Introduction
This document provides DRNI configuration examples.
Distributed Resilient Network Interconnect (DRNI) virtualizes two physical devices into one system through multichassis link aggregation. The standard for DRNI is IEEE P802.1AX-REV™/D4.4c, Draft Standard for Local and Metropolitan Area Networks.
DRNI is typically applicable to data center environments.
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.
General restrictions and guidelines
DR system restrictions and guidelines
· A DR system supports only two DR member devices.
· Make sure the DR member devices are consistent in type 1 configuration, which includes the global and DR interface specific settings listed in Table 1 and Table 2, respectively.

· If you attach a device to a DR system through a single link, attach it to the primary DR device. If you attach the device to the secondary DR device, traffic interruption will occur after the DR system splits.
· The data restoration interval specifies the maximum amount of time for the secondary DR device to synchronize data (including MAC and ARP entries) with the primary DR device during DR system setup. Make sure the data restoration interval is longer than the time required for the secondary DR device to start up and restore the table entries.
· As a best practice to avoid DR system split, do not modify the DR system MAC address, system number, or system priority of DR member devices after the DR system is established.
· For DR member devices to synchronize ARP entries, you must exclude the VLAN interfaces of the VLANs to which the DR interfaces and IPPs belong from the DRNI MAD DOWN action.
DR interface restrictions and guidelines
· You can configure only Layer 2 aggregate interfaces as DR interfaces.
· As a best practice, assign Layer 2 aggregate interfaces to a DR group with the same number as their interface numbers.
· Do not use automatic assignment or automatic link aggregation on the Layer 2 aggregate interfaces that act as DR interfaces.
· As a best practice, disable spanning tree on DR interfaces.
IPP restrictions and guidelines
· Do not use automatic assignment or automatic link aggregation on the Layer 2 aggregate interfaces that act as IPPs.
· As a best practice, configure IPPs as trunk ports and assign them to all VLANs that are permitted on DR interfaces. For the DR member devices to have Layer 3 connectivity over the IPL, create VLAN interfaces for those VLANs and assign IP addresses to them.
· To avoid multi-active collisions, use interfaces on different cards to set up the IPL and keepalive link.
Keepalive link restrictions and guidelines
· Use Layer 3 physical interfaces to set up the keepalive link. As a best practice, use management Ethernet interfaces.
· To avoid multi-active collisions, use interfaces on different cards to set up the IPL and keepalive link.
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 HundredGigE 1/0/5 of Device A and HundredGigE 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.

Release 6555P01 |
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. You must 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
As a best practice, use VRRP standard mode.
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).
The virtual IP address of an IPv4 VRRP group must be on the same subnet as the downlink interface IP addresses of the VRRP group members to ensure successful traffic forwarding.

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 HundredGigE 1/0/5 of Device A and HundredGigE 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.
For Device A to be the master in VRRP group 1, assign it a higher priority than Device B. For Device B to be the master in VRRP group 2, assign it a higher priority than Device A.

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. You must assign different DR system numbers to 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.
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
As a best practice, use VRRP standard mode.
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).
The virtual IP address of an IPv4 VRRP group must be on the same subnet as the downlink interface IP addresses of the VRRP group members to ensure successful traffic forwarding.
