5.8.1 Establishing the Configuration Task
Before controlling OSPFv3 routing information, familiarize yourself with the applicable
environment, complete pre-configuration tasks, and obtain the required data. This can help you
complete the configuration task quickly and accurately.
Applicable Environment
Through the configuration in this section, you can control the advertising and receiving of
OSPFv3 routing information and configure OSPFv3 to import external routes.
Pre-configuration Tasks
Before controlling OSPFv3 routing information, complete the following tasks:
l Enabling IPv6 capability
l Configuring Basic OSPFv3 Functions
Data Preparation
To control OSPFv3 routing information, you need the following data.
No. Data
1 Prefix of IPv6 routes after aggregation
2 Filtering list or name used to filter routing information
3 Link cost on an OSPFv3 interface
4 Maximum number of equal-cost routes
5 Name, process ID, and metric of external routes to be imported
5.8.2 Configuring OSPFv3 Route Aggregation
An ABR can summarize routes with the same prefix into one LSA and advertise the summarized
route in other areas. This can reduce the size of the LSDB in other areas.
Context
If multiple continuous network segments exist in this area, use the abr-summary command to
summarize them into one network segment. In this way, the ABR only sends an LSA after
summarization. No LSA that belongs to the summarization network segment is separately
transmitted, thus reducing the LSDB size of other areas.
Procedure
l Configure route summarization on an ABR.
Do as follows on the ABR that runs OSPFv3:
