Hello, i have RAS5300 connected to a 3845 router.
RAS5300 faste0 ip 10.10.10.2
3845 gigabite0 ip 10.10.10.1
when i am on console of the RAS5300, i can ping 10.10.10.1, but when i dialin to the RAS, i get ip address from the pool RAS, say 10.10.12.10, i try from CMD to ping 10.10.10.1, but i fail, i can ping 10.10.10.2 no problem.
thanks for any help:

To advertise 10.10.12.0 to the 3845 you would need to have a route to advertise and you would need to configure a dynamic routing protocol. The details of how to do that would vary somewhat depending on which routing protocol you use. I will illustrate with EIGRP.
First you would need to have a route to advertise. You can do this by putting the subnet on an interface and including that interface into the routing protocol or you could configure a static route and redistribute the static route into the routing protocol. I will illustrate putting the subnet on an interface.
interface loopback 0
ip address 10.10.12.1 2555.255.255.0
Then you need to configure the routing protocol and include the interfaces (the interface to establish the neighbor relationship and the interface to advertise the address range).
router eigrp 100
network 10.10.10.0 0.0.0.255
network 10.10.12.0 0.0.0.255
Since the ppp negotiation will create individual /32 host routes I would also suggest that you configure a summary address on the LAN interface.
interface fastethernet 0
ip summary-address eigrp 100 10.10.12.0 255.255.255.0
You would also need to configure EIGRP routing on the 3845 and include the 10.10.10.1 interface into EIGRP. And if you do that it is liekly that the 3845 will advertise routes to you so that you do not need the static default route configured.

Hi ,
change ip route 0.0.0.0 0.0.0.0 10.10.10.1
to ip route 0.0.0.0 0.0.0.0 dia 1.
What is the purpose on nat which is applied on Group-Async1 ? Have you defined nat pool for that one..
Thanks,
satish

Hello & thanks for your quick response.
actually i will take the nat from group-async1 because no purpose.
but i would like to ask why woudnt the route to 10.10.10.1 work?
and what will the route to dia 1 would do?
thank you.

Hi ,
I think fastethernet of RAS is conected to gig interface of router.
If you traceroute to 10.10.10.1 is it dropping at 10.10.10.2 ..
add dialer-list 1 protocol ip permit command in global config for interesting traffic.
Thanks,

While satish second suggestion is much better than his first (sending the default route out the dialer rather than out the FastEthernet is almost certainly not what your environment needs) and without a dialer list the dialer will not work. I am confident that the problem is not on your 5300. If you check I believe that you will find that the 3845 does not have a route to 10.10.12.0. You can fix the problem by having the 5300 advertise the 10.10.12.0 network to the 3845 or you can fix the problem by configuring a static route on the 3845 for 10.10.12.0 pointing to the 5300.
As a separate item I am puzzled by this line on your group async:
ppp authentication chap DIAL-UP
This names an authentication method called DIAL-UP which would make sense if you were using aaa authentication for dial in users. But the 5300 is configured with no aaa new-model. Can you clarify what is happening here?

hello,
thanks for your ideas.
id rather advertise the 10.10.12.0 network to the 3845. can you help me with command for advertising a network to next hob?
the DIAL-UP i had it there because i am not yet finished with the setup of radius, so i will be using it later on, no puzzle :)
