Hi vpp-dev team,
I am trying to check the iOAM feature of VPP. Do you have any working config sample for this? I have checked the following url's and the configuration mentioned, was sometimes rejected by the CLI or had no effect. [URL1] https://docs.fd.io/vpp/18.04/ioam_plugin_doc.html [URL2] https://docs.fd.io/vpp/17.04/ioam_ipv6_doc.html I have 3 VPPs 2102:1100::100-->[Encap VPP]---->[Transit VPP]---->[Decap VPP]-->2102:3100::100 ^this is the src host ^this one is the dst host I have the following configuration for Encap Vpp [Encap Vpp] *Want to add iOAM info to all the traffic towards 2102:3100::100 classify table miss-next ip6-node ip6-lookup mask l3 ip6 dst classify session acl-hit-next ip6-node ip6-add-hop-by-hop table-index 0 match l3 ip6 dst 2102:3100::100 set int input acl intfc GigabitEthernet1b/0/0 ip6-table 0 set ioam-trace profile trace-type 0x1f trace-elts 4 trace-tsp 1 node-id 0x1 app-data 0x1234 set ioam rewrite trace Seems like it does encap the info I wanted ====================================== Trace results [Encap Vpp] IP6_HOP_BY_HOP: next index 12 len 72 traced 72 Trace Type 0x1f , 3 elts left [0] ttl 0x0 node id 0x0 ingress 0x0 egress 0x0 ts 0x0 app 0x0 [1] ttl 0x0 node id 0x0 ingress 0x0 egress 0x0 ts 0x0 app 0x0 [2] ttl 0x0 node id 0x0 ingress 0x0 egress 0x0 ts 0x0 app 0x0 [3] ttl 0x40 node id 0x1 ingress 0x3 egress 0x1 ts 0x5efba500 <---- I think this one is working fine app 0x1234 The problem I am facing is, configuration for VPP 18.04 as mentioned in the URL "set ioam rewrite trace-type 0x1f trace-elts 4 trace-tsp 1 node-id 0x1 app-data 0x1234" Is being rejected by the cli, so I have changed it as mentioned above. vpp# set ioam rewrite trace-type 0x1f trace-elts 4 trace-tsp 1 node-id 0x1 app-data 0x1234 unknown input `-type 0x1f trace-elts 4 trace-...' There are some other problems also, like “node” is also rejected by cli, so I used ip6-node and this one works vpp# classify table miss-next node ip6-lookup mask l3 ip6 dst classify table: Mask required vpp# classify table miss-next ip6-node ip6-lookup mask l3 ip6 dst vpp# And url also showing that this config is required for transit and decap VPP also. So do any one have any working configuration for iOAM? Regards, Hadi
