Configuring BFD MAD
Before you configure BFD MAD, choose a BFD MAD link scheme as described in "
As a best practice, connect the BFD MAD links after you finish the BFD MAD configuration.
When you configure BFD MAD settings, follow these restrictions and guidelines:
Category
Restrictions and guidelines
BFD MAD VLAN
•
Do not enable BFD MAD on VLAN-interface 1.
•
If you are using an intermediate device, perform the following tasks on
both the IRF fabric and the intermediate device:
Create a VLAN and VLAN interface for BFD MAD.
Assign the ports of BFD MAD links to the BFD MAD VLAN.
•
Make sure the IRF fabrics on the network use different BFD MAD VLANs.
•
Make sure the BFD MAD VLAN contains only ports on the BFD MAD
links. Exclude a port from the BFD MAD VLAN if the port is not on the
BFD MAD link. For example, if you have assigned the port to all VLANs
by using the
port trunk permit vlan all
command, use the
undo port
trunk permit
command to exclude the port from the BFD MAD VLAN.
BFD MAD VLAN and
feature compatibility
Do not use the BFD MAD VLAN for any purpose other than configuring BFD
MAD.
•
Configure only the
mad bfd enable
and
mad ip address
commands on
the VLAN interface used for BFD MAD. If you configure other features,
both BFD MAD and other features on the interface might run incorrectly.
•
Disable the spanning tree feature on all Layer 2 Ethernet ports in the BFD
MAD VLAN. The MAD feature is mutually exclusive with the spanning
tree feature.
MAD IP address
•
Use the
mad ip address
command instead of the
ip address
command
to configure MAD IP addresses on the BFD MAD-enabled VLAN
