Can a ASR 920 route

[MICHAEL J. KUPEC]

We are upgrading to a 1 gig circuit from our ISP 

We currently have two routers in a BGP config giving us 200/100 net speed with a customer provided subnet that's a /24

To go to the 1Gig they installed a ASR 920-24SZ(?) and applied a temp /30 for us to test the circuit.

Last Wednesday evening we went to switch that /30 to the /24 we have from the ISP.  After some work, we find out from the tech at the ISP that we cannot apply the /30 to the ASR as it's not a router! 

We're told that we have to provide our own router to route the /34 subnet to the current /30. 

That doesn't make sense! Both the /30 Subnet AND the /24 Subnet are valid internet facing IP Subnets! 

I thought the ASR 920 was a router. If so, why can't it handle a /24 like a /30?

Just to make clear what I'm asking. 

Current Subnet that's applied to the customer side of the ASR is 4.79.22.162/30

We'd like our 209.x.x.x/24 to be applied to this interface instead of the /30 above. 

Of the 254 IP addresses in that /24 we're currently using about 34. 

Isn't this possible with a ASR to handle all the IP's in that /24?
