VASI NAT on an Multi-VRF Selection interface

[d.namza]

Hey there everyone,

I was wondering if anyone has ever implemented or tested VASI NAT with the 'ip nat inside' interface configured on a Multi-VRF Selection interface. Is it still possible?

Thanks!

Hello

Its IOS-XE version of vrf network translation, Basically its complied just like traditional nat but with the extra vasi interfaces required for communication between the  vrf's

These Vasi interfaces allow the translation between the vrf instances, As such any vrf static routes need to point to the opposite vrf physical subnet but with a next hop on the vasi logical interface 

The nat is performed from internal vrf inside local physical subnet to a external vrf inside global physical ip

Please review here:

Hi Paul,

Thanks for your reply. I've implemented it on a inside interface tagged as vrf and working as expected. 

Just wondering if it will work on a multi-vrf interface like below?

interface fastethernet0/0

ip vrf receive VRFA
ip vrf receive VRFB

ip policy route-map VRF-SELECT

ip nat inside

Thanks!
