网络工程 - LDP VPLS - 网桥组和网桥域内的数据包行为 - 吾爱随笔录

我有一对 ASR9k，我计划迁移到瞻博网络 MX960。下面是部分配置：

l2vpn
 bridge group VPLS_1
  bridge-domain 101
   interface TenGigE0/2/0/0.101
   !
   vfi 101
    neighbor 1.1.1.1 pw-id 101
    !
   !
   routed interface BVI101
  !
  bridge-domain 202
   interface TenGigE0/2/0/0.202
   !
   neighbor 3.3.3.3 pw-id 3003
    pw-class ro-7450c-1
   !
   neighbor 3.3.3.4 pw-id 3003
    pw-class ws-7450a-2
   !
   vfi 202
    neighbor 2.2.2.2 pw-id 202
    !
   !
   routed interface BVI202
  !
  bridge-domain 11
   interface TenGigE0/1/0/6.11
   !
   interface TenGigE0/2/0/0.11
   !
   vfi 11
    neighbor 11.11.11.11 pw-id 11
    !
   !
  !

我感到困惑的是bridge-domain单个内部的多个实例bridge-group（我确实有多个bridge-groups未显示。）

什么用途各bridge-domain服务而内单bridge-group？这是否违反了 VPLS 的水平分割规则？我不能在 JUNOS 中创建多个 VPLS 实例吗？

如果有人需要澄清，请告诉我。

The Bridge Group (BG) is a non-functional configuration hierarchy that ties several BDs together in part of the same functional group. It functions just as the creation of multiple individual groups with their domains does, as opposed to one group with multiple domains.
