<p>3、实验结果</p>
<p>（1）SP与leaf的ospf、pim、bgp evpn邻居正常建立</p>

<p><img src="data/attachment/forum/202504/15/151452e1j1pz1dpx31s3dz.png" alt="" /></p>
<p>（2）server leaf、border leaf的vpc状态正常，其中BL对接的2台FW采用镜像模式，所以有一个聚合组会处于down状态</p>

<p>（3）Server leaf和Border leaf的nve隧道正常建立</p>

<p><img src="data/attachment/forum/202504/15/151452ggmy0fzgmwmx1vwq.png" alt="" /></p>
<p><img src="data/attachment/forum/202504/15/151452fa6wdiwbv4e4b6r7.png" alt="" /></p>
<p>（4）Server leaf可以学习到Border leaf引入的静态路由</p>

<p><img src="data/attachment/forum/202504/15/151452squi7to5x7siumqp.png" alt="" /></p>
<p>（4）Border leaf可以学习到server leaf发布的主机路由10.18.1.10/32、10.18.2.10/32，并通过ospf传递给PE</p>

<p><img src="data/attachment/forum/202504/15/151452by7wxw7y5wdaypya.png" alt="" /></p>
<p>（5）PC1和PC2均可以ping通PE01的环回口，并且tracert路径符合预期</p>
