[FROG] Simple BGP configuration to test

[Jorge Visentini]

Hi all!

I configured the BGP peer to test and the sessions are UP but it does not
propagate the networks. I tried all the options that I know, but it does
not work yet.

I don't know if the error is my installation on Rocky Linux or just my BGP
syntax.
