Dears all,

at one site i have 4 PPPOE WAN connections terminated on our PLB device. and now i want to apply HA at this site,

the question is:
do i need to have 4 switches, each of them connected to one of the WAN cables, or i can connect all WANs to one switch then connect this switch to our devices “cable from Switch-to-PLB for each WAN” ?

as the Diagram billow for 2 WANs for example:

Hi Basher, you will need either one switch for each WAN or one switch that is capable of port-based VLAN’s.
