Hi Xyxue, Yes, that’s correct. Note the ip4-lookup-in-table-1 implies a VRF lookup.

You mean that I can configure "mpls local-label add eos 33 ip4-lookup-in-table 1"to pop the inner label,and use "mpls local-label add non-eos 34 mpls-lookup-in-table 0" to pop the outer label. Am I right?

The path (i.e. the config after the ‘via’ keyword) describes whether a new label should be pushed, so the absence of an out-label keyword there means that the router will be seen to pop the label. These configs then; 1) mpls local-label 33 ip4-lookup-in-table 0 removes label 33 and does an IP lookup in Table-ID 0 2) mpls local-label 33 via 2.1.1.2 host-eth0 remove label 33, does not add another, and forwards to 2.1.1.1 on host-eth0 (this is probably what you want) 3) mpls local-label 33 via 2.1.1.2 host-eth0 out-label 66 removes label 33, then adds 66 and forwards via 2.1.1.2 on host-eth0 If you add all three statements, then that’s ECMP. The hash algorithm for MPLS uses only the packets MPLS label, which is always 33, so it’ll only every take one of these choices.
