Networking · Routing & MPLS
A full MPLS provider edge, on the subscriber gateway.
Netavo BNG runs BGP with VPNv4 and VPNv6 address families, IS-IS, and MPLS L3VPN with per-service VRFs — a complete PE role on the same system that terminates your subscribers. No adjacent router, no default-route dependency.
The BNG participates in your core as a first-class provider-edge device. It peers iBGP with your route reflectors carrying VPNv4 and VPNv6, and can hold full or partial Internet tables over eBGP where the design calls for it.
Subscribers land directly in the routing domain they belong to. Retail Internet, wholesale voice, walled garden and management each live in their own VRF, each with its own routing policy — on one system.
iBGP to the core route reflectors with VPNv4/VPNv6; full-table eBGP where required.
Per-neighbour state, address families and route counts — the view your NOC works from.
Both VPN address families are first-class: dual-stack subscriber services ride the same L3VPNs as the rest of your network, with IPv6 routes carried natively as VPNv6 — not tunnelled or approximated.
Per-peer policy, route reflection client operation and per-VRF import/export targets behave the way your existing PE estate does, so the BNG drops into an established MPLS design without special-casing.
IS-IS carries the underlay for IPv4 and IPv6, with LDP label distribution and equal-cost multipath forwarding using flow-consistent hashing — subscriber flows never reorder across parallel core links.
Label operations run in the data plane at forwarding rate: transport and VPN label push on ingress, penultimate-hop and double-label pop on egress.
Level-2 adjacencies to the core, dual-topology, with ECMP across both uplinks.
A VPN route as the data plane forwards it — label stack, next-hop and ECMP state in one view.
Wholesale hand-offs are where this matters most: terminate L2TP or PPPoE subscribers and place them straight into the correct customer or service VPN, with the voice VRF, the walled garden and the management plane kept strictly apart.
