/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
