|  | /proc/sys/net/mpls/* Variables: | 
|  |  | 
|  | platform_labels - INTEGER | 
|  | Number of entries in the platform label table.  It is not | 
|  | possible to configure forwarding for label values equal to or | 
|  | greater than the number of platform labels. | 
|  |  | 
|  | A dense utilization of the entries in the platform label table | 
|  | is possible and expected as the platform labels are locally | 
|  | allocated. | 
|  |  | 
|  | If the number of platform label table entries is set to 0 no | 
|  | label will be recognized by the kernel and mpls forwarding | 
|  | will be disabled. | 
|  |  | 
|  | Reducing this value will remove all label routing entries that | 
|  | no longer fit in the table. | 
|  |  | 
|  | Possible values: 0 - 1048575 | 
|  | Default: 0 | 
|  |  | 
|  | ip_ttl_propagate - BOOL | 
|  | Control whether TTL is propagated from the IPv4/IPv6 header to | 
|  | the MPLS header on imposing labels and propagated from the | 
|  | MPLS header to the IPv4/IPv6 header on popping the last label. | 
|  |  | 
|  | If disabled, the MPLS transport network will appear as a | 
|  | single hop to transit traffic. | 
|  |  | 
|  | 0 - disabled / RFC 3443 [Short] Pipe Model | 
|  | 1 - enabled / RFC 3443 Uniform Model (default) | 
|  |  | 
|  | default_ttl - BOOL | 
|  | Default TTL value to use for MPLS packets where it cannot be | 
|  | propagated from an IP header, either because one isn't present | 
|  | or ip_ttl_propagate has been disabled. | 
|  |  | 
|  | Possible values: 1 - 255 | 
|  | Default: 255 | 
|  |  | 
|  | conf/<interface>/input - BOOL | 
|  | Control whether packets can be input on this interface. | 
|  |  | 
|  | If disabled, packets will be discarded without further | 
|  | processing. | 
|  |  | 
|  | 0 - disabled (default) | 
|  | not 0 - enabled |
