Introduction

This document provides examples for using EVI with MDC and IRF.

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.

EVI enables long-distance virtual machine workload mobility and data mobility, disaster recovery, and business continuity. For example, virtual machines can move between data center sites without changing their IP addresses, so their movements are transparent to users and do not disrupt traffic.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of EVI, MDC, and IRF.

General restrictions and guidelines

When you configure EVI, follow these restrictions and guidelines:

·          For an extended VLAN at a site, you must place the VLAN's gateway on the edge device at the local site rather than a remote site.

·          You must install licenses for EVI and MDC. Licenses include DATACENTER licenses and CAMPUS licenses. A DATACENTER license covers both EVI and MDC. A CAMPUS license covers only MDC.

Example: Configuring EVI with MDC

Network configuration

As shown in Figure 1:

·          Set up an EVI network to extend VLAN 1000 across two data center sites in different cities over an IP transport network. The gateways and IP addresses of servers or virtual machines in VLAN 1000 must not change after they are moved from one site to another.

·          Use MDCs on edge devices to separate EVI tunneling services from gateway services.

NOTE:

·      IP address of Loopback 0 is the source IP address of the EVI tunnel on each edge device.

·      VLAN-interface 10 and VLAN-interface 11 are interfaces connected to the transport network (the ISP network).

 

Analysis

To avoid IP address or gateway changes for virtual machines after inter-site migration, deploy VRRP as follows:

·          Configure MDC A2 and MDC B2 to form a VRRP group to provide gateway services at the virtual IP address 100.0.0.254 for VLAN 1000.

·          For MDC A2 to become the master, assign a priority of 110 to MDC A2 and configure MDC B2 to use the default priority 100.

·          For the EVI network to transmit VRRP protocol packets, enable selective flood for the destination MAC address of VRRP packets (0100-5e00-0012).

Restrictions and guidelines

When you configure EVI with MDC, follow these restrictions and guidelines:

 

Configuration

Restrictions and guidelines

EVI network ID

·         All edge devices must use the same network ID for the EVI tunnels in the same EVI network.

·         The EVI tunnels on an edge device must use different network IDs.

Extended VLAN

·         Extended VLANs assigned to different EVI networks cannot be duplicated.

·         To avoid data breach, ensure that all edge devices in an EVI network maintain the same extended VLANs.

Outgoing interface to the transport network

·         For data security, do not use VLAN-interface 1 as an outgoing interface. Remove transport-facing physical interfaces from VLAN 1.

·         Do not use the VLAN interface of an extended VLAN as an outgoing interface to the transport network.

MDC

To avoid loops, use physical links to connect the two MDCs on a device only after you have created the MDCs.

Example: Configuring EVI with IRF

Network configuration

As shown in Figure 2:

·          Set up an EVI network to extend VLAN 1000 across two data center sites in different cities over an IP transport network. The gateways and IP addresses of servers or virtual machines in VLAN 1000 must not change after they are moved from one site to another.

·          Deploy one IRF fabric as the EVI edge device in each site for high availability.

·          Use CEs as the gateways for VLAN 1000 in their respective sites.

100.0.0.2/24

 

 

NOTE:

·      IP address of Loopback 0 is the source IP address of the EVI tunnel on each edge device.

·      VLAN-interface 10 and VLAN-interface 11 are interfaces connected to the transport network (the ISP network).

 

Analysis

·          To avoid IP address or gateway changes for virtual machines after inter-site migration, deploy VRRP as follows:

¡  Configure CE A and CE B to form a VRRP group to provide gateway services at the virtual IP address 100.0.0.254 for VLAN 1000.

¡  For CE A to become the master, assign a priority of 110 to CE A and configure CE B to use the default priority 100.

¡  For the EVI network to transmit VRRP protocol packets, enable selective flood for the destination MAC address of VRRP packets (0100-5e00-0012).

·          For high availability, configure link aggregation for both uplinks and downlinks of the IRF fabrics.

Restrictions and guidelines

When you configure EVI with IRF, follow these restrictions and guidelines:

 

Configuration

Restrictions and guidelines

EVI network ID

·         All edge devices must use the same network ID for the EVI tunnels in the same EVI network.

·         The EVI tunnels on an edge device must use different network IDs.

Extended VLAN

·         Extended VLANs assigned to different EVI networks cannot be duplicated.

·         To avoid data breach, ensure that all edge devices in an EVI network maintain the same extended VLANs.

Outgoing interface to the transport network

·         For data security, do not use VLAN-interface 1 as an outgoing interface. Remove transport-facing physical interfaces from VLAN 1.

·         Do not use the VLAN interface of an extended VLAN as an outgoing interface to the transport network.

IRF

In IRF mode, any type of outbound policies (for example, the outbound QoS policy) on an interface does not take effect on packets that are received from an EVI tunnel.

Spanning tree

The spanning tree feature and BFD MAD are mutually exclusive. You must disable the spanning tree feature on the IRF fabrics.

[CEB-Vlan-interface1000] vrrp vrid 1 virtual-ip 100.0.0.254

[CEB-Vlan-interface1000] quit

 

 

NOTE:

The virtual IP address of the VRRP group must be the same as the address configured for VRRP group 1 on CE A.

 

Verifying the configuration

# Move a server (100.0.0.100) from site 1 to site 2 without changing its IP address. (Details not shown.)

# Verify that the server can be pinged.

C:\>ping 100.0.0.100
