I think I have a simple question. My router is basicly use to establish VPN with remote router. So, I have these line:
ip route 0.0.0.0 0.0.0.0 10.131.56.1
Also, for the users, the default gateway is this router. (10.131.56.4, the hub VPN)
I'm using EIGRP for routing.
So if I want to establish a VPN with a remote router I have to add this route
ip route [ip address remote router] 255.255.255.255 [default ip address provider internet]
With these lines, internet navigation go to 10.131.56.1 (that's perfect) because I don't want that an internet navigation use same internet for my VPN with remote site. For VPN, I'm using the provider attach to the router. That's perfect.
But, what I want to do is I would like to use DMVPN. So, the spoke could change public ip address any time. So, in the hub I would like to use this line:
ip route 0.0.0.0 0.0.0.0 [default ip address provider internet]
not this line
ip route 0.0.0.0 0.0.0.0 10.131.56.1 (for user's internet navigation, like presently)
So, what I have to do (i think) is a route-map.
Everything in 10.131.56.0 use this ip route (ip route 0.0.0.0 0.0.0.0 10.131.56.1)
and for other use ip route 0.0.0.0 0.0.0.0 [default ip address provider internet]
I don't know how to use route-map in this situation. Somebody could help me? Or, any other suggestion?
I tried PBR lines but the problem is I can't communicate to VPN remote site because I'm in 10.131.56.0 range and my next hop is 10.131.56.1. So, for example, I want to communicate to 10.135.50.X and this network is a remote site from VPN connection.
Aaah I'm sorry, my bad, I didn't understand you correctly the first time. You want to use PBR on everything else and route 10.131.56.x according to the normal routing table, right?
In that case, try:
access-list 1 permit 10.131.56.0 0.0.0.255
interface [inbound interface]
ip policy route-map mymap
route-map mymap deny 10
match ip address 1
route-map mymap permit 20
set ip next-hop [default ip address provider internet]
In this scenario, everything in the 10.131.56.x /24 is routed by the normal routing table (is denied by the route-map) and everything else is routed by the route-map to the default ip address of ISP. I hope that I got it right this time.
