Gatekeepers - how many zones, prefixes, clusters...

[pgasparovic]

Hi there,

I've spotted some limitations in some Cisco docs while reading them about max. number of configured zones (local, remote), zone prefixes, clusters and elements per cluster. Is some common document out there which describes the limitations, and if not, can anybody tell me what they are, also whether it is related to amount of free DRAM in GK ?

Thanks much for prompt answer.

Clustered gatekeepers communicate via Gatekeeper Update Protocol (GUP).The number of GKs in a cluster is limited to 5. One reason for this could be, as it could lead to a n^2 problem. And as far as the number of zones, prefixes are considered, other than the memory constraints I don't see any issues in configuring zones/prefixes.
