What is ubest/mbest? I guess it is unicast best and multicast best, but why nexus is showing both unicast and multicast in the "show ip route" ? Why there are many /32 routes marked as direct and local?. I was trying to implement inter-VRFs routing in a multi VRF-lite environment - there was a requirement to implement routing between two VRF domains on the same router. Inter-VSAN routing (IVR) over Fibre Channel and FCoE IVR Network Address Translation (NAT) over Fibre Channel. So now the network is different for both the customers. I need to configure the routing between VRFs. The VRF import policy uses a route map to specify the prefixes to be imported into a VRF. Cisco has lots of examples of inter-VRF route leaking in IOS, but I haven't been able to locate any examples of inter-VRF route leaking configuration in NX-OS. Underlay connectivity being direct or via an intermediate router does not have any bearing on the DCI. Cisco with the Nexus 7k range have VDCs (Virtual Device Contexts) and Juniper have logical-systems. InterVLAN routing allows communication between Virtual LANs. The Cisco NX-OS has two preconfigured instances of VPN Routing Forwarding (VRF) by default (management, default). VRF-lite route leaking Ruhann CCIE R&S , CCIE SP , MPLS September 13, 2010 April 12, 2012 4 Minutes The purpose of VRF-lite is to extend the logical separation of two different networks from a MPLS network down to a single CE router, connected to both these networks. In order to achieve end-to-end connectivity here, we will need to bounce into the global routing table before hoping to the far side VRF. Yesterday I completed the configuration of inter-VLAN routing (aka "router on a stick", or RoaS) as part of my ongoing CCNA preparation.

Inter-VRF Routing is an implementation of VRF-Lite in which route filtering is happening between different VRF's within a single box. This is one of those 'nice to know in case I ever need it' kind of topics for me. It is running re written version of NX-OS in ACI mode. 1 Can i say that all of the commands are for using management interface ? If so, i would be able to login to the Nexus through the management interface and make any configuration in the whole Nexus, right ?. If attaching external devices on a Layer 2 port running a routing protocol with the Nexus 7000's (e. In a VRF, of course. In order to separate the users from the servers, we are going to create a new VRF routing table on the core switch. 5851 (Routing and Switching/Storage Networking), Technical Marketing Engineer on Cisco's Nexus 7000 team, specializes in helping customers design end-to-end data center architectures. It provides a separate IP routing and forwarding table to each VPN and is used in concert with MP-iBGP (Multi-Protocol internal BGP) between provider equipment (PE) routers to provide Layer 3 MPLS-VPN. • Nexus hardware requirements and NX-OS licensing for MPLS and VRF. Cisco’s vendor-ID is 9, and the supported option has vendor-type 1, which is named “cisco-avpair. If you need to put shared services in a physically separate device, you are likely to use the third option. Specifically, my work LAN has some tunnels to other. Key take-away: NX-OS is pretty. You can configure a route policy to modify this behavior and set the VRF that Cisco NX-OS uses for incoming packets. However we are going going to completely forget about MPLS and look at what this does to a single IOS based router. I am using MP-BGP to extend VRFs between the two. Nexus have two VRF out of the box, "management" and "default". 0(3)I5(2), using 40G (QSFP-40G-SR-BD) links between the IPN devices and the spine switches and 10G links between the IPN devices using a breakout cable from the QSFP-40G-SR4 optic installed in the IPN devices. In my lab there is a hub router with one spoke. Ron Fuller, CCIE No. Virtual Internet Routing Lab Personal Edition (VIRL PE) is Cisco's powerful network virtualization and orchestration platform that enables the development of highly accurate models of existing or planned networks. R1#sh ip route vrf to-r2. x provide virtual routing and forwarding (VRF) support for select releases of the following operating systems: Cisco IOS 12. In this lab I’m going to create three VRF’s; one for each site. It is based on Wind River Linux and is inter-operable with other Cisco operating systems. The following section depicts the Cisco Nexus switches and Software versions deployed at the lab environment in order to configure and test the Routing over vPC feature. Specifically, my work LAN has some tunnels to other. The following is the connectivity of the switch The image …. In other words, VRF deployment without MPLS is known as VRF-Lite. For more details, read up on the Cisco website: Managing the Unicast RIB and FIB. Since each VRF is independent, the same IP subnet can exist in 2 different VRFs. Inter VRF-Lite or route leaking CCNP 2. 2(x) PDF - Complete Book (3. I guess VRF can accomplish this by having 2 routing tables. 10 in the Green VRF. The Cisco Catalyst 3550 series switches used here are layer 3 switches with built-in routing capabilities, making them the preferred choice at a reasonable cost.
