Hi, Does anyone have any pointers to some real-world use cases for VASI interfaces on an ASR1k? I have a corner case where I can't use MP-BGP to import a route from one VRF into another, when the next-hop of the route is in a separate VRF (the case is VRF-aware IPsec with FVRF/iVRF configuration). It looks like the issue can be worked around using VASI interfaces (i.e. a vasileft/vasiright pair). I have used a /30 to address the VASI interfaces and this appears to work, but is this best practice? NAT may be another useful requirement in this scenario, but I have seen other cisco-nsp postings which suggests 'ip nat outside' shouldn't be configured on an interface which isn't in the global table. A suggestions is that "ip nat enable" and hence NVI be used in preference to classic NAT for VASI interfaces? VASI does appear to be a rather poorly documented feature in IOS-XE :)
