That looks like some Cisco switches running STP. That 00:0c:cc:cc:cd is the L2 multicast address for spanning tree and the 00:19:30:4a:f0:6d is definitely a Cisco MAC. I would ignore those. Not part of the problem.
Can you ping both the client IP address and the server IP address in question from the BIG IP device? Just want to make sure you have connectivity to hosts before going any farther.
Also, is there a route for the server subnet on the upstream router pointing to the F5 external floating IP address?

Hi Joe,
Yes we do have the reverse route configured for the subnet which is running behind BIG-IP 10.11.27.0/24 in route domain 1 on our upstream Cisco Switch 6509 running HSRP.
ip route 10.11.27.0 255.255.255.0 10.11.29.251 (10.11.29.251 is the floating IP of BIG-IP external internal means 1.3 in route-domain 1)
Yes I can ping both the back-end servers which is 10.11.27.100 & the client IP which is 10.10.94.200 from the BIG-IP from the route domain 1 by the following command.
[root@CIODCGDNF5LTM01:Active:In Sync] config rdsh 1
[root@CIODCGDNF5LTM01:Active:In Sync] config ping 10.11.27.100
