Hello,
I'm attempting to configure a Cisco 1812 to interface between 3 distinct subnets (e.g. 10.1.x.x, 10.2.x.x, 10.3.x.x). I'm very new at this, and am trying to learn (without having a device in front of me, to play with!)
Two of the subnets will interface through the two WAN ports (I don't need them for any WAN connections). The following is my configuration commands for one of them:
> enable
<enter password at prompt>
# config
(config)# interface FastEthernet0/0
(config-if)# ip address 10.1.1.1 255.255.255.0
(config-if)# no shutdown
The other WAN inteface would be the same, excepting that I'm using the interface FastEthernet1/0 with the IP address 10.2.1.1.
The switch port I configure as follows:
> enable
<enter password at prompt>
# vlan database
(vlan)# vlan 1
(vlan)# exit
# config
(config)# interface Vlan1
(config-if)# ip address 10.3.1.1 255.255.255.0
(config-if)# no shutdown
Also, I'll configure FastEthernet0/0 as my default gateway, but I'll leave that part out of this post.
As far as communications between the three subnets, through the three configured interfaces, does this above configuration look valid?
Am I missing anything? Most particularly, I feel like I'm missing something in regards to configuring the SVI interface on the 8-port switch.
Thank you very much for your time, and thank you in advance for your help.
