Answer Wiki:
You can outbound but you may need some help from your ISP (s) to do the inbound. Easiest way is to set up 2 VLANs and and SVI per VLAN. Put each routers ethernet port into an access port in a VLAN. Configure a /30 on each SVI and the other end on a router. The use 2 default static routes. See below: vlan 1 (configured by default) vlan 2 interface vlan 1 (configured by default) ip address 192.168.1.1 255.255.255.252 no shut ! interface vlan 2 ip address 192.168.2.1 255.255.255.252 no shut ! interface fas0/1 desc Link To ISP A Router 1 switchport mode access switchport access vlan 1 no shut ! interface fas0/1 desc Link To ISP A Router 2 switchport mode access switchport access vlan 2 no shut ! ip route 0.0.0.0 0.0.0.0.0 192.168.1.2 ip route 0.0.0.0 0.0.0.0.0 192.168.2.2 You may have some issues if both routers and connections aren't from the same ISP though and as I mentioned inbound may need some other work with the ISP. Also feel free to change VLAN numbers as appropriate to your unique topology.
