1342 OSPF and OSPFv3
Configuring OSPF VRFs
Dell EMC Networking VRF is an implementation of Virtual Routing and
Forwarding (VRF) for OSPF for IPv4 networks. Virtual Routing and
Forwarding allows multiple independent instances for the forwarding plane to
exist simultaneously. Refer to "VRF" on page 1345 for more information.
VRF configuration follows the same steps as configuration for the default
routing instance with two additional steps: creating the VRF instance and
associating VLANs to the instance. Existing commands which 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.
Follow the steps below to create a VRF and enable OSPF routing in the VRF:
First, 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.
In global config mode, create the pool of VLANs:
console#configure terminal
console(config)#vlan 100-109
console(config-vlan100-109)#exit
Assign the VLAN to an interface:
console(config)#interface gi1/0/1
console(config-if-Gi1/0/1)#switchport access vlan 100
console(config-if-Gi1/0/1)#exit
Create the VRF and enable routing:
console(config)#ip vrf red
console(config-vrf-red)#ip routing
console(config-vrf-red)#exit
Assign IP addresses to the interfaces:
console(config)#interface vlan 100
