------------------------------------------------------------------
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:
1. About RvR
http://blogs.clogeny.com/understanding-the-redundant-virtual-router-in-citrix-cloudplatform/
2. Cloudstack function spec for RvR
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Redundant+Virtual+Router+Functional+Spec
3. Cloudstack function spec for new VPC features
https://cwiki.apache.org/confluence/display/CLOUDSTACK/nTier+Apps+2.0+Functional+Spec
4. 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 any gotcha's we should know about?
# 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?
