After the configurations, execute the display ip routing-table command on each device. The output
shows that each device has learned the route to the LSR ID of the other device in the same AS. Take
Router A as an example:
[RouterA] display ip routing-table
Routing Tables: Public
Destinations : 6 Routes : 6

3. Configure BGP on Router B and Router C and redistribute routes, ensuring that the ASs can
communicate with each other.
