Core, PE and peering routers for the full internet table

IP Infusion delivers the IP core and peering router: OcNOS-SP preloaded on qualified routers that hold the full internet BGP table in hardware, validate routes with RPKI and run an SR-MPLS core with TI-LFA, under one support contract.

Every role in the core runs OcNOS-SP

OcNOS-SP runs the PE router at the service edge, the P router in the SR-MPLS core, the peering router at the internet edge and the route reflector. You size each role by hardware and license.

A full-table internet edge in Switzerland and backbones in Austria, Canada and Sierra Leone, all on OcNOS in production.

NWPS Runs dual-stack BGP multihoming for a Swiss hospital on two UfiSpace S9600-72XC routers with OP2 external TCAM, which hold the full internet routing table in hardware. Read the story → Citynet Moved its Austrian backbone from its incumbent routers to OcNOS on Edgecore hardware, citing the industry-standard CLI and the extensive feature set. Read the story → Targo Upgraded its backbone with OcNOS on UfiSpace and Edgecore hardware for BGP routing and edge services, alongside its installed multi-vendor equipment.

Questions about the core and the peering edge.

The PE router joins customer sites to the core: it imposes the transport label and holds the L3VPN and EVPN service state. The P router switches labeled packets between PE routers and holds no customer routes, so it spends its capacity on forwarding and fast reroute. OcNOS-SP runs both roles.
Yes, on a platform with an external TCAM in the forwarding path. NWP Services runs two UfiSpace S9600-72XC routers with OP2 external TCAM and OcNOS-SP, holding the full internet routing table, IPv4 and IPv6, in hardware.
Clients peer only with route reflectors, which pass routes between them, so the core needs no iBGP full mesh. OcNOS-SP supports BGP route reflection and BGP confederations on every OcNOS-SP platform.
Yes. From OcNOS 7.0, OcNOS-SP rejects RPKI-invalid routes at the edge. BGP FlowSpec and RTBH push DDoS filters and blackhole routes to the same edge, and large communities carry your peering policy.
The core runs SR-MPLS with TI-LFA and Flex-Algo, on all 26 OcNOS-SP platforms. OcNOS-SP has initial SRv6 support for L3VPN and EVPN services on 10 of the 26, with more SRv6 capability in development. Check each model in the OcNOS Feature Matrix.
Node by node. LDP and SR interworking with an SR mapping server lets segment routing and LDP forward across one domain, so a new router joins the existing core over standard IS-IS, OSPF and BGP and you convert one role at a time.
