Regarding "Blacklist of Routes" Feature of nTier Apps 2.0
Hello,
I referred to the Functional Specification present at https://cwiki.apache.org/confluence/display/CLOUDSTACK/nTier+Apps+2.0+Functional+Spec to understand what does blacklisting routes feature mean. Can anyone help me understand what does this feature do and how is it implemented on the Router?
Thank you,
Chandan.

Thanks Alena,
Added the mentioned test case to the test plan,
Thank you,

Although there is no harm in keeping this parameter for Basic zone as we don't do any verification against it, I might disable its update on the API level when the zone is Basic. You should add a test case for that.

Thanks Alena,
Do you prevent the execution of updateZoneLevelParameters API with "blacklistedRoutes" parameter on a Basic Zone? If No, then will an accidental execution of this API on a Basic Zone have any bad consequences on any functionality in the zone?
Thank you,
Chandan.

You have to specify the new list of the blacklisted routes excluding the one you want to drop. For example:
1)
updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24,10.1.2.0/2
4
2) if you want to drop the last route from the black list, execute:
updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24
Any zone configuration parameter will be stored as a String, and to update it with the new value, you will have to re-define the string anew.
Assuming your next question will be - how to re-set the parameter to Null/empty. For that, refer to Harikrishna Patnala - a developer for "Granular Global Config Parameters" feature. The feature's API should support resetting granular global configs.

You have to specify the new list of the blacklisted routes excluding the
one you want to drop. For example:
1)
updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24,10.1.2.0/2
4
2) if you want to drop the last route from the black list, execute:
updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24
Any zone configuration parameter will be stored as a String, and to update
it with the new value, you will have to re-define the string anew.
Assuming your next question will be - how to re-set the parameter to
Null/empty. For that, refer to Harikrishna Patnala - a developer for
"Granular Global Config Parameters" feature. The feature's API should
support resetting granular global configs.

Thanks Alena,
After I specify a list of black listed route CIDRs, how can I remove one of the CIDRs from the list without disturbing the rest of the CIDRs in the list,
Thank you,
Chandan.

The code won't allow to specify routes in "10.10,10.0/24,172.16.1.0/24"
format neither for blacklisted routes, nor for static routes. The format validation will be done for each cidr; and "," will be used as a delimiter.

Thanks for the Information Alena,
May I know the information for the following questions pertaining to the feature:
1. Format of Specified Black Listed Routes: In the FS, it is mentioned that we specify the routes as "10.10.10.0/24,172.16.1.0/24". Do you parse the network information using the "," as the delimiter for a value? If Yes, What happens if someone provides the input as "10.10,10.0/24,172.16.1.0/24"? Do you still successfully verify against the valid input "172.16.1.0/24" and ignore the "10.10,10.0/24" value?
2. Do you do a subnet check to prevent the blacklisted static route creation? I mean, if the blacklisted routes are "10.10.10.0/24,172.16.1.0/24", then do you prevent the static route creation for "10.10.10.20/26" network which is a sub-network for 10.10.10.0/24 network?
Kindly let me know,
Thank you,
Chandan.
