If i increase the bram memory by adding more block rams then i will be able to save whole lwip libraries in block ram but i want to confirm will the lwip libraries work without external memory(means without saving in external memory ).Need to confirm it so that i can proceed further....

You might be able to do so by having multiple LMB BRAM controllers on the same LMB bus. Note that the largest supported size for a 32-bit on-chip BRAM controller on either Virtex-5 or Virtex-6 is 256KB. I am not sure if SDK is abe to partiotion code between multiple controllers. I think LWIP size is about 1MB (not sure).
I haven't done that, but I'm interested in knowing if other people have tried that.
EDIT: Seems like a Xilinx employee has said that you have to have external memory:
