Restrictions and guidelines
a VRRP virtual address on the BFD MAD-enabled VLAN interface.
•
Make sure all the MAD IP addresses are on the same subnet.
•
MAD IP addresses must be unique among all IP addresses on the IRF
fabric.
Set the IRF link down report delay to 0 seconds to avoid unnecessary
recalculations.
Restrictions and guidelines
Use the first management Ethernet port on the active MPU of each member
device to set up BFD MAD links.
If you are using an intermediate device, use common Ethernet ports on the
intermediate device to set up BFD MAD links.
•
On the intermediate device (if any), create a VLAN for BFD MAD, and
assign the ports used for BFD MAD to the VLAN. On the IRF fabric, you
do not need to assign the management Ethernet ports to the VLAN.
•
As a best practice, do not configure other features on the VLAN used for
BFD MAD.
•
Make sure the IRF fabrics on the network use different BFD MAD
VLANs.
•
Make sure the BFD MAD VLAN on the intermediate device contains only
ports on the BFD MAD links.
Do not bind a BFD MAD-enabled management Ethernet port to a VPN
instance. The MAD feature is mutually exclusive with VPN.
•
Use the mad ip address command instead of the ip address command
to configure MAD IP addresses on the BFD MAD-enabled management
Ethernet ports.
•
Make sure all the MAD IP addresses are on the same subnet.
•
MAD IP addresses must be unique among all IP addresses on the IRF
fabric.
Set the IRF link down report delay to 0 seconds to avoid unnecessary
recalculations.
