For the data plane VxLAN tunnel vGMUX–vGW, the IP address and VNI settings in vGW are inconsistant, breaking the data plane reachability.

In the current SB04 situation:

vGMUX facing vGW

"v3po:vxlan": {
"vni": 105,
"src": "10.5.0.21",
"dst": "10.5.0.105",
"encap-vrf-id": 0
},

vGW:

"v3po:vxlan": {
"vni": 100,
"src": "10.5.0.100",
"decap-next": "v3po:l2-input",
"dst": "10.5.0.21",
"encap-vrf-id": 0
},

I checked IPV4_ADDRESS_POOL and VLAN_ID_POOL in the SDNC DB and found that SDNC assigned 10.5.0.105 to vGW and 105 to the VNI. It did use the correct values for vGMUX VxLAN config. But when instantiating vGW, it used the wrong values. Please check the corresponding DG. Thanks.
