EIGRP Routing between two sites

Hi,

We are planing to implement EIGRP between two sites and our internet links and VPN tunnels to other locations terminated in office 1.

now we want to route VPN tunnel traffic and internet traffic through office 1.

could you please let me know  how to route traffic from office 2 to office 1

we are using at present static routes.

please find attached diagram

please find below EIGRP config what we are planing



Configuration:-
 Office1 Core 1:
inter giga 2/8
no switchport
ip address 172.25.1.6 255.255.255.252

Router eigrp 10
no passive-interface GigabitEthernet2/8
network  192.168.0.0 0.0.255.255
network 172.25.1.0 0.0.0.255
network 172.20.0.0 0.0.255.255
no auto-summary


Office1 Core 2:
inter giga 2/8
no switchport
ip address 172.25.1.2 255.255.255.252

Router eigrp 10
no passive-interface GigabitEthernet2/8
network  192.168.0.0 0.0.255.255
network 172.25.1.0 0.0.0.255
network 172.20.0.0 0.0.255.255
no auto-summary


Office 2 Core 1:
inter giga 2/8
no switchport
ip address 172.25.1.1 255.255.255.252

Router eigrp 10
no passive-interface GigabitEthernet2/8
network  172.16.0.0 0.0.255.255
network 172.25.1.0 0.0.0.255
no auto-summary

Office2 Core 2:
inter giga 2/8
no switchport
ip address 172.25.1.5 255.255.255.252


Router eigrp 10
no passive-interface GigabitEthernet2/8
network  172.16.0.0 0.0.255.255
network 172.25.1.0 0.0.0.255
no auto-summary

if i add static routes both ends  like below is that enough

ip route 0.0.0.0 0.0.0.0 172.20.1.10

adding the default route, ip route 0.0.0.0 0.0.0.0 172.20.1.10, will give a the VSS core a default route that will point towards 172.20.1.10.

core1 and core2 will not know about this default route unless propagated by the VSS core. there are a lot of way to do that, one of which is to redistribute the static route into eigrp so as core1 and core2 will have a gateway of last resort.

you could also use the following on one of your routers which will be the gateway:

router eigrp 10
default-information originate

this command will tell all networks advertised into eigrp that this router is the gateway for all unknown networks.

Thanks for your update i will implement and let you know the result
We implemented this yesterday so please let me give points to user
