•
All member devices in the IRF fabric must have the same acl ipv6 enable (or acl ipv6 disable)
command setting. For more information about acl ipv6, see ACL and QoS Configuration Guide.
•
All member devices in the IRF fabric must have the same setting for the acl mode command. For
more information about acl mode, see ACL and QoS Configuration Guide.
•
All member devices in the IRF fabric must have the same vpn popgo command setting. For more
information about vpn popgo, see MPLS Configuration Guide.
•
All member devices in the IRF fabric must have the same portal-roaming enable command setting.
For more information about Portal, see Security Configuration Guide.
•
All member devices in the IRF fabric must have the same irf mode enhanced command
configuration. For more information about enhanced IRF mode, see "
" and "
Enabling enhanced IRF mode in IRF mode
MAD
•
LACP MAD handles collisions in a different way than BFD MAD and ARP MAD. To avoid conflicts,
do not use LACP MAD together with BFD MAD and ARP MAD. However, you can configure BFD
MAD and ARP MAD together for prompt IRF split detection.
•
If LACP or ARP MAD runs between two IRF fabrics, assign each fabric a unique IRF domain ID. For
BFD MAD, this task is optional.
•
To exclude a port from the shutdown action that is executed when an IRF fabric transits to the
Recovery state, use the mad exclude interface command. To bring up a port after the IRF fabric
transits to the Recovery state, you must use the mad restore command instead of the undo shutdown
command to activate the entire IRF fabric.
Other configuration guidelines
•
If a subordinate device uses the same next-startup configuration file name as the master device, the
file might be overwritten depending on your configuration file management settings. To continue to
use the configuration file after removing the device from the IRF fabric, back up the file before setting
up the IRF fabric.
•
Strictly follow the IRF fabric setup procedure described in "
Setup and configuration task list
" to plan
the IRF fabric, identify IRF physical ports, connect IRF member devices, and configure basic settings.
•
Assign each member a unique IRF member ID to make sure they can merge. You must reboot the
members to validate the IRF member ID settings.
•
If two IRF fabrics have the same bridge MAC address, they cannot merge.
•
Assign the highest member priority to the device you want to use as the master.
•
Assign the IRF fabric a unique IRF domain ID in a multi-IRF network.
•
Save any configuration you have made to the startup configuration file before rebooting the IRF
member devices.
