This is the request I’m using:
IpAddDelRoute{nextHopSwIfIndex=1, tableId=2, classifyTableIndex=0,
nextHopTableId=0, createVrfIfNeeded=0, isAdd=1, isDrop=0, isUnreach=0,

Hi Neale,
I’ve tested it without Honeycomb, I’ve just created simple jvpp app with
IpAddDelRoute request as stated bellow.
Here is the entry created via jvpp:
vpp# sh ip fib index 2 10.10.2.3/32 detail
ipv4-VRF:2, fib_index:2, flow hash:[src dst sport dport proto ] locks:1
10.10.2.3/32 fib:2 index:40 locks:2

And here is the entry created via CLI:

Hi Marek,
I don’t see anything wrong with the construction of the request.
Can you please show me the HC logs of the message sent and also
sh ip fib index 2 10.10.2.3/32 detail
this API is used a lot in the unit-tests so I have some confidence that works
under normal circumstances
regards,
neale

Hi,
So I was wrong. I haven’t noticed next_hop_n_out_labels is u8…
Neal: any idea why labels are not added?

Hi,
I think it is a bug in the C handler of the ip_add_del_route message.
Byte order for next_hop_n_out_labels is not flipped.
Please check if this fixes the issue:

Subject: [vpp-dev] Set up MPLS via jvpp
Hi all,
I would like to set mpls via java api, but I have some problems with it.
I want to do java calls equal to this
ip route add 10.10.2.3/32 table 1 via 10.10.1.2 host-veth out-label 1003
which creates this entry in show ip fib index 1
10.10.2.3/32
unicast-ip4-chain
[@0]: dpo-load-balance: [proto:ip4 index:27 buckets:1 uRPF:19 to:[0:0]]
[0] [@10]: mpls-label:[1]:[1003:255:0:eos]
[@1]: arp-mpls: via 10.10.1.2 host-veth11
so I create DTO, which sets fields matching parameters in CLI command:
IpAddDelRoute addRoute = new IpAddDelRoute();
addRoute.isAdd = 1;
addRoute.tableId = 2;
final Ipv4Prefix prefix = new Ipv4Prefix((„10.10.2.3/32“);
addRoute.dstAddress =
Ipv4Translator.INSTANCE.ipv4AddressPrefixToArray(prefix);
addRoute.dstAddressLength =
Ipv4Translator.INSTANCE.extractPrefix(prefix);
addRoute.nextHopAddress =
Ipv4Translator.INSTANCE.ipv4AddressNoZoneToArray(„10.10.1.2“);
addRoute.nextHopSwIfIndex = 1;
int[] labels = new int[1];
labels[0] = 1003;
addRoute.nextHopNOutLabels = (byte) labels.length;
addRoute.nextHopOutLabelStack = labels;
api.ipAddDelRoute(addRoute).toCompletableFuture().get()
but show ip fib index 2 shows different result
10.10.2.3/32
unicast-ip4-chain
[@0]: dpo-load-balance: [proto:ip4 index:44 buckets:1 uRPF:44 to:[0:0]]
[0] [@3]: arp-ipv4: via 10.10.1.2 host-veth11
Is it a bug, or am I doing something wrong?
Another question I’d like to ask is whether is it possible to create MPLS
local-label via jvpp. I could’t find local label API in mpls.api file.
Thanks
