Dell EMC Networking VRF is an implementation of Virtual Routing and
Forwarding (VRF). Virtual Routing and Forwarding allows multiple
independent instances for the forwarding plane to exist simultaneously. This
allows the administrator to segment the network without incurring the costs
of multiple routers. Each VRF operates as an independent VPN. The IP
addresses assigned to each VPN may overlap. Static route leaking to and from
the global instance is supported. VRF associated VLANs may not overlap with
other VRF instances.
The following capabilities are supported for Dell EMC Networking VRFs:
• Static routing (including route leaking)
• OSPF (IPv4 only)
• ARP
• Ping
• VRRP
• Trace route
• DHCP relay (IP helper)
• ICMP echo reply configuration
• ICMP error interval configuration
VRF configuration follows the same configuration steps as the default routing
instance with two additional steps: creating the VRF instance and associating
VLANs to the instance. Existing commands that have been enabled for VRF
accept an additional VRF instance identifier (name). VRF names can be up
to 32 characters in length. If a VRF instance identifier is not used in the
command, it applies to the global routing instance by default.
To create a VRF and enable OSPF routing in the VRF:
1 Create the VLAN instances associated to the VRF. It is recommended that
a VLAN numbering scheme be developed to allow for future growth and to
assist in the easy recognition of which VLANs are associated to which
VRFs.
2 In global config mode, create the pool of VLANs.
