Thanks a lot Muhammad Shahzad.
ln -s /usr/local/src/kamailio-4.2.0/examples/pcscf/pcscf.cfg kamailio.cfg
My understanding is that kamailio.cfg will just be a file pointing to pcscf.cfg
So the configuration that Kamailio-PCSCF server will get is basically from pcscf.cfg.
I checked pcscf.cfg file, and content is quite less (I have copy/pasted here below).
There is no request/response routing logic etc in pcscf.cfg.
Is that fine or we are missing something.
Kindly clarify.

# Several features can be enabled using '#!define WITH_FEATURE' directives:
#
# *** To run in debug mode:
# - define WITH_DEBUG
#
# *** To enable nat traversal execute:
# - define WITH_NAT
# - define the connection to the RTP-Proxy: RTPPROXY_ADDRESS
#
# *** To force alls calls through the RTP-Proxy
# - this will automagically enable NAT-Traversal
# - define FORCE_RTPRELAY
#
# *** To enable IPv4/IPv6 Translation (RTPProxy)
# - this will automagically enable NAT-Traversal
# - define WITH_RTPIPV4
#
# *** To enable TCP support execute:
# - define WITH_TCP
#
# *** To enable TLS support execute:
# - adjust CFGDIR/tls.cfg as needed
# - define WITH_TLS
# - this will automagically enable TCP
#
# *** To enable XMLRPC support execute:
# - define WITH_XMLRPC
# - this will automagically enable TCP
#
# *** To enable anti-flood detection execute:
# - adjust pike and htable=>ipban settings as needed (default is
# block if more than 16 requests in 2 seconds and ban for 300 seconds)
# - define WITH_ANTIFLOOD
#
# *** To enable the Rx-Interface:
# - Configure Rx-Diameter-Interface in pcscf.xml
# - define WITH_RX
#
# *** To enable a Homer SIP-Capter-Node:
# - define CAPTURE_NODE with a proper address
#
