Routing on Cisco 892

[christian.blumer]

Hi,

I have a Cisco 892 with 9 GE ports, but I'm unbale to route between port 8 and 9 (nor any other)

Any hint would be greatly apreciated.

Thanks in advance.

Hi Christian,

You'll have to create VLAN's and route between them. The only physical interface that can route is the dedicated WAN interface.

Hope it helps.

Collin makes a very good point. If that does not resolve the issue then perhaps Christian can post the config of the router so that we can see what has been done and perhaps identify what the problem is.

I have an 892 that I use at home for a firewall and I ran into the same "issue".

[christian.blumer]

you mean like this ?

interface GigabitEthernet9

no ip address

duplex auto

speed auto

!

interface GigabitEthernet9.4

encapsulation dot1Q 4

ip address aaa.aaa.aaa.aaa 255.255.255.248

!

and the same for the G8 ?

That would be routing on a stick (which will also work). But I was thinking more like this-

interface gi1

switchport mode access

switchport access vlan 5

int vlan 5

ip add 10.10.10.10 255.0.0.0

Thanks for your help, problem solved.

Here is my final config in this case:

interface GigabitEthernet8

no ip address

duplex auto

speed auto

media-type rj45

!

interface GigabitEthernet8.5

encapsulation dot1Q 5

ip address dhcp

!

interface GigabitEthernet9

no ip address

duplex auto

speed auto

!

interface GigabitEthernet9.4

encapsulation dot1Q 4

ip address aaa.aaa.aaa.aaa 255.255.255.248
