Cisco 2821 Configuration

Have a Cisco 2821, two ports to the outside (serial port has T-1), using second port for a new Comcast ISP Modem. SIngle LAN port connected to a a switch with 2 VLANS (separate network segments).

From switch VLAN 10.1.1.1 want to go out Comcast ISP
From switchs VLAN2 192.168.1.1 want to go out Verizon ISP

Is it possible to router specific IP segment traffice to a designated outside interface?  I can not find a reference to this.  Thanks.

Yes.
You just need to put default routes in the router for both.  Then make access lists permitting those ranges out the required interface.

Yes. It's called Policy Based Routing (PBR). Below is an example of how to do it.

access-list 1 permit 10.1.1.0 0.0.0.255    ! vlan 1
access-list 2 permit 192.168.1.0 0.0.0.255 ! vlan 2

route-map homer permit 10
 match ip address 1
 set ip next-hop 12.1.2.3 ! Comcast next hop
route-map homer permit 20
 match ip address 2
 set ip next-hop 12.1.2.3 ! Verizon next hop

interface FastEthernet0/0
 ip policy route-map homer
