------------------------------------------------------------------

My colleagues and I have been tasked by our company, Sungard, to implement and 
test the functionality of this JIRA.

We have done some preliminary work and I will outline what we've found and 
several questions we have.

We will certainly have more questions/comments, but this is a good start.

Please comment, correct or add to the statements and questions below:


We have referenced:
# About RvR

http://blogs.clogeny.com/understanding-the-redundant-virtual-router-in-citrix-cloudplatform/
 .
# Cloudstack function spec for RvR 
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Redundant+Virtual+Router+Functional+Spec
 .
# Cloudstack function spec for new VPC features

https://cwiki.apache.org/confluence/display/CLOUDSTACK/nTier+Apps+2.0+Functional+Spec
# Implemented codes for RvR
Mostly it's in VirtualNetworkApplianceManagerImpl, 
as well as redundant_router directory of systemvm and in cloud-early-setup.



What we  know:

# Redundant Virtual Routers (RvR's) are used in CloudStack public clouds per 
item 4 above.
# The public RvRs are provisioned with the templates contained in 
redundant_router directory of systemvm.
# Keepalived and Conntrackd do most of the "heavy lifting" monitoring and 
transitioning the current RvR's in public clouds.
# Keepalived and Contrackd are setup with templates by systemvm.
# The setup_router script calls the setup_redundant_router to provision a 
redundant router pair for a vm.
# We will need to confirm each router of a redundant pair is provisioned under 
a separate Hypervisor to allow for no single point of failure.

Questions:

# Are there any other references which might be helpful?
# It seems the VirtualNetworkApplianceManagerImpl and associated classes should 
be useable for vpcRvR's are there  any gotcha's we should know about when using 
this class hierarchy ?
# Are there any other single points of failure other than the unique Hypervisor 
mentioned above?
# Can setting up a redundant router pair for a vpc be done by simply adding a 
call to setup_redundant_router script in the setup_vpcrouter routine for each 
vpcRouter marked as redundant?
