CAUTION:
•
You cannot assign interfaces configured with the following features to an HDLC link bundle: IPv4
addresses, IPv4 unnumbered, IPv6 addresses, and Unicast Reverse Path Forwarding (uRPF). After an
interface is assigned to an HDLC link bundle, you cannot configure any of these features on the interface
either.
• An interface can belong to only one HDLC link bundle at any point in time. To assign an HDLC link
bundle member interface to another HDLC link bundle, remove the interface from the current HDLC link
bundle first.
• The link layer protocol of an interface to be assigned to an HDLC link bundle can only be HDLC. After
the interface is assigned to the HDLC link bundle, you are not allowed to change its link layer protocol.
• You can assign interfaces to a nonexistent HDLC link bundle as members.
• You can assign interfaces on different cards to the same HDLC link bundle.
• If you change the bundling priority of a member interface after the HDLC link bundle configuration is
finished, the router will determine the state of each member interface in the HDLC link bundle again.
• Before you assign an interface to an HDLC link bundle, do not configure Layer 3 features, such as MPLS
and VPN, on the interface. If the interface has been configured with Layer 3 features, remove the Layer
3 feature configuration first. After you assign an interface to an HDLC link bundle, you can configure
Layer 3 features only on the HDLC link bundle interface. If you mistakenly configure Layer 3 features on
a member interface, remove the Layer 3 feature configuration from the member interface first, and then
use the shutdown and undo shutdown commands on the HDLC link bundle interface to completely
remove the configuration.
• The peer interface directly connected to an HDLC link bundle member interface must also join the HDLC
link bundle.
• The bundle member-priority command and the bundle max-active links command usually need to be
used in conjunction, so that interconnected interfaces on two different routers can be both selected at the
same time and exchange traffic successfully.
