Hi Neale,
Thank you for your reply. I was offline for sometime and could not track it.
We are using VL APIs to program into vpp and I see some error while programming
mpls route into default mpls table:
Params we pass are as below:
mp->_vl_msg_id = htons (VL_API_MPLS_ROUTE_ADD_DEL);
You are configuring it incorrectly. Please re-read the emails I have already
sent you.

Hi Neale,
I tried all combinations of bind (vppctl mpls local-label

Hi Neale,
So, you suggest bind over other way.
Then, I need to do following for bind of a prefix?
vppctl ip route add table 2 1.1.1.1/32 via 107.243.21.116
VirtualFuncEthernet0/9/0.1800 out-labels 18

Just a small Q:
without bind API, label to prefix, I could manage to make this working.
I just wanted to know what is the real value of bind API?
Is it that bind will just help us to get label and

Hi Neale,
Thank you for the help. We are trying to exercise vpp mpls vpn and we are
preferring label per prefix only. Anyway I am fine even with per VRF label but
adding more local labels which seems fine while adding.
I am trying to evaluate VRF with non-default ip fib tables.

Hi Neale,
Because of this label bind to prefix crash issue, I can think of using label
per VRF and use pop rule as below:
I will add all local labels to same VRF

vppctl mpls local-label 18 eos via ip4-lookup-in-table 1

Hi Neale,
I am not able to test bind CLI along with pop rules. I am seeing vpp crash for

Hi Neale,
ping is fine with per vrf label schema.
But, Issue is with label per prefix. I see 20.05 vpp is crashing as below:

Then, mpls table ID we give for mpls commands always represents ip table id?
for example: mpls local-label 100 del 10.10.20.0/24 table 3 ==> here table is
