What is VRF in Nexus switch?

What is VRF in Nexus switch?

Nexus switches and newer versions of IOS support something called Virtual Routing and Forwarding (VRF) instances. Each VRF is a self-contained routing table within the same router. Within a Nexus 7000, you can have multiple VRFs within a single Virtual Device Context (VDC).

How do I check a VRF route?

Show VRF Information

1. To show the routes in a VRF, run the net show route vrf command. For example:
2. To show all VRFs learned by FRRouting from the kernel, run the show vrf command.
3. To list all VRFs, and include the VRF ID and table ID, run the ip -d link show type vrf command.

What is route leaking in VRF?

Inter-VRF local route leaking allows the leaking of routes from one VRF (the source VRF) to another VRF (the destination VRF) on the same router. Inter-VRF routes can exist in any VRF (including the default VRF) on the system.

How do I ping my VRF ip?

On the flipside, to perform ping test from the router to host on the LAN, use command ping vrf [VRF name] [target IP] so that the router knows which network that you are trying to reach. Notice that hosts on Company A and B can also have the same IP address. This because their network is completely separated.

What is ip route in VRF?

The “ip route ” command under the vrf context simply puts a route entry into the routing table and provides forwarding directions to packets leaving the management interface. It is not used to allow management traffic from the gateways.

Does Cisco NX-OS support route leaking between VRFs?

Cisco NX-OS supports route leaking (import or export) between VRFs. You can import IP prefixes from the global routing table (the default VRF) into any other VRF by using an import policy. The VRF import policy uses a route map to specify the prefixes to be imported into a VRF. The policy can import IPv4 and IPv6 unicast prefixes.

How do I import a VRF with a route-map?

The import vrf default command is configured in the destination VRF. The command line requires a route-map as a parameter in order to explicitly define the routes to be imported in the destination VRF which in this case is the VRF named BLUE. Step 3. Check the destination VRF Routing Table.

How many IP prefixes can be imported into a VRF?

By default, the maximum number of IP prefixes that can be imported from the default VRF into a non-default VRF is 1000 routes. There is no limit on the number of routes that can be leaked between two non-default VRFs. VRF route leaking requires an Enterprise license, and BGP must be enabled.
