For example, I will configure unicast RPF (reverse-path forwarding) on Juniper MX204.
RPF allows you to reduce the impact of DOS-type attacks on IPv4 and IPv6 interfaces.

Configuring iBGP on Juniper MX
For example, I will configure Internal BGP on Juniper MX204. Since there are servers with Accel-ppp (ipoe) in the network and you need to balance users between these servers and Juniper, iBGP will transfer user routes with /32 mask from all devices to the main router/routers. iBGP is also needed when there are several links to Uplink providers that are connected to different routers, then you need to configure iBGP between these routers.

For example, I will configure MikroTik CRS212-1G-10S-1S + IN as a switch.
And so, connect to it with a console cable at a speed of 115200.
Initially login admin without password.
Configuring MikroTIk CRS106-1C-5S
For example, I will set up MikroTIk CRS106-1C-5S. This device is a great budget switch that can also work as a router. In my case, it was perfect for an educational institution, there is a combo port on the back wall, which I configured as a WAN and the Internet was connected to it (from GPON ONU with a twisted pair cable), and managed switches were connected to the front 5 SFP ports.

If you look at the password in the Wireless – Security Profiles menu in RouterOS, then it is hidden behind the symbols and can only be changed, so I will show an example of how you can see it.
