BGP protocol dissector contain comments
/*
* RFC 2545 specifies that there may be more than one
* address in the MP_REACH_NLRI attribute in section
* 3, "Constructing the Next Hop field".
*
* Yes, RFC 2858 says you can't do that, and, yes, RFC
* 2858 obsoletes RFC 2283, which says you can do that,
* but that doesn't mean we shouldn't dissect packets
* that conform to RFC 2283 but not RFC 2858, as some
* device on the network might implement the 2283-style
* BGP extensions rather than RFC 2858-style extensions.
*/
This is true, see rfc4760 (chapter 11). It is possible to update code in next
releases of Wireshark?
