要指示 EVPN 支持,设备必须发送 AFI 25(对于第 2 层 VPN)和 SAFI 70(EVPN 本身的代码)。 有关详细信息,请参阅 RFC 7432 第 20 节。 您可以看到这些数据,包括 BGP OPEN 的wireshark 捕获中的 AFI/SAFI,如下图所示 BGP EVPN会话配置示例 对于此示例,我使用上面图 中的“示例网络”,仅关注两个 EVPN 对...

SRv6 仅是一种数据平面封装,需要一个控制平面。RFC 9252 定义了两种你可以使用的控制平面:EVPN 是常见的选择,但你也可以使用 L3VPN(RFC 4364)。 EVPN 是明显的赢家。EVPN 实现可以使用 MPLS、VXLAN、PBB 或 SRv6 数据平面封装。 我相信还有其他 RFC 描述了其他组合。请在评论中留下指针。 仅需L3 VPN 经过长...
The EVPN ESI all-active function allows multi-homing and all-active VXLAN gateways to be deployed based on RFC standards, effectively improving the reliability on the VXLAN access side. Currently, only some CloudEngine switch models support this function. For details, see "EVPN ESI All-Active ...

VXLAN MP-BGP EVPN spine and leaf架构使用VXLAN封装。原始的第2层帧被封装在一个VXLAN报头中,然后放置在UDP-IP包中,并通过IP网络传输。该设计符合IETF RFC 7348和IETF bess evpn覆盖标准草案。 底层网络 VXLAN MP-BGP EVPN spine and leaf架构使用第3层IP作为底层网络。
EVPN最初在RFC 7432中被定义,EVPN引入控制平面,用于更好的控制MAC地址学习过程。 EVPN的控制平面采用MP-BGP,数据平面支持MPLS LSPs或者IP/GRE tunneling。 EVPN的优势 EVPN颠覆了传统L2 VPN数据面学习的方式,引入控制面学习MAC和IP指导数据转发,实现了转控...
