Another new change is that most common route print requests are processed by the routing process which significantly improves the speed compared to v6.

Monitoring Advertisements

RouterOS v7 by default disables monitoring of the BGP output. This allows to significantly reduce resource usage on setups with large routing tables.

To be able to see output advertisements several steps should be taken:

• enable "output.keep-sent-attributes" in BGP connection configuration
• run "dump-saved-advertisements" from BGP session menu
• view saved output from "/routing/stats/pcap" menu

[admin@arm-bgp] /routing/bgp/connection>  set 0 output.keep-sent-attributes=yes
[admin@arm-bgp] /routing/bgp/session> print

Networks

Lastly, you might notice that the network menu is missing and probably wondering how to advertise your own networks. Now networks are added to the firewall address-list and referenced in the BGP configuration.
Following ROSv6 network configuration:
