Segment Routing

I showed how to use MPLS transport tunnel signaling protocols such as LDP and RSVP-TE for establishing LSPs for MPLS network services on Nokia, Cisco and Juniper routers in my earlier blogs. RSVP-TE offers Traffic Engineering (TE) capability where path of each LSP can be manually defined hop-by-hop instead of just following the IGP's shortest path … Continue reading Segment Routing

Residential Broadband TV and IP Multicast – Nokia SR 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 SR 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

MPLS VPLS Interop – Nokia 7750 and Juniper MX on EVE-NG

In the previous blogs, I showed how to interop MPLS ePipe and VPRN network services between Nokia 7750 and Cisco 7200 routers on GNS3 (http://www.gns3.com) on a Windows PC. In this blog, I will show how to config and verify Nokia 7750 and Juniper MX routers for MPLS VPLS (Virtual Private LAN Service) network service interop … Continue reading MPLS VPLS Interop – Nokia 7750 and Juniper MX on EVE-NG

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
