11.3.3 Binding the Remote Backup Profile to the Interface

The remote backup policy bound to an interface must be created in the system view. Otherwise,
the binding fails.
Context
Perform the following steps on the devices that back up each other:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed. The interface is a VRRP-capable interface connected to the host.
Step 3 Run:
remote-backup-profile profile-name
The remote backup profile is bound to the interface.

11.3.4 Configuring a Device to Automatically Enable ARP Dual-
Device Hot Backup in E-Trunk Master/Backup Scenarios
This section describes how to configure a device to automatically enable ARP dual-device hot
backup in E-Trunk master/backup scenarios.
Context
L2VE+L3VE or L2GVE+L3GVE L2VPN termination and L3VPN access using L2VPN are
deployed. An Eth-Trunk joins an E-Trunk, and an L2VE interface joins the Eth-Trunk or an
Issue 02 (2014-09-30)
NOTE
The VRRP interfaces of the master and backup routers must be configured with the same VLAN ID.
Otherwise, ARP entries cannot be backed up. The details are as follows:
l If the master and backup router use common VLANs, the same VLAN ID must be set for the VLANs
using the vlan-type dot1q vlan-id command.
l If the master and backup routers use QinQ termination sub-interfaces, the same range of VLAN IDs
in tags of packets to be terminated must be set using the qinq termination pe-vid pe-vid ce-vid { low-
ce-vid [ to high-ce-vid ] } [ vlan-group group-id ] command.
NOTE
When dual-system ARP hot backup is used, note the following issues:
l Running the vrrp vrid virtual-router-id preempt-mode timer delay delay-value command in the view
of the interface in the master state to set the switchback delay to 2 minutes.
l If the undo vrrp vrid virtual-router-id command is run in the interface view to delete the virtual IP
address, run the undo remote-backup-profile profile-name command in the interface view to delete
the remote backup profile.
