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.

Table 5-33: 7701 CPAA Hardware revision 2 and vCPAA scalability

Item description

Scaling

Maximum Number of Routers Supported with both IGP and BGP turned-on in the same 7701 CPAA (larger node count must use two separate 7701 CPAAs for IGP and BGP) with 2 200 000 BGP combined routes

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)
