Configuring a simple www connection VRRP backup router

[m.x]

Hi,

I have to do a test on a new line, faster, on a Cisco ASR-920-12CZ-A with uses VRRP and has a antiDDoS configuration. 

What I want to achieve sounds simple to me, place a public IP on the interface, say Gi0/0/3 and set the GW of last resort to this interface. It sounds so simple, that i don't trust the sulution:

interface GigabitEthernet0/0/3
description TEST
ip address <publiek IP + MASK>
no shutdown
!
ip route 0.0.0.0 0.0.0.0 <Provider GW>

What am i missing... Or not. Can someone help with this?

Hi @m.x 

 I dont see how it could be different. 

You mention VRRP, is this router the active?  This is the only default route on the router? Is there any dynamic routing protocol over there?

Thanks for your response. This one is passive, so traffic would be routed back to the Active on. I cannot bring that one down.. routing is doen by BGP and all ACL are on the uplink/NNI port. So If I connect to the ISP with above onfig I don't think I should have a problem. It just sounds to easy..
