Using the Cloudstack definition of Network
Service<http://www.slideshare.net/kkitase/3-networking-cloudstack-developer-day>as
a foundation my question is: Should the VPC Virtual Redundant Router
be
considered a Network Service?

I'm conflicted. The user can turn on redundancy however the redundant
functionality is really a type of router, not a L2-L7 network function.

If not, should the implementation be implemented as an additional router
(virtual device, separate router vm template image, etc)  or additional
functionality (the ability to provide redundant services
without L2-L7 knowing about it) to the existing virtual router modifying
the existing router vm template?

A related question is should the vrr
protocol<http://en.wikipedia.org/wiki/Virtual_Router_Redundancy_Protocol>
used
by Keepalived <http://www.keepalived.org/> be passed on the Cloudstack
Management network or an isolated network between the master and
backup router?
