Use STP to create p2p channels

In networks where switches with limited memory resources are used, simple reception can be used.
 3r330. It is based on building p2p communication channels between L3 routers using STP (more precisely RSTP) and disabling MAC address memory on intermediate switches.
 3r330. To reserve communication channels between routers, you can use the appropriate dynamic routing protocols.

 3r330. 1. On routers on two parallel logical links, the appropriate dynamic routing protocols are configured (do not forget to specify the type of link p2p, if necessary;)).

 3r330. 2. On the switches for each of the two parallel p2p-channels (VLAN) is built a netless STP tree. The topology of each VLAN should be built in such a way that in case of failure of any of the network components between the two end routers, the second p2p channel continues to work.

 3r330. 3. On all intermediate switches involved in organizing parallel logical links (using VLAN), you can disable MAC address memorization. This allows you to significantly simplify the requirements for the parameters of intermediate switches when the traffic of a large number of devices with unique MAC addresses passes through them.
