance-name instance-type virtual-router
NOTE: 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
