Exit interface selection based on intermediate paths

A system comprising:

• one or more processors;
• and
• at least one computer-readable storage medium having stored thereon instructions which, when executed by the one or more processors, cause the one or more processors to:
• determine at least a first path and a second path for routing a data packet;
• obtain a first plurality of values for at least one network metric, wherein the first plurality of values corresponds to the first path and at least a first backup path associated with the first path;
• obtain a second plurality of values for the at least one network metric, wherein the second plurality of values corresponds to the second path and at least a second backup path associated with the second path;
• and
• select one of the first path or the first backup path for routing the data packet based on a comparison of at least one of the first plurality of values and at least one of the second plurality of values.

A non-transitory computer-readable storage medium having stored thereon instructions which, when executed by one or more processors, cause the one or more processors to:

• determine, at a network edge device, at least a first path and a second path for routing a data packet;
• obtain a first plurality of values for at least one network metric, wherein the first plurality of values corresponds to the first path and at least a first backup path associated with the first path;
• obtain a second plurality of values for the at least one network metric, wherein the second plurality of values corresponds to the second path and at least a second backup path associated with the second path;
• and
• select one of the first path or the first backup path for routing the data packet based on a comparison of at least one of the first plurality of values and at least one of the second plurality of values.
