Rapid Dual
Homing
Rapid Dual Homing is an important feature of Rapid Super Ring redundancy technology.
When you want to connect multiple RSR or form redundant topology with other vendors,
RDH allows you to have a maximum of seven multiple links for redundancy without any
problem.
In RDH, you do not need to configure a specific port to connect to other protocol. The RDH
selects the fastest link for the primary link and blocks all the other links to avoid a loop.
If the primary link failed, RDH automatically forwards the secondary link for a network
redundant. If there are more connections, they are standby links and are recovered if
both primary and secondary links are broken.
Ring status To Enable/Disable the Ring, remember to enable the Ring after you add it.
