Routing and Security Enhancements
BGP VRF Export-Map Enhancement
OcNOS now supports route-map–based export filtering and attribute modification at the VRF level. Administrators can apply route-maps to VRFs to filter exported routes using match conditions and adjust key BGP attributes with set clauses before the routes leave the VRF. This provides more granular control over inter-VRF route export policies, enhances security, and improves traffic engineering.

BGP RT-Filter Visibility Enhancements
OcNOS introduces two new commands, show ip bgp rtfilter neighbors <prefix> advertised-routes and show ip bgp rtfilter neighbors <prefix> received-routes, to display BGP Route-Target (RT) filter routes advertised to or received from a specific neighbor. These commands enhance visibility and make troubleshooting RT-filter route exchanges easier.
For more details, refer to the show ip bgp rtfilter neighbors command in the OcNOS Layer 3 Guide, Release 7.0.0.

IGMP Offlink Log Suppression
OcNOS adds a new per-interface CLI option log-suppress to the ip igmp offlink command. When configured, warning messages for IGMP reports from non-local subnets are suppressed entirely, reducing log volume in environments with many offlink receivers.

BGP Labeled Unicast Next Hop in Route-Map
BGP Labeled Unicast Next Hop in Route-Map provides the ability to selectively set the next hop value to self, and the label attributes of the matched routes are replaced with the local BGP peer address and the local label.

Optimized Debug Logging via Background Debug Recording (BDR)
Introduced the Background Debug Recording (BDR) feature to optimize debug logging performance by storing debug logs in an in-memory buffer instead of writing them directly to disk, and periodically or manually flushing them to log files to reduce I/O overhead. This enables users to keep debugging active during testing without impacting system performance or requiring test reruns. In the event of a crash, in-memory logs can be retrieved for analysis. The feature supports configurable buffer sizes (1–10 MB), module-based logging, severity level selection, and optional suppression of non-BDR logs. BDR must be explicitly enabled and configured per module.

EVPN L3 Gateway with VXLAN Stitching
OcNOS supports Layer 3 EVPN Gateway Stitching, enabling seamless IP connectivity between independent VXLAN EVPN domains or VRFs without merging their control planes or Layer 2 broadcast domains. The feature uses EVPN Type-5 route stitching at border leaf or spine devices to facilitate scalable and secure inter-domain routing across multi-site data centers, multi-PoD fabrics, and hybrid cloud environments.
For more details, refer to the EVPN L3 Gateway with VXLAN Stitching section in OcNOS Virtual Extensible LAN Guide, Release 7.0.0.
Route Maps in BGP EVPN
Enables operators to apply route maps for the EVPN address family, including BGP L2VPN unnumbered mode. Allows matching on EVPN route-type and MAC lists to filter routes in IN and OUT directions, providing fine-grained policy control, selective advertisement of Type-5 prefixes, and flexible route management across EVPN networks.
For more information, refer to the section in the OcNOS Layer 3 Guide, Release 7.0.0.
