ESI
ESI 主要用来标识CE， 相同CE使用一样的ESI.
EVPN技术为PE与某一CE的连接定义唯一的标识ESI（Ethernet Segment Identifier），连接同一CE的多个PE上的ESI值是相同，连接不同CE的ESI值不同。PE之间进行路由传播时，路由中会携带ESI值使PE间可以感知到连接同一CE的其他PE设备。
ESI共10字节， 1字节的type， 9字节vlaue。
配置案例：
RP/0/RSP0/CPU0:9001-2-PE4#show run evpn
Thu Mar 11 07:36:12.984 UTC
evpn
interface Bundle-Ether100
ethernet-segment
identifier type 0 11.11.11.11.11.11.11.11.11 <<<<<MHD 多个PE上要配置相同的ESI，RT也需要配置一样（RT-4 通告用来发现MHD的peer PE， RT用来限制导入）
