2 VLANs, 3 Routes, How?

[rsabapathee]

Hi,

I have a setup as attached. I have asked the question before but my config (described below)has not worked.

1. The 1841 Router has all the intelligence (ie routing info)

2. The 2 VLANs must use its own ADSL Router. (I understand this ought to be configured as PBR)

3. Both VLANs must connect to network 192.168.10.0 for a common application. (I have tried some access list but no good)

Here is my attempted config:

access-list 1 permit 192.168.1.0 0.0.0.255 any

access-list 2 permit 192.168.2.0 0.0.0.255 any

access-list 100 deny ip any 192.168.10.0 0.0.0.255

route-map ADSL permit 10

match ip address 100

match ip address 1

set ip next-hop 192.168.1.2

route-map ADSL permit 20

match ip address 100

match ip address 2

set ip next-hop 192.168.2.2

int fastethernet 0/0

ip policy route-map ADSL

ip route 192.168.10.0 0.0.0.255 10.0.0.1 (note the ip 10.0.0.1 is the wireless interface between the 2 1841)

Any suggestions?

Hello,

your configuration of PBR has to be changed.

As far as I know, the problem are the ACLs.

First skip ACL 100.

use the following ACLs:

access-list 101 deny 192.168.1.0 0.0.0.255 192.168.10.0 0.0.0.255

access-list 101 permit 192.168.1.0 0.0.0.255 any

access-list 102 deny 192.168.2.0 0.0.0.255 192.168.10.0 0.0.0.255

access-list 102 permit 192.168.2.0 0.0.0.255 any

the route-map becomes

route-map ADSL permit 10

match ip address 101

set ip next-hop 192.168.1.2

route-map ADSL permit 20

match ip address 102

set ip next-hop 192.168.2.2

This should work.

However, the best solution would be to configure a static route for 192.168.10.0/24 on the two ADSL routers and make them the default gateways for VLAN1 and VLan2. So PCs will be redirected via icmp redirect to the 1841 when accessing net 192.168.10.0/24 and will use the ADSL router for everything else.

Hope to help

I understand your point. However the application is actually VoIP and its best to limit the number of routers dealing with this class traffic.

I have all the QoS configured on the 1841 and the ADSL routers are non-QoS enabled devices.
