Multi-Link Dual-Homing makes is possible for a WeOS dual-homing node to have
redundant connections to an FRNT ring.
Fig. 15.4 shows an example where two
dual-homing nodes are connected to the FRNT ring with two connections each.

Figure 15.4: Dual-Homing with single FRNT ring (super-ring). (a) and (b) show the
same topology in different ways.
Consider one of the dual-homing nodes in fig. 15.4a , assuming it is a WeOS switch
with Ethernet ports ’1’ and ’2’ as uplinks, and where port ’1’ is to be active by
default. A possible configuration is given below:
Example
example:/#> configure
example:/config/#> dual-homing
Creating new instance 1
example:/config/dual-homing-1/#> uplink 1
example:/config/dual-homing-1/uplink-eth1/#> priority 100
example:/config/dual-homing-1/uplink-eth1/#> end
example:/config/dual-homing-1/#> uplink 2
example:/config/dual-homing-1/uplink-eth2/#> leave
Starting Ring bridging/dual-homing daemon .................. [ OK ]
Configuration activated.
Remember "copy run start" to save to flash (NVRAM).
