vrf definition <vrf-name> [force]

no vrf definition <vrf-name> [force]

Creates the VRF.

Syntax Description

vrf-name

VRF session name

force

"force" option was added on VRF creation command to bypass user confirmation for creating "mgmt" VRF

Default

N/A

Configuration Mode

config

History

3.4.2008

3.6.6000

Updated the notes section

3.9.2000

Added force option

Example

switch (config) # vrf definition my-vrf

switch (config vrf definition my-vrf) #

Related Commands

Notes

  • 63 VRFs are supported aside from the default VRF

  • In case of "mgmt" VRF creation, CLI will ask permission to save the current configuration (behave like "configuration write") and reload the system. If "force" option was passed, then no confirmation is needed.

    After reboot, mgmt VRF will be created with management interfaces in it. Also, clustered, mDNS, OpenFlow API and FTP/TELNET servers will run in managemtn VRF when started. All other services does not change their existing configuration.

    In case of management VRF removal, the CLI will ask permission to remove services that running in management VRF, save new configuration, and reboot the switch. If "force" option was passed, no confirmation is needed.

    After reboot, mgmt VRF will be removed and management interfaces will be moved to "default" VRF. Also, clusterd, mDNS, OpenFlow API, and FTP/TELNET servers will run in "default" VRF when started. Other services that were enabled in management VRF will be disabled, except ones that are enabled by default (i.e., "ntp", "snmp-server", "tacacs-server", "radius-server", "ldap", "web", and so forth)—they will be reset and enabled in "default" VRF. The logic of moving/shutting down services from removed VRF could be applied for ALL user-defined VRF`s.

Related Commands

Notes

rd [<ip addr>:<0-65,535> | <AS Number>:<0-4,294,967,295> | <AS Number>:<ip addr>]

IPv4 address

AS Number

Asynchronous machine number

Default

N/A

Configuration Mode

config vrf definition

History

3.4.2008

Example

switch (config vrf definition my-vrf) # rd 10.10.10.10:2

Related Commands

Notes

  • RDs internally identify routes belonging to a VRF to distinguish overlapping or duplicate IP address ranges. This allows the creation of distinct routes to the same IP address for different VPNs. The RD is a 64-bit number made up of an AS number or IPv4 address followed by a user-selected ID number. Once an RD has been assigned to a VRF it cannot be changed. To change the RD, remove the VRF then create it again. VRF is not active until an RD is defined.

  • An RD must be defined to enable IP routing on the VRF

vrf forwarding <vrf-name>
