OcNOS 6.4 for Service Providers: CLI Management, EVPN Scale, and Access Improvements

OcNOS 6.4 for Service Providers is now generally available. This release delivers improvements across the full SP use case portfolio — from access routers and cell site routers through aggregation and core — with a focus on network management, operational efficiency, and scale for large SP deployments.

CLI Management Enhancements

The OcNOS command-line interface is consistently described by SP engineers as "industry-standard" — familiar to anyone with Cisco or Juniper experience. OcNOS 6.4 expands this with improved structured output across all major show commands, making it easier to feed OcNOS data into automation pipelines and network management systems.

! OcNOS 6.4 SP -- Enhanced show command output examples
!
! BGP summary with improved formatting:
show bgp summary
! Now includes: peer group state, prefix counts, convergence timing

! IS-IS adjacency detail (the adjacency view is a CLNS command):
show clns neighbors detail

! EVPN instance state:
show evpn mpls tunnel

! Interface counters in structured format:
show interface eth-0-1 counters

! Route table with prefix filtering:
show ip route 10.0.0.0/8 longer-prefixes

NETCONF YANG Model Expansion

OcNOS 6.4 expands NETCONF YANG model coverage for SP use cases, adding models for:

• IS-IS instance configuration and state
• BGP peer group management
• MPLS label space management
• Interface queue statistics

! OcNOS 6.4 SP -- NETCONF configuration push example
!
! Enable the NETCONF server first:
configure terminal
feature netconf-ssh vrf management
commit
exit
!
! Query IS-IS adjacencies via NETCONF (YANG model):
! <get>
!   <filter type="subtree">
!     <routing xmlns="urn:ietf:params:xml:ns:yang:ietf-routing">
!       <control-plane-protocols>
!         <control-plane-protocol>
!           <isis xmlns="urn:ietf:params:xml:ns:yang:ietf-isis">
!             <adjacencies/>
!           </isis>
!         </control-plane-protocol>
!       </control-plane-protocols>
!     </routing>
!   </filter>
! </get>
!
! Verify the NETCONF server:
show netconf server

EVPN Multi-homing Stability

OcNOS 6.4 SP improves EVPN Ethernet Segment Designated Forwarder (DF) election stability, reducing unnecessary DF re-elections during transient topology events. This improves service availability for multi-homed CE deployments where DF flaps caused brief traffic interruptions in earlier releases.

! OcNOS 6.4 SP -- EVPN multi-homing
!
! The Ethernet Segment is configured on the multi-homed interface itself,
! not in a separate ethernet-segment submode.
configure terminal
!
interface po111
  evpn multi-homed esi 00:00:00:11:11:aa:aa:00:00 load-balancing single-active
  exit
!
commit
exit
!
! Verify the multi-homing state:
show evpn multi-homing
show evpn multihoming-status
show bgp l2vpn evpn summary

BGP Convergence Improvements

OcNOS 6.4 SP improves BGP route processing performance for operators running full internet routing tables (900K+ prefixes). Processing time for large BGP UPDATE bursts is reduced, improving convergence speed after BGP session resets or peer reconnections.
