We're relocating a data centre and potentially a large number of VLANs need to be spanned. My ASR has accepted "service instance 1 ethernet" to "service instance 4000 ethernet" commands. But is there a practical limit to the number of VLANs I should be configuring on the ASR using OTV.
The router is an ASR 1001-HX (x2). I see there are no limitations documented. But each ethernet service instance presumably uses a PVST. Could that be a limitation? MST would probably avoid that.
