NSX Advanced Load Balancer 使用 Quagga 对虚拟服务进行基于 BGP 的缩放。因此，只有在登录到服务引擎的 Quagga 实例时，才能调试或检查 BGP 配置或 BGP 对等体状态。
有关更多信息，请参见如何使用 VMware NSX Advanced Load Balancer CLI 访问和使用 Quagga Shell。
为了使调试变得更容易，您可以从 NSX Advanced Load Balancer 控制器 Shell 中查看这些命令。
使用控制器查看 BGP/BFD 配置
使用您的凭据登录到控制器 Shell，并查看所需的 BGP/BFD 命令，如下所述：

向对等体通告的路由是使用 vrf_ref 显示的。
注：
可以使用 show serviceengine <se_name> bgp advertised_routes filter vrf_ref <vrf_name> peer_ipv4 <peer_IP> 通过对等体筛选器查看为特定对等体通告的路由。
