I would like to build a SRv6 network with p4 language and bmv2. In P4-tutorials(https://github.com/p4lang/tutorials) they use mininet while I'm using Proxmox VE to build different virtual machines. I want to use bmv2 as software switches but I failed to load control plane configurations.

I'm using a SRv6 implement on Github(https://github.com/XiaoM1573/p4-tutorial-srv6) and I tried to write a s1-runtime.json to define my own control plane configurations. Here's my s1-runtime.json:

{
    "target":"bmv2",
    "p4info":"build/srv6.p4.p4info.txt",
    "bmv2_json":"build/srv6.json",
    "Table_entries":[
       {
          "table":"ingress.local_mac_table",
          "match":{
             "hdr.ethernet.dst_addr":"22:b8:f2:fd:8a:52"
          },
          "action_name":"NoAction",
          "action_params":{
             
          }
       },
       {
          "table":"ingress.local_sid_table",
          "match":{
             "hdr.ipv6.dst_addr":["1::1","128"]
          },
          "action_name":"ingress.end",
          "action_params":{
             
          }
       },
       {
          "table":"ingress.transit_table",
          "match":{
             "hdr.ipv6.dst_addr":["3::3","128"]
          },
          "action_name":"ingress.insert_segment_list_2",
          "action_params":{
             "s1":"2::2",
             "s2":"4::4"
          }
       },
       {
          "table":"ingress.transit_table",
          "match":{
             "hdr.ipv6.dst_addr":["4::4","128"]
          },
          "action_name":"ingress.insert_segment_list_2",
          "action_params":{
             "s1":"A3:33::33",
             "s2":"3::3"
          }
       },
       {
          "table":"ingress.routing_v6_table",
          "match":{
             "hdr.ipv6.dst_addr":["2::2","128"]
          },
          "action_name":"ingress.set_next_hop",
          "action_params":{
             "dmac":"22:b8:f2:fd:8a:52",
             "port":"1"
          }
       },
       {
          "table":"ingress.routing_v6_table",
          "match":{
             "hdr.ipv6.dst_addr":["2::2","128"]
          },
          "action_name":"ingress.set_next_hop",
          "action_params":{
             "dmac":"22:b8:f2:fd:8a:52",
             "port":"2"
          }
       },
       {
          "table":"ingress.routing_v6_table",
          "match":{
             "hdr.ipv6.dst_addr":["4::4","128"]
          },
          "action_name":"ingress.set_next_hop",
          "action_params":{
             "dmac":"22:b8:f2:fd:8a:52",
             "port":"3"
          }
       }
    ]
 }

I compiled the srv6.p4 with p4c -b bmv2 srv6.p4 -o build and the files look like: tree

I'm tring to use simple_switch command to build the network directly. simple_switch -i 0@ens18 -i 1@ens19 build/srv6.json -- --enable-swap However, I have no idea how to load the s1-runtime.json. I've tried going into runtimeCLI and using load_new_config_files command to load this json, and it seems not working.

If this works correctly, when I ping6 4::4 I should read the packets with a Segment-Routing-Header. However I only get this: My Header now
