| 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 | |
| Alexander Alemayhu | 4e5da36 | 2017-01-02 18:52:24 +0100 | [diff] [blame] | 8 | A dense utilization of the entries in the platform label table |
| 9 | is possible and expected as the platform labels are locally |

| 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 |

| Robert Shearman | 5b441ac | 2017-03-10 20:43:24 +0000 | [diff] [blame] | 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) |

| Robert Shearman | a59166e | 2017-03-10 20:43:25 +0000 | [diff] [blame] | 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 |

| Robert Shearman | 37bde79 | 2015-04-22 11:14:38 +0100 | [diff] [blame] | 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 |
