Hi


I have 10 sites are connect to head office. connectivity are server--Pix--router. Now If all router running dynamic protocol but firewall are connect to the router static router.

now my question is in this scenario server can communicate other site. or for this i need router and pix both need dynamic protocol or redistribute in router..


example: router is 2811 and pix is 501. now if 2811 router run ospf or eigrp then pix 501 can communicate with router ??.

Hello,


I can't really tell what your question is, but the pix doesn't need to run a routing protocol if it default routes to your router ( and the server default routes to it). You would just need some way of making your routing network know about those networks - you could run ospf on the pix and have it done that way, or static route from your router to the pix and then redistribute your static routes into ospf.

I *think* what you are asking is can you run dynamic routing through the PIX.


i.e.


Router--PIX--(internet)--PIX-Router


If this is the case, then you will need to setup an IPSEC VPN tunnel between the two PIX devices. Then create another GRE tunnel between the two Routers, running inside the IPSEC tunnel. Then the routers will see each other as if on a point-2-point connection, over which your routing protocols will communicate happily.

Pc-Pix-Router=============Router--Pix---Pc

As long as the two routers can communicate via broadcast traffic, or through other routers then yes this will work. In fact you could run OSPF dynamic routing thoughout. However the trafic would be unencrypted.


If however the routers are connected to the internet, then you would need to use an exteral routing protocol such as BGP, which is where my knowledge falls down.
