BGP EVPN and All-Active Multi-Homing Ethernet Segment

BGP MPLS-Based Ethernet VPN or BGP EVPN (RFC 7432) offers more scalable, flexible (e.g., per flow and service load balance) and resilience (e.g., Multi-Home) Overlay layer 2 (L2) and layer 3 (L3) network services than the older TLDP and MP-BGP VPN based L2 and L3 MPLS network services designed in 2000s. BGP EVPN supports the … Continue reading BGP EVPN and All-Active Multi-Homing Ethernet Segment

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

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 VPRN (L3 VPN) Interop – Nokia 7750 and Cisco 7200 on GNS3

In the previous blog, I showed how to interop Nokia 7750 and Cisco 7200 with MPLS ePipe Pseudo Wire service all on a PC running GNS3. RSVP-TE and TLDP are used as the signalling protocols to establish the MPLS Transport and Service Tunnels respectively for the MPLS ePipe service. Since ePipe is a layer 2 network … Continue reading MPLS VPRN (L3 VPN) Interop – Nokia 7750 and Cisco 7200 on GNS3

MPLS Pseudowire ePipe Interop – Nokia 7750 and Cisco 7200 on GNS3

Not long ago, network equipment testing involves a lot of coordination with your colleagues to share and wire up the equipment in the lab before any testing can be started. With the popularity of network virtualization, all major vendors now offer virtualized version of their equipment in one form or another and many simple network equipment testing … Continue reading MPLS Pseudowire ePipe Interop – Nokia 7750 and Cisco 7200 on GNS3
