Hi,
This is smply a routing issue.
ping vrf ABC 192.10.2.2 <-- Using this command your source IP will be the IP of exit interface throught which the route for
host is learned (in your case 192.10.2.2)
If you are learning the route for 192.10.2.2 from interface e0/0 and the ip of interaface e0/0 is 1.1.1.1
ping vrf ABC 192.10.2.2 = ping vrf ABC 192.10.2.2 source 1.1.1.1
In your case you dont have proper routing between 192.10.2.2 & 1.1.1.1
