If you run EIGRP, how do you make sure your voice traffic stays on the voice vlan if it needs routed?
Router A:
f0/1.10 Data van 10.1.10.0/24
f0/1.20 Voice vlan 17.31.20.0/24
f1/1.100 192.168.1.1/29 >>>> connects to other router 192.168.1.2/29
f1.1.200 192.168.1.5/29 >>>> connects to other router 192.168.1.6/29
for data, we set a static route to 192.168.1.2
for voice, we set a static route to 192.168.1.6
If we remove the static routes, how to set EIGRP so our data vlan routes through the intended data route?

You could use outbound distribute lists on both routers to specify the subnets that should be advertised out each link or you could utilize separate EIGRP processes.

Once AS 100 and AS 200 are configured on both R1 and R2 then there will be no issue.

Aha...
so in the above case:
router eigrp 100 (for the data network)
network 192.168.1.1 0.0.0.3
network 10.1.10.0 0.0.0.255
router eigrp 200 (for voice network)
network 192.168.1.5 0.0.0.3
network 172.31.20.0 0.0.0.255
Would that work?

Hi;
There is little bit change in the eigrp AS no.
router eigrp 100 (for the data network)
network 192.168.1.0 0.0.0.3
network 10.1.10.0 0.0.0.255
router eigrp 100 (for voice network)
network 192.168.1.0 0.0.0.3
network 172.31.20.0 0.0.0.255
Please note in Eigrp AS no. should be same if you want your network will be in same Autonomous System and they will exchange the route. If you configure (mistakenly) different AS no b/w 2 routers they will not create neighborship.
The subnet b/w Switch and Data/Voice Router is /29 or /30?
If its /29 then wild card in eigrp - network 192.168.1.0 0.0.0.7
if its /30 then you configure the wild card correctly.
Thanks & Best regards;

This is 2 EIGRP routes to a 2 different interfaces on another router
router eigrp 100 (for the data network) <<<<< goes to 192.168.1.2
network 192.168.1.1 0.0.0.3
network 10.1.10.0 0.0.0.255
router eigrp 200 (for voice network) <<<<< goes to 192.168.1.6
network 192.168.1.5 0.0.0.3
network 172.31.20.0 0.0.0.255

Hi,
Please tell me you want to exchange routes between these 2 routers. If no. Your configuration is correct. If you want then you need to use same AS no. in EIGRP i.e 100 or 200. Otherwise they will not create neighborship and end result R1 will not receive route from R2 & vice versa.
Thanks & Best regards

Hi Willacey;
Why you want to run 2 EIGRP process (AS100 & AS200) on same time. Router will create 2 EIGRP database, neighbor table and etc. which will occupied the memory.
Thanks & Best regards;

I want to keep data & voice on seperate vlans and route them accordingly. My first post had a typo with a /29 instead of a /30 but the data needs to route via 192.168.1.2/30 and the voice needs to route through 192.168.1.6/30

Hi Louis;
If you run 2 different AS no. of EIGRP (AS 100 & AS 200), then you Data network will not communicate with your Voice network. If you don’t want the exchange the Voice & Data network route each other than your configuration is right. If you want Voice and Data network will exchange the route each other than you need to run a Same AS no. on both Router.
Thanks & Best regards;
