[ris-int] how to get the next hop from ris raw data

ok, got that, thanks!

But next question is how this applies to IPv4. The bgpdump.c code
features same constructs for AFI_IP and AFI_IP6.

e.g.

  printf("(IPv4 Unicast)\n");
  printf("NEXT_HOP: %s\n",inet_ntoa(attr->mp_info->announce[AFI_IP][SAFI_UNICAST]->nexthop.v4_addr));
  if (attr->mp_info->announce[AFI_IP][SAFI_UNICAST]->nexthop_len==32)
	printf("NEXT_HOP: %s\n",inet_ntoa(attr->mp_info->announce[AFI_IP][SAFI_UNICAST]->nexthop_local.v4_addr));


is it ever possible to get nexthop_len==32 in this case ???
or did the authors of bgpdump.c just liked typing? :)

Cheers,
