How i can connect those switches?

    Hi again,

    I have a new scenario.

    Today we have this link between BD and "A" and a eaps ring. (A-B-C-D-E-F-G-H-I-J-A) "A" is the master.

    Is it possible to pass this new link between BD and "D"? (the red one)

    I think that i will need to make another EAPS:
    (D-BD-A-B-C-D) "D" should be the master of this eaps.

    and a third ring will be needed? (BD-D-E-F-G-H-I-J-A-BD) with BD as master?

    Hi,

    I do not know if that topology is supported, because the two rings A-B-C-D-E-F-G-H-I-J-A and D-BD-A-B-C-D overlap on more than one common link (the overlap is A-B-C-D). EAPSv2 allows the use of one common link for several EAPS domains.

    If you connected BD to e.g. B and C, you would have a usual EAPS common link topology, with a new EAPS ring BD-B-C-BD and the common link B-C.

    Thanks,
    Erik

    Hi,

    What if you define the "red" port on the BD as a redundant port of the "black" port ?
    The BD will switch on the redundant if the primary link goes down.
    No trafic will pass through the red port if the black port is UP.

    How can i do that? Today the link between "BD - A" is a common link, no eaps, no nothing else. How can i do "BD - D" as backup of "BD - A" ?

    This surely will solve my problem!

    Hi gbs,

    You can refer following "Software-Controlled Redundant Ports (SRP)" section in EXOS user guide:

    Hi,

    Romain's suggestion above looks best and simple way to deploy your topology.

    If you want to deploy two EAPS ring, please refer the "EAPS Multiple Ring Topology" section in the EXOS user guide.
