drni auto-recovery reload-delay

Use drni auto-recovery reload-delay to enable DR system auto-recovery and set the reload delay timer.

Use undo drni auto-recovery reload-delay to restore the default.

Syntax

drni auto-recovery reload-delay delay-value

undo drni auto-recovery reload-delay

Default

DR system auto-recovery is disabled and the reload delay timer is not set.

Views

System view

Predefined user roles

network-admin

Parameters

delay-value: Specifies a reload delay in the range of 240 to 3600 seconds.

Usage guidelines

This command is available in R2612 and later.

If only one DR member device recovers after the entire DR system reboots, auto-recovery enables that member device to take over the primary role when the reload delay timer expires. Then, the member device can forward traffic through its DR interfaces.

If auto-recovery is disabled, that DR member device will be stuck in the None role with all its DR interfaces being down after it recovers.

If both DR member devices recover after the entire DR system reboots, active-active situation might occur if both IPL and keepalive links were down when the reload delay timer expires. If this rare situation occurs, examine the IPL and keepalive links and restore them.

Examples

# Enable DR system auto-recovery and set the reload delay timer to 245 seconds.

<Sysname> system-view

[Sysname] drni auto-recovery reload-delay 245

Default

DRNI performs configuration consistency check.

Views

System view

Predefined user roles

network-admin

Usage guidelines

To ensure that the DR system can operate correctly, DRNI by default performs configuration consistency check when the DR system is set up.

Configuration consistency check might fail when you upgrade the DR member devices in a DR system. To prevent the DR system from falsely shutting down DR interfaces, you can temporarily disable configuration consistency check.

You must make sure the DR member devices use the same setting for configuration consistency check.

Examples

# Disable DRNI from performing configuration consistency check.

[Sysname] drni consistency-check disable

drni drcp period short

Use drni drcp period short to enable the short DRCP timeout timer (3 seconds) on the IPP or a DR interface.

Syntax

undo drni drcp period

Default

An aggregate interface uses the long DRCP timeout timer (90 seconds).

Predefined user roles

network-admin

Usage guidelines

This command takes effect only on the IPP or a DR interface.

DRCP uses a timeout mechanism to specify the amount of time that an IPP or DR interface must wait to receive DRCPDUs before it determines that the peer interface is down. This timeout mechanism provides the following timer options:

·     Short DRCP timeout timer, which is fixed at 3 seconds. If this timer is used, the peer interface sends one DRCPDU every second.

·     Long DRCP timeout timer, which is fixed at 90 seconds. If this timer is used, the peer interface sends one DRCPDU every 30 seconds.

Short DRCP timeout timer enables the DR member devices to detect a peer interface down event more quickly than the long DRCP timeout timer. However, this benefit is at the expense of bandwidth and system resources.

To avoid traffic interruption during an ISSU or DRNI process restart, disable the short DRCP timeout timer before you perform an ISSU or DRNI process restart. For more information about ISSU, see Fundamentals Configuration Guide.

Examples

# Enable the short DRCP timeout timer on Bridge-Aggregation 1.

Syntax

drni keepalive { ip | ipv6 } destination { ipv4-address | ipv6-address } source { ipv4-address | ipv6-address } [ udp-port udp-number ]

undo drni keepalive { ip | ipv6 }

Default

The destination and source IP addresses are not specified for DR keepalive packets, and the keepalive destination UDP port is 6400.

Views

System view

Predefined user roles

network-admin

Parameters

ip: Specifies IPv4 addresses.

ipv6: Specifies IPv6 addresses.

destination: Specifies an IP address of the DR peer as the destination IP address of keepalive packets.

source: Specifies a local IP address as the source IP address of keepalive packets.

ipv4-address: Specifies an IPv4 address.

ipv6-address: Specifies an IPv6 address.

udp-port udp-number: Specifies the destination UDP port of keepalive packets. The value range for the udp-number argument is 1 to 65535, and the default value is 6400.

Usage guidelines

The device accepts only keepalive packets that are sourced from the specified destination IP address. The keepalive link goes down if the device receives keepalive packets sourced from any other IP addresses.

Make sure the DR member devices in a DR system use the same keepalive destination UDP port.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Specify the destination and source IP addresses of keepalive packets as 192.168.68.125 and 192.168.68.100, respectively.

udp-port udp-number: Specifies the destination UDP port of keepalive packets. The value range for the udp-number argument is 1 to 65535. If you do not specify a UDP port number, 6400 is used.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If the keepalive packets belong to the public network, do not specify a VPN instance.

Usage guidelines

The device accepts only keepalive packets that are sourced from the specified destination IP address. The keepalive link goes down if the device receives keepalive packets sourced from any other IP addresses.

Make sure the DR member devices in a DR system use the same keepalive destination UDP port.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Specify the destination and source IP addresses of keepalive packets as 192.168.68.125 and 192.168.68.100, respectively.

<Sysname> system-view

[Sysname] drni keepalive ip destination 192.168.68.125 source 192.168.68.100

Predefined user roles

network-admin

Parameters

value: Specifies a timer value in the range of 3 to 10 seconds.

Usage guidelines

 

IMPORTANT

IMPORTANT:

For the DR member device to correctly determine the cause of an IPL down event, make sure the keepalive hold timer is longer than the keepalive interval and is shorter than the keepalive timeout timer.

 

The keepalive hold timer starts when the IPL goes down. The keepalive hold timer specifies the amount of time that the device uses to identify the cause of an IPL down event.

·     If the device receives keepalive packets from the DR peer before the timer expires, the IPL is down because the IPL fails.

