MPLS Sysfs variables |
|
==================== |
|

|
/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 - INTEGER |
|
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
