Collocated L2Border + Edge?

[Sylvain_Che]

Dear,

I know it might not be the best design, but could a L2Border be collocated with Edge Node role? Is it supported?

Thanks,

Sylvain.

Actually found the answer from CVD:

Devices operating with an edge node role, including Fabric in a Box, are not supported with Layer 2 border handoff.

still there are SDA transits for L2-LANs via Fabric (of course with gateway outside the Fabric) etc.
it may fit your need

yeah, answer to Q is in the Q itself: not best designs are not supported in SDA :0D

Sorry for slow reply. Edge Node and L2BN are more or less the same thing, that's why they cannot co-exist on the same device. Instead, on the FIAB, use the SDA access VLAN as the L2HO VLAN. For example, in host oboarding UI, make FIAB port X a trunk, and then connect that trunk to the non-SDA network e.g. a firewall or a router or a switch. Hope that makes sense.
