网络工程 - EVPN MAC 广告路由未安装到 L2 转发表 - 吾爱随笔录

我有一个基于 VLAN 的 EVPN，它根据第一天：将以太网 VPN 用于数据中心互连一书中描述的网络拓扑连接实验室环境中的两个站点：

出于某种原因，看起来来自远程 PE 的 MAC 通告路由没有安装到mac-table本地 PE 的。例如，存在一种用于MAC地址的路由fe:86:dd:0e:ff:f3在EVPN-1.evpn.0表中：

2:11.11.11.11:1::100::fe:86:dd:0e:ff:f3/304 MAC/IP (1 entry, 1 announced)

我希望fe:86:dd:0e:ff:f3在设置mac-table了标志R（远程 PE MAC）的本地 PE 中看到 MAC 地址，但它不存在：

root@PE21> show evpn mac-table

MAC flags       (S -static MAC, D -dynamic MAC, L -locally learned, C -Control MAC
    O -OVSDB MAC, SE -Statistics enabled, NM -Non configured MAC, R -Remote PE MAC, P -Pinned MAC)

Routing instance : EVPN-1
 Bridging domain : __EVPN-1__, VLAN : 100
   MAC                 MAC      Logical          NH     MAC         active
   address             flags    interface        Index  property    source
   fe:96:dd:0e:ff:f4   D        ae0.100

root@PE21>

本地 PE( PE21) 和远程 PE( PE11)上的 EVPN 配置如下所示：

root@PE21> show configuration routing-instances EVPN-1
instance-type evpn;
vlan-id 100;
interface ae0.100;
routing-interface irb.100;
route-distinguisher 21.21.21.21:1;
vrf-target target:65000:1;
protocols {
    evpn {
        default-gateway do-not-advertise;
    }
}

root@PE21>


root@PE11> show configuration routing-instances EVPN-1
instance-type evpn;
vlan-id 100;
interface ae0.100;
routing-interface irb.100;
route-distinguisher 11.11.11.11:1;
vrf-target target:65000:1;
protocols {
    evpn {
        default-gateway do-not-advertise;
    }
}

root@PE11>

本地CE端口配置如下：

root@CE20> show configuration interfaces ae0
aggregated-ether-options {
    lacp {
        active;
        periodic fast;
    }
}
unit 0 {
    family bridge {
        interface-mode trunk;
        vlan-id-list [ 100 200 201 202 222 ];
    }
}

root@CE20>

什么可能导致这种行为？
