Nexus 7000 vrf lite leakage

[vciric]

Hello,

We are installing Nexus 7K as a data center switch. It is necessary to have VRF lite configured to separate routing tables between some VLANs. There need to be some visibility between some VRFs and global routing table. Is it possible to import route from global routing table in VRFs, like on any other L3 switch with following configuration:

interface Vlan310
ip vrf select source
ip vrf receive V2
ip vrf receive V3

Is it also possible to have route leakage between VRFs (route target export and import)?

Hi,

This is currently not supported in NXOS and you need to use route-maps to update the next hop.

You need to run MPLS/LDP to achieve such a thing with RT Import/Export. Keep in mind that Route Targets are BGP extended communities.
