[mpls-linux-general] Question about ldp_range (ldp_range.c)

[Kenny <chi...@it...>]

Hi Jim,

When I was tracing ldp-portable, I found something strange.
Why the both min_gen and max_gen of ldp_range are assigned to
LDP_RANGE_DEF_GEN_MIN?

Please see the "case LDP_GENERIC:" in the following code.

Best Regards,
Kenny

ldp_range *ldp_range_create(int32_t label_space, ldp_label_range_type
type)
{
  ldp_range *r = (ldp_range *) ldp_malloc(sizeof(ldp_range));

  if (r) {
    LDP_LIST_INIT(&r->peer_root, ldp_peer);
    LDP_LIST_INIT(&r->if_root, ldp_if);
    LDP_REFCNT_INIT(r, 0);

    r->label_space = label_space;
    r->type = type;
    switch (type) {
      case LDP_GENERIC:
        r->min.gen = LDP_RANGE_DEF_GEN_MIN;
        r->max.gen = LDP_RANGE_DEF_GEN_MIN;
