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

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

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

In one of my previous blogs, 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 (https://clcnetwork.wordpress.com/2017/03/23/nokia-7750-and-cisco-7200-interop-mpls-vprn-on-gns3/). The control plane of the VPRN PEs uses Multi-Protocol Internal Border Gateway Protocol (MP-iBGP) with vpn-ipv4 … Continue reading VPRN (L3VPN) Inter-AS Model C – Nokia SR and Cisco XR

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
