The version that you are running does indeed support Dot1Q trunking. You didn't specify which router, but the bottom line is that Dot1Q encapsulation is specified on the SUB-INTERFACES, not on the main interface. The main interface holds the IP for the Native VLAN. All the other VLANs need to be configured on the sub-interfaces of the physical port and it is there that the "encapsulation dot1q " command is required.
Here is a document on configuring Dot1Q trunking on 2600s running 12.0(x)T:
Basically, you will configure a subinterface for all the different VLANs.
I.e. If you had 4 VLANs (1, 2, 3,4) coming from a trunk on a switch.. you would configure 3 sub-interfaces for the 3 encapsulated VLANs, and then configure the main physical interface for the Native (non-encapsulated) VLAN. in this example, we'll assume that VLAN 1 is the native VLAN, so we'll assign its subnet to the main interface.
/* The physical interface corresponds to the native VLAN
int fast 0/0
ip address 192.168.1.1 255.255.255.0
/* The first sub-interface is for the first encapsulated VLAN, which is VLAN2 in
In my understanding for IOS 12.0.7 to support encap on ethernet inter. require IP Plus feature set. We have a plan to upgrade for higher version 12.2.(11)T do this can support encap. dot1Q on the interface. ?
I have other 7200 router (7206VXR (NPE400) processor (revision A) with 245760K/16384K bytes of memory - c7200-p-mz.122-11.T1.bin) it does support encap. dot1Q. The IOS feature set still Service Provider feature set. My question is is IOS 12.2(11)T1 IP plus supported. ?
I'm still confused on IOS ver capability.. can somebody point me the url..
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