·     If the device does not receive keepalive packets from the DR peer before the timer expires, the IPL is down because the peer DR device fails.

Examples

# Set the keepalive hold timer to 5 seconds.

<Sysname> system-view

[Sysname] drni keepalive hold-time 5

drni keepalive interval

Use drni keepalive interval to set the DR keepalive interval and timeout timer.

Use undo drni keepalive interval to restore the default.

Syntax

drni keepalive interval interval [ timeout timeout ]

undo drni keepalive interval

Default

The DR keepalive interval is 1000 milliseconds, and the DR keepalive timeout timer is 5 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

interval interval: Specifies the keepalive interval, in the range of 100 to 10000 milliseconds.

timeout timeout: Specifies the keepalive timeout timer, in the range of 3 to 20 seconds. The local keepalive timeout timer must be two times the keepalive interval of the peer at minimum.

Usage guidelines

The device sends keepalive packets at the specified interval to its DR peer. If the device has not received a keepalive packet from the DR peer before the keepalive timeout timer expires, the device determines that the keepalive link is down.

You must configure the same DR keepalive interval on the DR member devices in a DR system.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the DR keepalive interval and timeout timer to 2000 milliseconds and 6 seconds, respectively.

<Sysname> system-view

[Sysname] drni keepalive interval 2000 timeout 6

Changing the keepalive interval might cause system setup failure. Continue? [Y/N]:y

drni mad exclude interface (R2612 and later)

Use drni mad exclude interface to exclude an interface from the shutdown action by DRNI MAD.

Use undo drni mad exclude interface to enable DRNI MAD to shut down an interface when a multi-active collision is detected.

Syntax

drni mad exclude interface interface-type interface-number

undo drni mad exclude interface interface-type interface-number

Default

No interfaces are manually excluded from the DRNI shutdown action.

Views

System view

Predefined user roles

network-admin

Parameters

interface-type interface-number: Specifies an interface by its type and number.

Usage guidelines

This command is available in R2612 and later.

When DRNI MAD detects a multi-active collision, DRNI shuts down all network interfaces on the secondary DR device except for the interfaces excluded from the MAD shutdown action by DRNI.

The interfaces excluded from the MAD shutdown action include:

·     Interfaces excluded automatically by the system. For example, management interfaces.

·     Interfaces excluded manually.

If an interface has been placed in DRNI MAD DOWN state, executing the drni mad exclude interface command cannot bring it up.

For correct keepalive detection, you must exclude the interfaces used for keepalive detection from the shutdown action by DRNI MAD. If the IPP is a tunnel interface, you must exclude the traffic outgoing interface for the tunnel from the shutdown action by DRNI MAD.

Examples

# Exclude Ten-GigabitEthernet 1/0/1 from the shutdown action by DRNI MAD.

<Sysname> system-view

[Sysname] drni mad exclude interface ten-gigabitethernet 1/0/1

Default

The data restoration interval is 30 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

value: Specifies the data restoration interval, in the range of 1 to 3600 seconds.

Usage guidelines

The data restoration interval specifies the maximum amount of time for the secondary DR device to synchronize data with the primary DR device during DR system setup. Within the data restoration interval, the secondary DR device sets all network interfaces to MAD DOWN state, except for the following interfaces:

·     IPP.

·     Management Ethernet interface.

·     Interfaces excluded from the MAD shutdown action.

When the data restoration interval expires, the secondary DR device brings up all network interfaces.

To avoid packet loss and forwarding failure, increase the data restoration interval if the amount of data is large or if an ISSU is to be performed between the DR member devices.

Examples

# Set the data restoration interval to 50 seconds.

<Sysname> system-view

[Sysname] drni restore-delay 50

drni role priority

Use drni role priority to set the DR role priority of the device.

Use undo drni role priority to restore the default.

Syntax

drni role priority priority-value

undo drni role priority

Default

The DR role priority of the device is 32768.

Views

System view

Predefined user roles

network-admin

Parameters

priority-value: Specifies the DR role priority, in the range of 0 to 65535. The lower the value, the higher the priority.

Usage guidelines

IMPORTANT

IMPORTANT:

To prevent a primary/secondary role switchover from causing network flapping, avoid changing the DR priority assignment after the DR system is established.

 

For features that require centralized traffic processing, a DR member device is assigned the primary or secondary role based on its DR role priority. The secondary DR device forwards the traffic of those features to the primary DR device for processing. If the DR member devices use the same DR role priority, the member device with a lower bridge MAC address is assigned the primary role.

Examples

# Set the DR role priority of the device to 66.

<Sysname> system-view

[Sysname] drni role priority 66

Views

System view

Predefined user roles

network-admin

Parameters

mac-address: Specifies a MAC address in the H-H-H format. The MAC address cannot be a multicast MAC address, all-zero MAC address, or all-F MAC address.

Usage guidelines

 

CAUTION

CAUTION:

Changing the DR system MAC address causes DR system split. When you perform this task on a live network, make sure you are fully aware of its impact.

 

The DR system MAC address uniquely identifies the DR system on the network. For the DR member devices to be identified as one DR system, you must configure the same DR system MAC address on them. As a best practice, use the bridge MAC address of one DR member device as the DR system MAC address.

Examples

# Configure the DR system MAC address as 0001-0001-0001.

<Sysname> system-view

[Sysname] drni system-mac 1-1-1

Changing the system MAC address might flap the intra-portal link and cause DR system setup failure. Continue? [Y/N]:y

CAUTION

CAUTION:

Changing the DR system number causes DR system split. When you perform this task on a live network, make sure you are fully aware of its impact.

 

You must assign different DR system numbers to the DR member devices in a DR system.
