Hi,
I'm trying to distribute application specific data amongs nodes. To do that
I'm trying to run ospfd on each node and set up a full gre tunnel mesh among
them. This application specific data contains amongst others:
- a network prefix
- an IP address owning that network prefix
- ...
An example of this could be:
[ 10.0/16, 1.1.1.1, ... ]
[ 10.0/16, 1.1.1.2, ... ]
[ 10.0.0/24, 1.1.1.3, ... ]
[ 20.0/17, 2.2.2.1, ... ]
[ 20.0/17, 2.2.2.2, ... ]
So, let us say one node will inject this info into the mesh. The assumption
here is that the other nodes will receive this information (am I correct)?
Now, let us say one of the other nodes needs to do a look up on 10.0.0.1 and
the answer must be
[ 10.0/16, 1.1.1.1, ... ]
[ 10.0/16, 1.1.1.2, ... ]
[ 10.0.0/24, 1.1.1.3, ... ]
Basically "get me all the entries where 10.0.0.1 matches the prefix".
Questions I have:
1- Can the data distribution be done with opaque LSA injection? If so, any
pointers or documentations that can get me going?
2- Can the key lookup be done somehow through the ospfd's opaque table or
should i keep track of the distributed table in my application and do a
lookup myself?
3- If the answer to #2 is that the application must maintain teh data set
and perform the lookup, what is the best solution for the radix lookup? Is
there a library i can use to build the radix tree?
Many thanks in advance.
