CER - ERL membership

[alex goshtaei]

Hi All,

I'm configuring CER 7.0, and I am wondering what the best practice is for ERL membership. switch port or IP subnet? it seems IP subnet is simpler that switch membership.

we have a campus with 7 different buildings with 4 remote sites.

thanks for any suggestion

Personally, I like subnet-based myself.  I have used subnet-based to support a CER cluster that provided e911 services for approximately 11,000 phones across around a dozen building with anywhere between 4 and 10 floors.  I didn't have any issues.

But that is just my experience with CER.

HTH.

Bill
