Hi,
Here is what i know, and what i've been able to find:
I don't think there is automatic grouping of neighbor in junos, you have
to make the groups by yourself, example:
> show configuration protocols bgp
group external-peers {
type external;
export bgp_public_out;
peer-as ...;
neighbor ....;
neighbor ....;
}
group internal-peers {
type internal;
export ibgp_export;
neighbor ...;
neighbor ...;
neighbor ...;
}
As for the advertisement interval, the junos term seem to be "out-delay"
and default to 0, but you can set it to the value you like
in each of your group
http://www.juniper.net/techpubs/en_US/junos13.2/topics/reference/configuration-statement/out-delay-edit-protocols-bgp.html
As for the output of a very simple bgp router:
> show bgp group
Group Type: External Local AS: 65530
