A Pix will support listening to rip routes {I believe v 2}. And it will
send a default route out using rip.
You can also use BGP through the pix to get routes from an outside
router to an inside router.

Charles,
If you are talking about PIX firewall, it does not have support for
routing
protocols.
But, as far as I know, you have two options to allow routing protocols
through PIX:
1.  configure a static route or default route on the outside interface
and
define a conduit
for a particular routing protocol, for example:
route outside  ip_address  netmask  gateway_ip
conduit permit ospf host sourec_addr host dest_addr
Also, a static NAT pointer, if NAT is involved:
static (inside,outside) outside_ip_address inside_ip_address netmask
mask
2. use IPSec tunneling between routing end-points through PIX, you need
to
config below:
sysopt connection permit-ipsec
And the regular IPSec, ISAKMP configurations you'd need to make IPSec
work.
HTH.

firewall does not support any routing protocol ( only static routes ).
I would like to use either EIGRP, OSPF or even RIP would be fine too.

Which routing protocol are you using?  Which firewall are you using? 
PIX
or
Router with Firewall featureset?
