We are doing an upgrade to one of our client's HQ with the following topology:
22-story building with 11 EAPS instances coming from the cores (couple of x650's on a stack with core license) distributed to all the other switches in the building (x450's and x350's with edge license).
Going with the recommended release of EXOS 126.96.36.199-patch1-10 (our current firmware is 188.8.131.52 and 184.108.40.206 on our cores). I've checked the release notes for that release and I dont see anything that could affect us with EAPS or ELRP, but we have our doubts.
Are main questions are:
Could there be any problem with the re-convergence of the eaps rings, once we start upgrading and rebooting our switches one by one?
Should we start the upgrade from our access switches and then advance towards our core switches or start from the core? Is there any best practice for this?
Does ELRP gets affected in any way (Dont think so, but our client is concerned about this too)?
Thanks in advance.
