## Caveats
### Arista EOS
For whatever reason, the tested version of Arista EOS does not supply certain details about routes in its JSON output when running commands `show ip bgp regex ` or `show ip bgp community `. Specifically, the the route's timestamp and any attached communities are not supplied. When these commands are used with Arista EOS, hyperglass sets the timestamp to the current time, and the community to an empty list.
