Table 130. Creating a Non-Default VRF Instance
Task Command Syntax Command Mode
Create a non-default VRF instance by
specifying a name and VRF ID number,
and enter VRF configuration mode.
ip vrf vrf-name vrf-id VRF ID
range: 1 to 512 and 0 (default VRF)
CONFIGURATION
Assigning an Interface to a VRF
You must enter the ip vrf forwarding command before you configure the IP address or any other setting on an interface.
NOTE: You can configure an IP address or subnet on a physical or VLAN interface that overlaps the same IP address or
subnet configured on another interface only if the interfaces are assigned to different VRFs. If two interfaces are assigned
to the same VRF, you cannot configure overlapping IP subnets or the same IP address on them.
Table 131. Assigning an Interface to a VRF
Task Command Syntax Command Mode
