1/proc/sys/net/mpls/* Variables:
 2
 3platform_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
22ip_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
33default_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
41conf/<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
