Creating a Non-Default VRF Instance
VRF is enabled by default on the switch and supports up to 64 VRF instances: 1 to 63 and the default VRF (0).
• Create a non-default VRF instance by specifying a name and VRF ID number, and enter VRF conguration mode.
CONFIGURATION
ip vrf vrf-name vrf-id
The VRF ID range is from 1 to 63. 0 is the default VRF ID.
Assigning an Interface to a VRF
You must enter the ip vrf forwarding command before you congure the IP address or any other setting on an interface.
NOTE: You can congure an IP address or subnet on a physical or VLAN interface that overlaps the same IP address or subnet
congured on another interface only if the interfaces are assigned to dierent VRFs. If two interfaces are assigned to the same
VRF, you cannot congure overlapping IP subnets or the same IP address on them.
• Assign an interface to a VRF instance.
INTERFACE
ip vrf forwarding vrf-name
Assigning a Front-end Port to a Management VRF
Starting in 9.7(0.0) release, you can assign a front-end port to a management VRF and make the port to act as a host interface.
NOTE
: You cannot assign loop-back and port-channel interfaces to a management port.
To assign a front-end port to a management VRF, perform the following steps:
1 Enter the front-end interface that you want to assign to a management interface.
CONFIGURATION
interface gigabitethernet 1/1
2 Assign the interface to management VRF.
INTERFACE CONFIGURATION
ip vrf forwarding management
Before assigning a front-end port to a management VRF, ensure that no IP address is congured on the interface.
3 Assign an IPv4 address to the interface.
INTERFACE CONFIGURATION
ip address 10.1.1.1/24
Before assigning a front-end port to a management VRF, ensure that no IP address is congured on the interface.
4 Assign an IPv6 address to the interface.
INTERFACE CONFIGURATION
ipv6 address 1::1
You can also auto congure an IPv6 address using the ipv6 address autoconfig command.
