If those routers are connected to the internet directly, you can use GRE
tunnels. Just be aware that GRE tunnels are not encrypted. If your router
has an IOS image that supports IPSEC, you may want to apply IPSEC to that
GRE tunnel. I will provide an example of a simple GRE unencrypted tunnel:
Montreal
------------------
Say the internet IP assigned to the router is: 172.16.50.250
interface tunnel 0
ip address 10.0.0.1 255.255.255.252
tunnel source 172.16.50.250
tunnel destination 172.16.60.250
tunnel key 12345678
!
New Jersey
-------------------
Say the internet IP assigned to the router is: 172.16.60.250
interface tunnel 0
ip address 10.0.0.2 255.255.255.252
tunnel source 172.16.60.250
tunnel destination 172.16.50.250
tunnel key 12345678
!
10.0.0.1 and 10.0.0.2 are the private IP addresses you are encapsulating
within the VPN tunnel (choose any address according to your own subnetting
scheme). After you enter that configuration, you should be able ping
10.0.0.2 from Montreal and vice-versa. This should give you your basic
router-router connectivity.
