1	/proc/sys/net/mpls/* Variables:
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
