NETBuilder Support for CIDR

Support for CIDR has been implemented on the NETBuilder:

• NETBuilder software implements BGP-4. Support for CIDR is a significant part of the improvements made to BGP-4.
• NETBuilder software uses a routing table structure that understands a network number advertised with a prefix that is shorter than the natural mask. The NETBuilder's routing table and forwarding process ignore the traditional IP address Class and are capable of accepting any network/mask combination that it receives.
• NETBuilder software is capable of performing aggregation by way of BGP-4 configuration parameters. Also, the OSPF AreaRange parameter allows VLSM-based aggregation to be performed within an autonomous system. The network administrator may specify exactly what network numbers and masks are advertised outside of each area or domain.
