Segment Routing

I showed how to use MPLS transport tunnel signaling protocols such as LDP and RSVP-TE to establish MPLS transport tunnels to carry Overlay network services such as ePipe, VPLS and VPRN (L3VPN) for Nokia, Cisco and Juniper routers in my earlier articles. RSVP-TE offers Traffic Engineering (TE) capability where the path of an LSP can … Continue reading Segment Routing

BGP EVPN NVO and Data Center Interconnect with Nokia 7750 and Juniper MX – Part 1

In my previous blogs, I showed how to provision MPLS-based network services such as ePipe, VPLS and L3VPN (VPRN), which are common network services offered by carriers all over the world. One would note that the L2 epipe and VPLS, and the L3VPN network services have a very different control plane design. For the layer … Continue reading BGP EVPN NVO and Data Center Interconnect with Nokia 7750 and Juniper MX – Part 1

ISP Peering with BGP Traffic Steering Policy – Nokia 7750 and Cisco XR

Introduction BGP is the glue to interconnect Internet Service Providers (ISPs) all over the world to form the Internet. There are about 15 tier-1 ISPs such as AT&T and Telefonica etc... providing end-to-end Internet traffic transit service for thousands of tier-2 ISPs and large corporations such as Google using the BGP protocol. Among the tier-2 ISPs and … Continue reading ISP Peering with BGP Traffic Steering Policy – Nokia 7750 and Cisco XR

Seamless MPLS – Nokia 7750 and Juniper MX

Since 2000, carriers all over the world have been unifying their multi-silos Wide Area Networks (WAN) comprising ATM, TDM, Frame Relay, and IP etc... into a single QoS-ready MPLS WAN network to take advantages of the MPLS and silicone technology. The new MPLS WAN supports various traffic types with different QoS, traffic engineering, and network … Continue reading Seamless MPLS – Nokia 7750 and Juniper MX

VPRN (L3VPN) Inter-AS Model C – Nokia 7750 and Cisco XR

In my previous article, I showed how to setup VPRN (or L3VPN) among Nokia 7750 and Cisco 7200 routers so that hosts (e.g., PCs) on different IP subnets can communicate over a carrier's shared IP/MPLS network. The control plane of the VPRN PEs uses Multi-Protocol Internal Border Gateway Protocol (MP-iBGP) with vpn-ipv4 and/or vpn-ipv6 address … Continue reading VPRN (L3VPN) Inter-AS Model C – Nokia 7750 and Cisco XR

Residential Broadband TV and IP Multicast – Nokia 7750 and Juniper MX

For anyone who had attended any broadband networking conferences in 2000s, triple-play and MPLS were the buzzwords at that time similar to today's NFV and SDN. Triple-play means carrying video, voice and data traffic on a common network platform such as MPLS to take advantage of its QoS capability to satisfy the bandwidth, latency and jitter requirements of the traffic. … Continue reading Residential Broadband TV and IP Multicast – Nokia 7750 and Juniper MX

MPLS Network Services – Traffic Engineering, Resilience and MTU

In the previous blogs, I showed how to interop among Nokia, Cisco and Juniper routers for different MPLS layers 2 and 3 network services such as ePipe, VPLS and VPRN using GNS3 and EVE-NG network emulators on a PC. The blogs demonstrate the flexibility and cost-effectiveness of network service design and interop¬†using a PC. In … Continue reading MPLS Network Services – Traffic Engineering, Resilience and MTU
