Smart Link and CFD collaboration configuration example
Network requirements
As shown in Figure 31:
• Router A, Router B, Router C, and Router D form a maintenance domain (MD) of level 5. Router C
is a Smart Link device, and Router A, Router B, and Router D are associated devices. Traffic of
VLANs 1 through 200 on Router C is dually uplinked to Router A by Router B and Router D.
• Configure the CFD CC function for Smart Link so that traffic of VLANs 1 through 100 is uplinked to
Router A by Router C through GigabitEthernet 3/0/1 (primary port of smart link group 1). Traffic of
VLANs 101 through 200 is uplinked to Router A by Router C through GigabitEthernet 3/0/2
(primary port of smart link group 2). When the link between Router C and Router A fails, traffic is
rapidly switched to the secondary port of each smart link group, and switched back to the primary
ports after the fault is cleared.
