appreciate the reply though i'm unsure what the confusion is about, i mean why you have requested config.
i'm assuming that under protocols bgp > group stanza, that 'type-external' refers to eBGP neigbors, and 'internal' for iBGP.
If this = true, then my question is, is the cmd mandatory i.e. internal/external type?.
I ask this since bgp peers can be successfuly created without.
