+Network Layer protocols. BGP supports multiple Address Family
+Identifier (AFI), namely IPv4 and IPv6. Support is also provided for
+multiple sets of per-AFI information via Subsequent Address Family
+Identifiers (SAFI).  In addition to unicast information, VPN information
+@cite{RFC4364} and @cite{RFC4659}, and Encapsulation information
+@cite{RFC5512} is supported.
