Cisco 3725 for Internet Connectivity

Hi,

We have en existing Internet connection using our Cisco 3725 router (ISP A). The router does the NAT and here's the existing default route:

S* 0.0.0.0/0 [1/0] via 1.2.3.153

This router has a "16 Port 10BaseT/100BaseTX EtherSwitch".

Now we have a new Internet connection (ISP B). What I did was to configure two ports on the Etherswitch and added route maps:

---

interface FastEthernet1/0

description "ISP B to provider"

no switchport

ip address 4.5.6.66 255.255.255.252

!

interface FastEthernet1/1

description "ISP B to my network"

no switchport

ip address 4.5.7.225 255.255.255.248

ip policy route-map ISPBInternetTraffic

!

access-list 101 permit ip 4.5.7.224 0.0.0.7 any

route-map ISPBInternetTraffic permit 101

match ip address 101

set interface FastEthernet1/0

set ip default next-hop 4.5.6.65

---

What I want to happen is that when the router sees the traffic coming from the public IPs of ISP B (4.5.7.224 /29) it will direct that to go out ISP B on F1/0.

1. Is my configuration correct?

2. Any suggestions, recommendations?

3. Can I do load balancing or load sharing between the two ISPs?

Best,

Tony
