  • Page 4: Configuring Evi

    Configuring EVI Overview Ethernet Virtual Interconnect (EVI) is a MAC-in-IP technology that provides Layer 2 connectivity between distant Layer 2 network sites across an IP routed network. It is used for connecting geographically dispersed sites of a virtualized large-scale data center that requires Layer 2 adjacency (see Figure EVI enables long-distance virtual machine workload mobility and data mobility, disaster recovery,...

  • Page 5: Network Topologies

    • Easy management and maintenance—EVI requires deployment only on edge devices and does not introduce any topology change or configuration within sites or the transport network. Network topologies As shown in Figure 2, an EVI network has one or multiple edge devices at each site. These sites are connected through virtual links and run the EVI IS-IS protocol to advertise their MAC address entries to each other.

  • Page 6: Terminology

    Figure 3 Multiple EVI networks Site 2 Site 1 EVI 1 VLANs 100-101 Site 3 EVI 2 VLAN 4000 EVI 3 VLANs 50-80 Site 4 Site 5 Terminology Edge device An edge device performs typical Layer 2 learning and forwarding on the site-facing interfaces (internal interfaces) and performs tunneling and routing on the transport-facing interfaces.

  • Page 7: Working Mechanism

    ENDC An EVI neighbor discovery client works with an ENDS to learn neighbor information and triggers EVI link setup between neighbors. EVI IS-IS EVI IS-IS establishes adjacencies and advertises MAC reachability information among edge devices at different sites in an EVI network. It also maps VLANs to redundant edge devices at a multihomed site to avoid loops and balance traffic.
  • Page 8 • MAC entries learned through EVI IS-IS—After completing neighbor discovery, the edge devices run EVI IS-IS in the control plane to establish adjacencies and advertise MAC reachability information that has been learned or configured in the data plane to each other over EVI links.

  • Page 11: Selective Flood

    Site B's edge device de-encapsulates the ARP request and broadcasts the request. IP2 sends an ARP reply back to site A's edge device over the EVI link. Site A's edge device creates an ARP cache entry for the remote MAC address and forwards the reply to the requesting host.
  • Page 12 devices have a user-configurable DED priority. The one with the highest DED priority is elected as the DED. The DED uses the following rules to assign active VLANs: If an extended VLAN is configured only on one edge device, the edge device is the appointed edge forwarder for the VLAN.

  • Page 14: Path Mtu

    Path MTU When encapsulating an Ethernet frame in EVI, the edge device does not modify the Ethernet frame, but it sets the DF bit in the IP header. For an Ethernet transport network, the total size of an EVI protocol packet increases by 46 bytes, and the total size of a data packet increases by 38 bytes. Because EVI does not support path MTU discovery, your EVI deployment must make sure the path MTU of the transport network is higher than the maximum size of EVI tunneled frames.

  • Page 15: Configuring A Site Id

    Configuring a site ID A site ID uniquely identifies a site in an EVI network. Edge devices at the same site must use the same site ID, and edge devices at different sites must use different site IDs. A site ID conflict occurs in the following situations: •...
