Supported BGP Standards

The Junos OS substantially supports the following RFCs and Internet drafts, which define standards for IP version 4 (IPv4) BGP.

For a list of supported IP version 6 (IPv6) BGP standards, see Supported IPv6 Standards.

Junos BGP supports authentication for protocol exchanges (MD5 authentication).
