Subject RE: Regarding "Blacklist of Routes" Feature of nTier Apps 2.0
Date Mon, 08 Apr 2013 21:18:09 GMT
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.

The check will be done only on createStaticRoute command execution.
