Not sure what is wrong, this works for me:
DBGvpp# loop create-interface
loop0

Yes.
An easy way to do it is to use the ip_session_redirect

Yes.
An easy way to do it is to use the ip_session_redirect plugin (not merged):
https://gerrit.fd.io/r/c/vpp/+/33455
Otherwise, you can do it with current VPP by creating 2 VRFs,
I added two routes like this
vppctl ip route add 192.168.21.0/24 via ipip0
vppctl ip route add 192.168.21.0/24 via ipip1
Can VPP use classify to direct UDP packets to port 2156 using ipip0, UDP packet
to port 2157 using ipip1?
