[e-nsp] EAPS with ERPS access ring ...

[Erik Bais]

Hi Yury, 

The thing you need to keep in mind is that you can do ESRP across links that are in an EAPS ring, however ... 

Never (EVER!!) run ESRP (Master or slave) on an EAPS Master, as ESRP will override the EAPS blocking of the secondary port on the master, causing broadcasting (layer2) loops in your network. 

Second, you would probably want to look into enabling ESRP HA (Host Attached) mode on the EAPS ring ports on the boxes that are doing ESRP in the setup.  

You can have the ESRP Control vlan (and the member vlan's) across the complete EAPS ring also across the EAPS master, as long as you keep the EAPS Master switch out of the active ESRP configuration. You might need to check in large metro EAPS rings to the ESRP timers, but in a not too large campus, it should work. 

So to restate (did I state this already ? ) Do NOT enable ESRP or configure anything ESRP related on the EAPS Master.  

Have fun in your lab testing it out. 

Regards,
Erik Bais

Hi.

Have somebody any experience with EAPS and ERPS on access ring?
Documentation (Concept and Reference Guides) have very
little information about it.
