DES-7200 Configuration Guide Chapter 8 VRF
Configuration
8-3
Command Function
DES-7200(config)# no ip vrf vrf-name
Remove VRF.
8.3.2 Enabling VRF on the Interface
Command Function
DES-7200(config-if)# ip vrf
forwarding vrf-name
If you don't need to enable IPv6 on the
interface, you can associate the interface to
single-protocol IPv4 VRF. If you need to
enable IPv6 on the interface, you are not
suggested to use this command to associate
the interface with single-protocol IPv4 VRF.
DES-7200(config-if)# no ip vrf
forwarding vrf-name
Remove the interface from single-protocol
IPv4 VRF.
By default, the interface doesn't belong to any VRF; it belongs to the global
routing table.
Caution
（1） After associating the interface with the single-protocol VRF supporting
IPv4 only, the IPv4 address configured on the original interface will be removed,
and the IPv6 address configured on the interface won't be compromised.
（2） On layer-3 switch supporting VRF, if you associate the interface with
single-protocol IPv4 VRF and enable IPv6 protocol on this interface at the same
time, the switch won't be able to forward the IPv6 packets received on the
interface.
8.3.3 Configuring Routing Protocol
Command Function
DES-7200(config)# ip route vrf
vrf-name network mask interface
nexthop
Add the static route.
DES-7200(config-if)# no ip route vrf
vrf-name network mask
Delete the static route.
The routing protocol can also be used.
