7 /proc/sys/net/mpls/* Variables:
8 ===============================
10 platform_labels - INTEGER
11 Number of entries in the platform label table. It is not
12 possible to configure forwarding for label values equal to or
13 greater than the number of platform labels.
15 A dense utilization of the entries in the platform label table
16 is possible and expected as the platform labels are locally
19 If the number of platform label table entries is set to 0 no
20 label will be recognized by the kernel and mpls forwarding
23 Reducing this value will remove all label routing entries that
24 no longer fit in the table.
26 Possible values: 0 - 1048575
30 ip_ttl_propagate - BOOL
31 Control whether TTL is propagated from the IPv4/IPv6 header to
32 the MPLS header on imposing labels and propagated from the
33 MPLS header to the IPv4/IPv6 header on popping the last label.
35 If disabled, the MPLS transport network will appear as a
36 single hop to transit traffic.
38 * 0 - disabled / RFC 3443 [Short] Pipe Model
39 * 1 - enabled / RFC 3443 Uniform Model (default)
42 Default TTL value to use for MPLS packets where it cannot be
43 propagated from an IP header, either because one isn't present
44 or ip_ttl_propagate has been disabled.
46 Possible values: 1 - 255
50 conf/<interface>/input - BOOL
51 Control whether packets can be input on this interface.
53 If disabled, packets will be discarded without further
56 * 0 - disabled (default)
