However, some general * principles that apply across (nearly) all extant pairs exist. * * 1. Global IPv6 addresses can be followed by a link-local IPv6 address * * RFC 2545 specifies in section 3, "Constructing the Next Hop field," * that when the next hop address type is IPv6, the address given should * be in global (or site-local) unicast address scope, and it shall be * followed by the link-local address if and only if the BGP speaker shares * a common subnet with the address and the peer the route is being * advertised to. * * The wording implies that this holds for any pair where * a IPv6 address is used, and RFCs 5549, 7752, and 8950 demonstrate that * this explicitly holds for the most common ones, including for VPN-IPv6 * addresses (where the route distinguisher field also appears, see * RFC 4659). Sometimes the possibility is elided where it is known to * exist e.g. RFC 7606 7.11 MP_REACH_NLRI "For example, if RFC5549 is in * use, then the next hop would have to have a length of 4 or 16." Thus * it is possible that its omission in other RFCs covering new * pairs is an oversight. * * 2. [VPN-]IPv4 NLRI can have [VPN-]IPv6 Next Hop addresses * * RFCs 5549 and 8950 declare that the next hop address may not necessarily * belong to the address family specified by the AFI, updating RFC 2858, * specifically addressing the case of IPv6 islands across a IPv4 core * and vice versa. * * IPv4 addresses can easily be mapped into IPv6 addresses, and that * is the solution for one case, but in the other the Next Hop must be an * IPv6 (or VPN-IPv6) address even though the NLRI is IPv4. * * The wording of RFC 8950 strongly implies that the intent is to allow * IPv6 Net Hop addresses for any case of IPv4 or VPN-IPv4 NLRI, providing * a BGP Capability to declare that the BGP speakers supports a different * Next Hop AFI for pairs defined without this capability, * and noting those (like <1, 132>, SAFNUM_ROUTE_TARGET, RFC 4684) that * consider the possibility from the start. * * 3. Next Hop Route Distinguisher (RD) is 0 or omitted * * RDs do not have a meaning in the Next Hop network address. However, when * RFC 2547 introduced the VPN-IPv4 address family, at that point the Next * Hop address family had to be the same as the NLRI address family, so the * RD was set to all 0. Later defined pairs with RDs in their * NLRI have either used this custom of a 0 RD, or else omitted it and * only had the IP address in the Next Hop. */ ti = proto_tree_add_item(tree, hf_bgp_update_path_attribute_mp_reach_nlri_next_hop, tvb, offset, nhlen + 1, ENC_NA); next_hop_t = proto_item_add_subtree(ti, ett_bgp_mp_nhna); offset += 1; switch (afi) { case AFNUM_INET: switch (safi) { case SAFNUM_UNICAST: /* RFC 8950 */ case SAFNUM_MULCAST: /* RFC 8950 */ case SAFNUM_UNIMULC: /* Deprecated, but as above */ case SAFNUM_MPLS_LABEL: /* RFC 8277 */ case SAFNUM_MCAST_VPN: /* RFC 6514 */ case SAFNUM_ENCAPSULATION: /* RFC 5512, but "never been used" * according to * draft-ietf-idr-tunnel-encaps-22 */ case SAFNUM_ROUTE_TARGET: /* RFC 4684 */ case SAFNUM_BGP_MUP: /* draft-mpmz-bess-mup-safi-00 */ /* IPv4 or IPv6, differentiated by field length, according * to the RFCs cited above.
