Re: ASR1002 VLAN

I have never seen VLANs configured on an ASR1k (its a router, not a switch)

You can do something cryptic and horrible like trying to use bridged virtual interfaces (BVI 123) and use bridge-domains on your ethernet ports to simulate ethernet switching...

Or you could use ethernet subinterfaces on your port facing the switches:
int gig0/0/0.101
encap dot1q 101
ip address 10.101.0.1 255.255.255.0
int gig0/0/0.102
encap dot1q 102
ip address 10.102.0.1 255.255.255.0
int gig0/0/0.N
encap dot1q N
ip address 10.N.0.1 255.255.255.0
etc...

I was able to setup VLANs with my 3945 ISR as a router. Basically, I am needing the multiple interfaces on the ASR1002 to share the same gateway. I don't think I can do this without a VLAN...or can I?

I might also add that I would prefer to NOT have to add a switch. The ASR1002 has multiple available interfaces that I would like to utilize. Many of these interfaces need to share the same gateway.

The ASR1000 gigabitethernet interfaces are not switch ports, they are routed ports. You have the wrong platform if that is your intent.

The ISRg2 to my knowledge supports switchports as it supports ethernet switch modules. I do not know enough to speak to the limitations of that platform however.
