[OpenAFS] Questions about multihoming servers

I have two general questions about multihomed AFS servers to pose to list.


- Is there any obvious reason to choose multihoming of a fileserver rather 
than link aggregation, assuming both are supported in a given environment?


- The Admin Guide on docs.openafs.org indicates that multihomed DB servers 
work.[1]

Is this true in an environment where both IPs are on the same (campus) 
network and they may share the same default route?

Specifically, I'm curious about linux dbservers; clients may contact the 
server via IP A but get an answer from IP B, if it is the default 
interface. Will the clients care? What if the IP replying isn't in the 
client's CellServDB (or DNS) at all? Does the answer change depending on 
client version?
