BGP - bgp redistribute-internal command

When redistributing BGP routes into an Interior Gateway Protocol (IGP) such as OSPF or EIGRP, by default iBGP learned routes are not redistributed into the IGP.

However, if you choose to force such redistribution, you can do so with the bgp redistribute-internal command under the BGP router configuration mode.

The clear ip bgp command must be entered to reset BGP connections after this command is configured.
