ARoutetype5EVPNroutecarryinganIPv4prefixisrepresentedbya/224prefix,why

为什么5类EVPN IPV4路由的掩码是224位的?这224bits是有哪些字段组成?

比如2类EVPN IPV4路由是216位,

由216 - Length of the MAC VRF NLRI in bits: RD (8 octets) + MAC address (6 octets)

+ L2VNI Id (3 octets) + ESI (10 octets) = 27 octets = 216 bits.

掩码应该不止224吧?

Type5路由传递0~32/0~128掩码长度的网段路由

Type5 路由的报文格式

Type2路由只传递32(IPv4)/128(IPv6)位的主机路由

Type2 路由的报文格式
