• Supports Broadcast, Non-Broadcast Multi-Access, Point-to-Multi-point and Point-to-Point links (both numbered and unnumbered)
• Supports configuration of Virtual Link Networks
• Provides OSPF area/stub area support
• Supports redistribution of static routes and routes learnt through BGP and RIP. The route exchanges with BGP conforms to the RFC 1745
• Supports advertising Secondary Addresses of an interface
• Provides configuration for aggregating external routes at the ASBR
• Support for passive interfaces
• Fully compatible with Aricent's IP and SNMP agents
• Uses an independent radix tree based library (Trie) for easy creation, maintenance, and access of routing entries
• Supports simple password and cryptographic packet authentication using the MD5 algorithm
• Supports Equal-Cost Multi-Path routing
• Handles database overflow
• Provides Demand Circuit support
• Provides Opaque LSA support
• Provides NSSA support
• Supports alternative implementations of OSPF Area Border routers
• Provides flexible choice of synchronous (socket) or asynchronous (function call-based) interfaces with the IP module
• Provides complete support for SNMP-based management by implementing the MIB in the RFC 1850 and proprietary MIBs
• Highly portable code that uses flexible buffer and timer management libraries

OSPF-TE (with Traffic Engineering capabilities) is an optional feature. Aricent's OSPF is available with or without OSPF-TE

Features of OSPF-TE:

• Supports formation of the Traffic Engineering database
• Provides flexible CSPF query interface to applications for calculating the Constraint based Shortest Path using the Traffic Engineering database. The application provides the following constraints for the CSPF calculation:
• Ingress Router ID (Source)
• Egress Router ID (Destination)
• The minimum bandwidth required on all the links in the path
• The priority level of a link
• TE Metric (Path Metric) ensuring that the resultant path’s metric is not greater than the requested metric
• Hop Count ensuring that the resultant path’s number of hops is not greater than the specified number
• Include All Set: This is a set of administrative groups
• Include Any Set: This is a set of resource administrative groups
• Exclude Any Set: This is a set of administrative groups
• Link Protection Type
• Switch Capability for the GMPLS interfaces
• Encoding Type of the GMPLS interfaces
• Bi-directional/Unidirectional (Symmetric) specifying whether the same constraints need to be applied for the reverse path for each link in the path
• Requests for one primary path and one secondary path in a single CSPF request. The secondary path calculation can have diversity (Node disjoint, link disjoint, and SRLG disjoint) as another input
• Provides a single strict/loose explicit route
• For strict explicit route, the CSPF ensures that the resultant path uses all the hops specified in the explicit route, which are present in the path, in the same order in which the application had specified
• For loose explicit route, the CSPF ensures that the resultant path uses all the hops specified in the explicit route, which are present in the path, but may also have additional hops in between two hops specified in the explicit input. This option results in a single path calculation
• Provides a primary path and request for a secondary path with the required diversity
• Provides a primary path and asks for a segment protection path (new path to be calculated for a segment of the primary path)
