Dell S3100 EMC Command Line Reference Guide for the Series 9.14.2.5 - Page 1583

Version 9.8(0.0P5) 9.8(0.0P2) 9.7(0.0) 9.4.(0.0) Description Introduced on the S4048-ON. Introduced on the S3048-ON. Introduced on the S6000-ON and Z9500. Introduced on the S-Series and Z9000. Usage Information You can attach an interface to either a nondefault VRF or a management VRF. To assign a port-back to a default VRF, remove the VRF association from the interface. You can use this only if there is no IP address configured on the interface. There must be no prior Layer 3 configuration on the interface when configuring VRF. You must enable VRF before using this command. You can configure an IP subnet or address on a physical or VLAN interface that overlaps the same IP subnet or address configured on another interface only if the interfaces are assigned to different VRFs. If you assign two interfaces to the same VRF, you cannot configure overlapping IP subnets or the same IP address to them. Example DellEMC# configure terminal DellEMC(conf)# ip vrf red DellEMC(conf-vrf)# description "Red Network" DellEMC(conf-vrf)# show config ! ip vrf red 4 description "Red Network" DellEMC(conf-vrf)# DellEMC(conf-if-gi-1/45)# int gi 1/46 DellEMC(conf-if-gi-1/46)# no shut DellEMC(conf-if-gi-1/46)# ip vrf forwarding red DellEMC(conf-if-gi-1/46)# ip add 100.1.1.1/24 DellEMC(conf-if-gi-1/46)# DellEMC(conf-if-gi-1/46)# DellEMC(conf-if-gi-1/46)# DellEMC(conf-if-gi-1/46)# show config ! interface GigabitEthernet 1/46 ip vrf forwarding red ip address 100.1.1.1/24 no shutdown DellEMC(conf-if-gi-1/46)# ip route-export Enables route leaking between VRFs. This command exports or shares IPv4 routes corresponding to one VRF with other nondefault VRFs. Syntax Parameters ip route-export tag [route-map-name] route-export tag route-map-name Enter the keywords route-export to leak or share routes between VRFs. Enter a tag (export route target) to expose routes to other VRFs. This tag acts as an identifier for exported routes. Use this identifier while importing these routes into another nondefault VRF. (Optional) Enter the name of the route-map to filter the exported routes. You can leak global routes to VRFs. As the global RTM usually contains a large pool of routes, when the destination VRF imports global routes, these routes are duplicated into the VRF's RTM. It is mandatory to use route-maps to filter out leaked routes while sharing global routes with VRFs. Command Modes • VRP mode • CONFIGURATION mode Virtual Routing and Forwarding (VRF) 1583
