MSTP(Multiple Spanning Tree Protocol)是一种支持多个 VLAN 的生成树协议,可以在一个网络中同时支持多个 VLAN 的生成树,从而提高网络的可靠性和可扩展性。
VRRP(Virtual Router Redundancy Protocol)是一种实现路由器冗余的协议,可以将多个路由器组成一个虚拟路由器,提供默认网关的冗余功能,从而提高网络的可靠性。
OSPF(Open Shortest Path First)是一种链路状态路由协议,通过计算最短路径来实现路由选择,可以适用于大型复杂网络的路由选择。

MSTP (Multiple Spanning Tree Protocol) is a network protocol that creates a loop-free topology for Ethernet networks.
VRRP (Virtual Router Redundancy Protocol) is a network protocol that provides automatic failover of routers by creating a virtual IP address that is shared by multiple routers.
OSPF (Open Shortest Path First) is a routing protocol that uses link-state routing to determine the shortest path between two points in a network.
DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network.
NAT (Network Address Translation) is a network protocol that translates private IP addresses into public IP addresses to allow devices on a private network to access the internet.

2. 配置MSTP根桥:
[SW1] stp root primary
3. 配置MSTP端口:
[SW1] interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1] stp instance 1 priority 128

[SW1-GigabitEthernet0/0/1] ospf 1 area 0.0.0.1
3. 配置OSPF邻居:
[SW1] interface GigabitEthernet 0/0/1
