Cisco 3725 Router 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
