i used fib_table_entry_path_add2 function for adding entry to ipv4 fib but in some nodes it discards mpls labels. discard sample:------------------------------------------- ipv4-VRF:0, fib_index:0, flow hash:[src dst sport dport proto ] locks:[src:plugin-hi:2, src:adjacency:1, src:default-route:1, ]1.1.1.0/24 fib:0 index:32 locks:2 src:API refs:1 src-flags:added,contributing,active, path-list:[50] locks:20 flags:shared, uPRF-list:49 len:1 itfs:[2, ] path:[54] pl-index:50 ip4 weight=1 pref=0 attached-nexthop: oper-flags:resolved, 200.2.3.2 host-eth1 [@0]: ipv4 via 200.2.3.2 host-eth1: mtu:9000 02feaa73323f02fe77a26dec0800 Extensions: path:54 labels:[[16 pipe ttl:0 exp:0]] forwarding: unicast-ip4-chain [@0]: dpo-load-balance: [proto:ip4 index:35 buckets:1 uRPF:49 to:[0:0]] [0] [@5]: ipv4 via 200.2.3.2 host-eth1: mtu:9000 02feaa73323f02fe77a26dec0800
