LAN Pool cant communicate over L2L VPN on AdvanceSecurity IOS

Hi i have strange issue, when i upgraded my Cisco Router IOS of Advance Security IOS before that all was good on advanceipservices.

IPSEC VPN is up

But No traffic Passing.

Traffic does pass if i make Source IP as loop back on same router A having VPN (Loopback 100) , but traffic dont pass/cannot ping when i try to generate it from my one hope before the router that is my CORE switches by creating loopback on CORE switch.

is this IOS behaving like ASA? do i need to enable some kind of security levels on interfaces? or statefull issue etc? any help would be great

VPN Router A

for understanding

GigabitEthernet0/0.1       10.174.1.4

GigabitEthernet0/0.202     222.125.139.225

Loopback 100 100.100.100.100

ip route 101.101.101.101 255.255.255.255 GigabitEthernet0/0.202

VPN Router B

GigabitEthernet0/0.1       10.110.1.4

GigabitEthernet0/0.202     203.126.123.145

Loopback 101 101.101.101.101

ip route 100.100.100.100 255.255.255.255 GigabitEthernet0/0.202

again: VPN dont have any issue in itself, since when loopback are made on routers they do ping, and when i create same loop back on my core switches it done ( i do proper static routing when i move loopback on core so routing is not issue )

My issues is resvoled by upgrading to advance ip services again.

so its some feature or bug with IOS for sure, since config was untouched
