Configuring Arp Mad - HP 6125G Configuration Manual

NOTE:
After a BFD MAD-enabled IRF fabric splits, route conflict messages (for example, %May
16:15:47:733 2010 HP ARP/3/ROUTECONFLICT: Slot=5;Route conflict found,
IP:192.168.2.1, VrfIndex:0) might appear on the fabric part that does not have the original
master, because this fabric part still keeps the forwarding entries with the original master as the
destination. This message does not affect forwarding. The system stops generating it after the forwarding
entries are aged out.

Configuring ARP MAD

When you configure ARP MAD, follow these guidelines:
If an intermediate device is used, you can use common data links as ARP MAD links. If no
•
intermediate device is used, set up dedicated ARP MAD links between IRF member devices.
Use a VLAN dedicated to ARP MAD.
•
If an intermediate device is used, do the following:
•
Run the spanning tree feature between the IRF fabric and the intermediate device.
Enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
Create an ARP MAD VLAN and assign the ports on the ARP MAD links to the VLAN.
If the intermediate device is in an IRF fabric, assign this fabric a different domain ID than the
ARP MAD-enabled fabric to avoid false detection of IRF partition.
To configure ARP MAD:
Step
1. Enter system view.
2. Assign a domain ID to the IRF
fabric.
3. Create a VLAN dedicated to
ARP MAD.
4. Return to system view.
5. Enter Ethernet interface view
or interface range view.
Command

irf domain domain-id
vlan vlan-id
quit
•
Enter interface range view:
Approach 1:
interface range { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5>
Approach 2:
interface range name name
[ interface { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5> ]
•
Enter Ethernet interface view:

Remarks
N/A
The default IRF domain ID is 0.
The default VLAN on the device
is VLAN 1.
N/A
To assign a range of ports to the
BFD MAD VLAN, enter interface
range view.
To assign one port to the BFD
MAD VLAN, enter Ethernet
interface view.
