Virtual routing and forwarding (VRF) enables partitioning of a physical router into multiple virtual routers. The control and data plane are isolated in each virtual router (VR) so that traffic does not flow across VRs. VRF allows multiple instances of routing tables to co-exist within the same router simultaneously. SmartFabric OS10 supports a management VRF instance and a default VRF instance.
All front panel ports and logical interfaces are part of the default VRF instance. Management ports may be added to the management VRF instance.
Use the serial console port to perform the steps in the example below. These instructions will remove the IP address, configure the management VRF, and then add the IP address back to the management interface.
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# show configuration
!
interface mgmt1/1/1
no shutdown
ip address 10.16.208.125/16
ipv6 address autoconfig
OS10(conf-if-ma-1/1/1)# no ip address
OS10(conf-if-ma-1/1/1)# no ipv6 address autoconfig
OS10(conf-if-ma-1/1/1)# exit
OS10(config)# ip vrf management
OS10(conf-vrf)# interface management
OS10(conf-vrf)# exit
OS10(config)# interface mgmt1/1/1
OS10(conf-if-ma-1/1/1)# no shutdown
OS10(conf-if-ma-1/1/1)# ip address 10.16.208.125/16
OS10(conf-if-ma-1/1/1)# ipv6 address autoconfig
