805 router - need ethernet subinterfaces to have IPs & VLANs

nicolelayne

Hi,

I'm accustomed to dealing with much larger routers and I'm hoping that the 805 router is capable of this.

I want to have 2 sub-interfaces (as the router only has one physical interface), and for each to have a different IP address.

The router goes as far as to let me create the interfaces:

interface Ethernet0

no ip address

!

interface Ethernet0.1

description LAN

!

interface Ethernet0.2

description WAN

!

but when I go into any of the sub-interfaces and try to do 'encapsulation dot1q 3' it says unknown command.

Also when I try to just put on an IP address it gives the following error:

805Router(config-subif)#ip address 192.168.8.1 255.255.255.0

% Configuring IP routing on a LAN subinterface is only allowed if that

subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,

or ISL vLAN.

So I'm really stuck here.

Any help/suggestions would be greatly appreciated.

The router currently has on c805-sy6-mw.123-22.bin which is IP Plus.

Hi Friend,

AFAIK 805 router does not support trunking. However, its successor 870 does provide support for VLAN/802.1q Trunking

Yes, was afraid of that.

Thanks.

I also tried adding a secondary IP to the interface, but that didn't work either. :-(
