So I'm having alittle bit of a senior moment and my google-fu has also let me down. In short I am looking to stand up some additional hoot and holler instances on some 4K series routers we have. We don't use it often or in a large scale so anything I remembered about it was quickly forgotten. My specific question has to do with the VIF interface. I recall the purpose of the VIF interface is to act as the source IP for said Voice port/Dial peer when transmitting. With that said lets say I have 8 Voice ports and setup 8 dial peers with unique multicast addresses. Can I configure the VIF1 interface with say a 192.168.1.1/30 IP or would it have to be a 192.168.1.1 /28? It's been awhile and the deployments I've done in the past were smallish (1-2 devices). I'd like to keep it to the smallest subnet I can due to some discontiguous subnetting that was done long ago that can't really be easily cleaned up. IE I'd love to use these little scrap areas if I can. Thanks.
