EVPN二类路由无法通过RT引入到另外一个VPN的IPv4路由表中

需求：要把VPN VPN1中的二类路由通过RT泄露到VPN VPN2路由表

尝试用import evpn mac-ip将VPN1的二类转换为ipv4路由，再通过RT泄漏到VPN2，但是ipv4路由没有进入 VPN VPN2中

VPN1 二类路由（import evpn mac-ip）==》VPN1 ipv4路由（RT泄露）==》VPN2路由

通过import evpn mac-ip引入 VRF的2类路由是插入路由，插入路由不再插入其他VRF

类似import ospf、import direct也不能通过RT引入到其他的VRF中

先通过RT将二类路由从VPN1引入到VPN2，再用import evpn mac-ip将二类路由转换为ipv4路由
