## AI overview

The article compares how Arista EOS, Aruba CX, Cisco IOS, FRRouting, Dell OS10, and Cisco Nexus OS configure BGP community propagation. It highlights differences in command arguments, repeated-command behavior, and support for standard, extended, and large communities.

## Source excerpt

A large number of vendors claim to use industry-standard CLI, which means "something that looks like Cisco IOS, but we can't say that in public." The implementations of that "standard" are full of quirks; as I was making fun of Cisco IOS last week, it's only fair to look at how others deal with BGP community propagation. netlab has BGP configuration templates for 14 different platforms1, including these implementations that look like Cisco IOS from a distance if you squint just right2: Arista EOS, Aruba CX, and FRRouting. You can check the configuration templates if you wish; here's the TC&DB3 overview: Read more ...
