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 - INTEGER 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 49
