   2
   3 platform_labels - INTEGER
   4         Number of entries in the platform label table.  It is not
   5         possible to configure forwarding for label values equal to or
   6         greater than the number of platform labels.
   7
   8         A dense utilization of the entries in the platform label table
   9         is possible and expected as the platform labels are locally
  10         allocated.
  11
  12         If the number of platform label table entries is set to 0 no
  13         label will be recognized by the kernel and mpls forwarding
  14         will be disabled.
  15
  16         Reducing this value will remove all label routing entries that
  17         no longer fit in the table.
  18
  19         Possible values: 0 - 1048575
  20         Default: 0
  21
  22 ip_ttl_propagate - BOOL
  23         Control whether TTL is propagated from the IPv4/IPv6 header to
  24         the MPLS header on imposing labels and propagated from the
  25         MPLS header to the IPv4/IPv6 header on popping the last label.
  26
  27         If disabled, the MPLS transport network will appear as a
  28         single hop to transit traffic.
  29
  30         0 - disabled / RFC 3443 [Short] Pipe Model
  31         1 - enabled / RFC 3443 Uniform Model (default)
  32
  33 default_ttl - BOOL
  34         Default TTL value to use for MPLS packets where it cannot be
  35         propagated from an IP header, either because one isn't present
  36         or ip_ttl_propagate has been disabled.
  37
  38         Possible values: 1 - 255
  39         Default: 255
  40
  41 conf/<interface>/input - BOOL
  42         Control whether packets can be input on this interface.
  43
  44         If disabled, packets will be discarded without further
  45         processing.
  46
  47         0 - disabled (default)
  48         not 0 - enabled
