Hello Naveed,
Fallback bridging does not work for IPv4 traffic.

Fallback Bridging Configuration Guidelines

A maximum of 31 bridge groups can be configured on the switch.

An interface (an SVI or routed port) can be a member of only one bridge group.

Use a bridge group for each separately bridged (topologically distinct) network connected to the switch.

All protocols except IP (Version 4 and Version 6), Address Resolution Protocol (ARP), reverse ARP (RARP), LOOPBACK, and Frame Relay ARP are fallback bridged.

Best regards,
Andras

 bridge-group 1
!
bridge 1 protocol vlan-bridge
!
int fa0/2
no sw
bridge-group 1
!
Rack1R2(config)#int e0/0
Rack1R2(config-if)#ip add 2.2.10.2 255.255.255.0

Rack1SW1#sh bridge
Br Group Mac Address State Type Ports
-------- ----------- ----- ---- -----
   1 0007.856c.48c0 Forward DYNAMIC Fa0/2
-----------------------------------------------------------------------------
