Introduction

This document provides DRNI configuration examples.

Distributed Resilient Network Interconnect (DRNI) virtualizes two physical devices into one system for multichassis link aggregation. A remote aggregation system can connect to the member devices in the DRNI system through a multichassis link aggregation for node redundancy.

Prerequisites

The configuration examples 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.

The following information is provided based on the assumption that you have basic knowledge of DRNI.

Example: Configuring DRNI at the access layer

Network configuration

As shown in Figure 1:

·     Configure Device A and Device B as a DR system to establish one multichassis aggregate link with Device F and one with Device C and Device D.

·     Set up a keepalive link between Ten-GigabitEthernet 1/0/5 of Device A and Ten-GigabitEthernet 1/0/5 of Device B, and exclude the interfaces from the shutdown action by DRNI MAD.

·     Configure two VRRP groups on Device C and Device D to provide gateway services for VLAN 10 and VLAN 20.

¡     Configure VRRP group 1 to provide gateway services for hosts in VLAN 10 (Area A). Add Device C and Device D to the group as the master and backup devices, respectively.

¡     Configure VRRP group 2 to provide gateway services for hosts in VLAN 20 (Area B). Add Device D and Device C to the group as the master and backup devices, respectively.

·     Configure OSPF on Device C, Device D, and Device E for the hosts to communicate with external networks at Layer 3.

Analysis

For the secondary DR device to monitor the state of the primary device, establish a Layer 3 keepalive link between the DR member devices.

To balance traffic between two VRRP gateway devices, you can assign them to two VRRP groups with different priorities. In this example, Device C is assigned a higher priority than Device D in VRRP group 1 so Device C can become the master in this group. Device D is assigned a higher priority than Device C in VRRP group 2 so Device D can become the master in this group.

Restrictions and guidelines

DRNI restrictions and guidelines

For the DR member devices to be identified as one DR system, you must configure the same DR system MAC address and DR system priority on them. In addition, assign different DR system numbers to the DR member devices.

A DR member device can have only one IPP.

For correct keepalive detection, you must exclude the interfaces used for keepalive detection from the shutdown action by DRNI MAD.

VRRP restrictions and guidelines

You cannot specify the virtual IP address as any of the following IP addresses:

·     All-zero address (0.0.0.0).

·     Broadcast address (255.255.255.255).

·     Loopback address.

·     IP address of other than Class A, Class B, and Class C.

·     Invalid IP address (for example, 0.0.0.1).

Make sure the virtual IP address assigned to an IPv4 VRRP group is from the same subnet as the downlink interface IP addresses of its group members.

Example: Configuring DRNI at the distribution layer

Network configuration

As shown in Figure 2:

·     Configure Device A and Device B as a DR system to establish one multichassis aggregate link with Device C and Device D.

·     Set up a keepalive link between Ten-GigabitEthernet 1/0/5 of Device A and Ten-GigabitEthernet 1/0/5 of Device B, and exclude the interfaces from the shutdown action by DRNI MAD.

·     Configure two VRRP groups on Device A and Device B to provide gateway services for VLAN 100 and VLAN 101.

¡     Configure VRRP group 1 to provide gateway services for hosts in VLAN 100 (Area A). Add Device A and Device B to the group as the master and backup devices, respectively.

¡     Configure VRRP group 2 to provide gateway services for hosts in VLAN 101 (Area B). Add Device B and Device A to the group as the master and backup devices, respectively.

·     Configure OSPF on Device A, Device B, and Device E for the hosts to communicate with external networks at Layer 3.

Analysis

For the secondary DR device to monitor the state of the primary device, establish a Layer 3 keepalive link between the DR member devices.

To balance traffic between two VRRP gateway devices, you can assign them to two VRRP groups with different priorities. In this example, Device A is assigned a higher priority than Device B in VRRP group 1 so Device A can become the master in this group. Device B is assigned a higher priority than Device A in VRRP group 2 so Device B can become the master in this group.

Restrictions and guidelines

DRNI restrictions and guidelines

For the DR member devices to be identified as one DR system, you must configure the same DR system MAC address and DR system priority on them. In addition, assign different DR system numbers to the DR member devices.

A DR member device can have only one IPP.

For correct keepalive detection, you must exclude the interfaces used for keepalive detection from the shutdown action by DRNI MAD.

VRRP restrictions and guidelines

You cannot specify the virtual IP address as any of the following IP addresses:

·     All-zero address (0.0.0.0).

·     Broadcast address (255.255.255.255).

·     Loopback address.

·     IP address of other than Class A, Class B, and Class C.

·     Invalid IP address (for example, 0.0.0.1).

Make sure the virtual IP address assigned to an IPv4 VRRP group is from the same subnet as the downlink interface IP addresses of its group members.
