Step-by-Step Process of Route Aggregation
1. Identify the Routes to Aggregate
The various routes through which B2B‘s online aggregators are available are as follows.
2. Calculate the Summary Route
However, following the usual route summarization method, where the ‘1s’ are aligning, the summary of the given IP prefixes are as follows:For example, the prefixes 192.168.1.0/24 and 192.168.2.0/24 can be summarized to 192.168.0.0/22.
3. Advertise the Summary Route
It also means it is more efficient to tell other routers about an area where the summarized route can be found rather than telling them about the specific routes to another router destination.
4. Update the Routing Table
In this case there should be an entry of the summarized route within every router for the purpose of reducing total routing table entries so that the routings can be eased.
BGP Route Aggregation and Route Summarization
BGP route aggregation and route summarization are key techniques used to optimize the routing process in large networks. Route aggregation involves combining multiple specific IP routes into a single, broader route, reducing the number of routes that need to be advertised and maintained.
In this article, we are going to discuss BGP in detail along with proper diagrams and explanations.
