Configuring RIPng route summarization
Configure route summarization on an interface, so RIPng advertises a summary route based on the longest match.
RIPng route summarization improves network scalability, reduces routing table size, and increases routing table lookup efficiency.
RIPng advertises a summary route with the smallest metric of all the specific routes.
For example, RIPng has two specific routes to be advertised through an interface: 1:11:11::24 with a metric of a 2 and 1:11:12::34 with a metric of 3. Configure route summarization on the interface, so RIPng advertises a single route 11::0/16 with a metric of 2.
To configure RIPng route summarization:
Step | Command | Remarks |
