bridge fdb vxlan nolearning

 

 

 

现在把vxlan类型改为：

10.10.18.213节点上

ip link add vxlan10 type vxlan id 10 local 10.10.18.213 dstport 4789 nolearning

10.10.18.214节点上

ip link add vxlan10 type vxlan id 10 local 10.10.18.214 dstport 4789 nolearning

[root@evpn2 ~]# bridge fdb show | grep vxlan10

无法ping通
[root@evpn2 ~]# bridge fdb  add  00:00:00:00:00:00 dev vxlan10 dst 10.10.18.213

还是无法ping通
在10.10.18.213节点上添加
[root@evpn2 ~]# bridge fdb  add  00:00:00:00:00:00 dev vxlan10 dst 10.10.18.214

ping 通了

开启nolearning之后10.10.18.213节点后fdb不会学习到这条条目
