namespace eos

class nexthop_group_mpls_action_impl_t

Default constructor.

nexthop_group_mpls_action_impl_t(mpls_action_t action_type)

Constructs an MPLS action with a specific switching operation.

Getter for ‘autosize’: Dynamic resizing configuration for the nexthop group. When set, unresolved entries from the nexthop group are not programmed into hardware, and packets will be hashed across the remaining reachable entries in the group. Disabled (i.e. set to false) by default.

void autosize_is(bool autosize)

Setter for ‘autosize’.

Utility method to return the number of entries configured in the nexthop group.

std::map< uint16_t, nexthop_group_entry_t > const & nexthops() const

Setter for ‘counters_unshared’.

bool hierarchical_fecs_enabled() const

Getter for ‘hierarchical_fecs_enabled’: Enableing hierarchical fec resolution for programming nexthop group entries. If this flag is true, the entry resolved over a remote nexthop will be programmed hierarchically in the hardware, i.e., the entry is pointing to another FEC which resolves over other nexthops. If the flag is false, the entry resolved over a remote nexthop will be programmed with the final resolved nexthop directly. In case the remote nexthop is resolved over ECMP of nexthops one of the ECMP nexthops is chosen to be programmed for the entry, in order to maintain the size of the nexthop group. This flag is also required to be set to true in order to configure entries resolving over other nexthop groups. The flag is disabled (i.e set to false) by default.

Setter for ‘hierarchical_fecs_enabled’.
