Redistributing iBGP Routes into IGP

Perform this task to redistribute iBGP routes into an Interior Gateway Protocol (IGP), such as Intermediate
System-to-Intermediate System (IS-IS) or Open Shortest Path First (OSPF).
Note Use of the bgp redistribute-internal command requires the clear route * command to be issued to
reinstall all BGP routes into the IP routing table.
Redistributing iBGP routes into IGPs may cause routing loops to form within an autonomous system. Use
Caution
this command with caution.

Purpose
• The as-set keyword generates autonomous system set path
information and community information from contributing paths.
• The as-confed-set keyword generates autonomous system
confederation set path information from contributing paths.
• The summary-only keyword filters all more specific routes from
updates.
• The route-policy route-policy-name keyword and argument
specify the route policy used to set the attributes of the aggregate
route.
