4810 /* BGP Multiprotocol Next Hop Principles
4811 *
4812 * BGP Multiprotocol support is specified over a large variety of
4813 * RFCs for different <AFI, SAFI> pairs, which leaves some theoretical
4814 * pairings undefined (e.g., the Abstract of RFC 4760 contemplates
4815 * supporting the IPX address family) as well as leading to some
4816 * omissions, contradictions, and inconsistencies. However, some general
4817 * principles that apply across (nearly) all extant pairs exist.
4818 *
4819 * 1. Global IPv6 addresses can be followed by a link-local IPv6 address
4820 *
4821 * RFC 2545 specifies in section 3, "Constructing the Next Hop field,"
4822 * that when the next hop address type is IPv6, the address given should
4823 * be in global (or site-local) unicast address scope, and it shall be
4824 * followed by the link-local address if and only if the BGP speaker shares
4825 * a common subnet with the address and the peer the route is being
4826 * advertised to.
4827 *
4828 * The wording implies that this holds for any <AFI, SAFI> pair where
4829 * a IPv6 address is used, and RFCs 5549, 7752, and 8950 demonstrate that
4830 * this explicitly holds for the most common ones, including for VPN-IPv6
4831 * addresses (where the route distinguisher field also appears, see
4832 * RFC 4659). Sometimes the possibility is elided where it is known to
4833 * exist e.g. RFC 7606 7.11 MP_REACH_NLRI "For example, if RFC5549 is in
4834 * use, then the next hop would have to have a length of 4 or 16." Thus
4835 * it is possible that its omission in other RFCs covering new <AFI, SAFI>
4836 * pairs is an oversight.
4837 *
4838 * 2. [VPN-]IPv4 NLRI can have [VPN-]IPv6 Next Hop addresses
4839 *
4840 * RFCs 5549 and 8950 declare that the next hop address may not necessarily
4841 * belong to the address family specified by the AFI, updating RFC 2858,
4842 * specifically addressing the case of IPv6 islands across a IPv4 core
4843 * and vice versa.
4844 *
4845 * IPv4 addresses can easily be mapped into IPv6 addresses, and that
4846 * is the solution for one case, but in the other the Next Hop must be an
4847 * IPv6 (or VPN-IPv6) address even though the NLRI is IPv4.
4848 *
4849 * The wording of RFC 8950 strongly implies that the intent is to allow
4850 * IPv6 Net Hop addresses for any case of IPv4 or VPN-IPv4 NLRI, providing
4851 * a BGP Capability to declare that the BGP speakers supports a different
4852 * Next Hop AFI for <AFI, SAFI> pairs defined without this capability,
4853 * and noting those (like <1, 132>, SAFNUM_ROUTE_TARGET, RFC 4684) that
4854 * consider the possibility from the start.
4855 *
4856 * 3. Next Hop Route Distinguisher (RD) is 0 or omitted
4857 *
4858 * RDs do not have a meaning in the Next Hop network address. However, when
4859 * RFC 2547 introduced the VPN-IPv4 address family, at that point the Next
4860 * Hop address family had to be the same as the NLRI address family, so the
4861 * RD was set to all 0. Later defined <AFI, SAFI> pairs with RDs in their
4862 * NLRI have either used this custom of a 0 RD, or else omitted it and
4863 * only had the IP address in the Next Hop.
