Usage guidelines
BFD MAD uses the BFD protocol to detect multi-active collisions. This MAD mechanism can work
with or without intermediate devices.
When you configure BFD MAD on a Layer 3 aggregate interface, follow these restrictions and
guidelines:
Category
BFD MAD-enabled Layer 3
aggregate interface
BFD MAD VLAN
Restrictions and guidelines
The aggregate interface must operate in static aggregation mode.
•
On the intermediate device (if any), assign the ports on the BFD MAD
links to the same VLAN. Do not assign the ports to an aggregate
interface. If these ports are hybrid ports, make sure these ports are
untagged members of their PVIDs.
•
If the intermediate device acts as a BFD MAD intermediate device for
multiple IRF fabrics, assign different BFD MAD VLANs to the IRF fabrics.
•
Do not use the BFD MAD VLAN on the intermediate device for any
purposes other than BFD MAD.
•
Make sure the BFD MAD VLAN on the intermediate device contains only
ports on the BFD MAD links. Exclude a port from the BFD MAD VLAN if
that port is not on a BFD MAD link. If you have assigned that port to all
VLANs by using the port trunk permit vlan all command, use the undo
port trunk permit command to exclude that port from the BFD MAD
VLAN.
