Hi Jeff, There isn’t a way to achieve that using the current CLI. I would suggest you add a new CLI/API for your feature (e.g. jeff-feat label 100 … ) and then if: 1. You want your feature to process then packet and then pass it on to the normal FIB processing, you would ‘interpose’ your feature’s DPO in the existing FIB chain (i.e. your CLI would be in addition to the usual ‘mpls local-label 100 …. via X’). see example: https://github.com/FDio/vpp/blob/master/src/plugins/unittest/fib_test.c#L9824 and your DPO will need to implement the interpose functionality: https://github.com/FDio/vpp/blob/master/src/vnet/dpo/mpls_label_dpo.c#L1239 2. you only want your node to handle the MPLS packets, in which case your feature can directly create the MPLS table entry and provide the DPO to use, e.g.: https://github.com/FDio/vpp/blob/master/src/plugins/unittest/fib_test.c#L9824

For example, if VPP receives an MPLS frame with label 12345: 1) pop label 12345 2) add labels 100 101 102 3) enqueue to my_node Maybe something like the following, but I don't know if "mpls local-label" supports sending to a custom node. I looked at the "via" options in unformat_fib_route_path(), but nothing jumped out. mpls table add 0 mpls local-label add 100 eos via <my_node> out-labels 100 mpls local-label add 100 non-eos via <my_node> out-labels 100 sr mpls policy add bsid 12345 next 100 next 101 next 102 or mpls table add 0 mpls local-label add 12345 eos via <my_node> out-labels 100 101 102 mpls local-label add 12345 non-eos via <my_node> out-labels 100 101 102 Thanks, Jeff
