If we receive an IPv6 prefix e.g.: 2001:db8:100::/64 with nextop: 0.0.0.0, and mp_nexthop: fc00::2, we should not treat this with an invalid nexthop because of 0.0.0.0. We MUST check for MP_REACH attribute also and decide later if we have at least one a valid nexthop. Signed-off-by: Donatas Abraitis <[email protected]> (cherry picked from commit a0d2734)
