| /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 |
