Thanks for everyone's efforts to put this together.

 

Although I admit this point may not be relevant for the intended community, note the eBGP Juniper example is likely fine for M/MX/Trio etc but not going to work on things like QFX/EX that often lack features such as matching on "port", instead requiring something like

 

                    }

                    term BGP-Allow-source {

                        from {

                            source-prefix-list {

                                BGP-Peers-v4;

                            }

                            protocol tcp;

                            source-port bgp;

                        }

                        then accept;

                    }

                    term BGP-Allow-dest {

                        from {

                            source-prefix-list {

                                BGP-Peers-v4;

                            }

                            protocol tcp;

                            destination-port bgp;

                        }

                        then accept;

                    }

 

These platforms are often limited in filter programming space and sometimes with even a moderate amount of peers the filtering becomes impossible.

 

I think some Juniper platforms (or perhaps it was older code versions) don't care for mixed v4/v6 in a prefix list so I have deployed something like the following with the requisite changes in the inet and inet6 lo0 filters

 

           prefix-list BGP-Peers-v4 {

                apply-path "protocols bgp group <*> neighbor <*.*.*.*>";

            }

            prefix-list BGP-Peers-v6 {

                apply-path "protocols bgp group <*> neighbor <*:*>";

            }

 

 

  Note this won't account for things like routing-instances or logical-routers, but you can create more prefix lists as needed.

 

    prefix-list BGP-Peers-v6-instances {

        apply-path "routing-instances <*> protocols bgp group <*> neighbor <*:*>";

    }

    prefix-list BGP-Peers-v4-instances {

        apply-path "routing-instances <*> protocols bgp group <*> neighbor <*.*.*.*>";

    }

It’s a public page so anyone can view. 

 

I have edits restricted right now, but could be convinced to open it up to shib if there is interest.

Ok, hows this link look? It should be it’s own space now. Viewable by everyone, but no edit.
