Seamless Multicast Interoperability between EVPN and MVPN PEs
暂无分享,去创建一个
Ethernet Virtual Private Network (EVPN) solution is becoming pervasive
for Network Virtualization Overlay (NVO) services in data center (DC)
networks and as the next generation VPN services in service provider
(SP) networks. As service providers transform their networks in their
COs toward next generation data center with Software Defined
Networking (SDN) based fabric and Network Function Virtualization
(NFV), they want to be able to maintain their offered services
including Multicast VPN (MVPN) service between their existing network
and their new Service Provider Data Center (SPDC) network seamlessly
without the use of gateway devices. They want to have such seamless
interoperability between their new SPDCs and their existing networks
for a) reducing cost, b) having optimum forwarding, and c) reducing
provisioning. This document describes a unified solution based on RFCs
6513 & 6514 for seamless interoperability of Multicast VPN between
EVPN and MVPN PEs. Furthermore, it describes how the proposed solution
can be used as a routed multicast solution in data centers with only
EVPN PEs.
