NXOS - Traffic redirection to another next-hop - Tunnel interface

[leodlsrt]

Hi,
I want to make a GRE Tunnel to another site to establish a BGP session with an another ASN, on Cisco Nexus 9396PX.

I have create a tunnel interface in my default VRF (EBGP are running on), but the traffic going on to my first default route.

Actually my configuration :

feature pbr
ip route 0.0.0.0/0 100.23.1.90
ip route 0.0.0.0/0 10.10.20.10 2 

ip prefix-list PFX-AS1234-CUST-V4 seq 10 permit 1.2.3.0/24
ip prefix-list PFX-AS1234-CUST-V4 seq 11 permit 4.5.6.0/24 
ip prefix-list PFX-AS1234-CUST-V4 seq 95 deny 0.0.0.0/0 ge 32 
ip prefix-list PFX-AS1234-CUST-V4 seq 100 deny 0.0.0.0/0 le 32 
route-map RPL-AS1234-CUST-IN-V4 permit 100
route-map RPL-AS1234-CUST-OUT-V4 permit 100
  match ip address prefix-list PFX-AS1234-CUST-V4 

interface Tunnel100
  ip address 100.30.2.1/30
  tunnel source 37.XXX.XXX.XXX
  tunnel destination 193.XXX.XXX.XXX
  no shutdown

router bgp MY_ASN_NUMBER
  template peer TP-AS1234-CUST-V4
    remote-as 1234
    remove-private-as
    address-family ipv4 unicast
      send-community
      route-map RPL-AS1234-CUST-IN-V4 in
      route-map RPL-AS1234-CUST-OUT-V4 out
      maximum-prefix 5
      default-originate
      soft-reconfiguration inbound

  neighbor 100.30.2.2
    inherit peer TP-AS1234-CUST-V4
    no shutdown

I've tried this configuration using VRF but it seems that not worked, the BGP session broke.

vrf context test-sym
  ip route 0.0.0.0/0 10.10.20.10 vrf default
  ip route 193.XXX.XXX.XXX/32 100.23.1.90 vrf default

interface Tunnel100
  vrf member test-sym
  ip address 100.30.2.1/30
  tunnel source 37.XXX.XXX.XXX
  tunnel destination 193.XXX.XXX.XXX
  no shutdown

How can i set the next hop to 10.10.20.10 for the traffic coming only from this tunnel?

ip policy route-map doesn't exist on interface type tunnel on my side (feature PBR is enabled)

Thanks,
