CPAM and vCPAA
Scaling guidelines for CPAM and vCPAA
The following section outlines the tested limits for the CPAM component of NFM-P.
Note: All CPAAs monitoring a contiguous network must belong to the same administrative domain.
The scalability of 7701 CPAA Hardware revision 2 and vCPAA is described in the following table.

Item description |
Scaling |
|---|---|
|

500 |
|
Maximum Number of IGP Routers per 7701 CPAA if BGP is deployed on separate 7701 CPAA (routers can all be in one or multiple areas and count includes Nokia P/PE & 3rd party routers) |

|
Maximum Number of OSPF Domains/Areas per 7701 CPAA |
One Administrative Domain per 7701 CPAA Up to 50 areas per 7701 CPAA |
