- /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 - BOOL
- 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
