Hi there!

First time posting on a mail board - all very new to me!!  I'm just having a 
couple of issues getting started - I've spun up a VPP instance and got my 
Mellanox card added via the RDMA driver (and set to state: up).  I start by 
assigning it an IPv6 address, then I add the following routes:

ip route add <gateway-ip>/128 via <my-ip>
ip route add ::/0 via <gateway-ip>

This seems to get IPv6 connectivity off the ground, but most pings are 
suspiciously fast.  However, it appears to ping public IPv6 addresses just fine 
so I'm hopeful.

Next, I add an IPv4 address with:

set interface ip address <my-rdma-interface> <my-ipv4>/29

Great - sh int addr shows both addresses.  However, when I do the following:

ip route add <ipv4-gateway>/32 via <my-ipv4>

and try to ping said gateway, it just blackholes the packets (as shown by sh 
err and running a trace).  I'm sure what I'm doing wrong is embarrassingly 
trivial, but nonetheless, I'm stumped.  If anyone knows what I could do to 
solve this trivial but critical dilemma, I would be incredibly grateful!

All the very best everyone
