Cisco “bgp redistribute-internal” command.

Quick note for myself regarding “bgp redistribute-internal” command that I ALWAYS forget to put in that costs me some time to troubleshoot the issue.

As you might know, by default, iBGP learned routes are not forwarded to an IGP routing protocol through the redistribute command. To change that behavior, we have to use “bgp redistribute-internal” command under the BGP process on the redistributing router:

router bgp X
 bgp redistribute-internal

Additional info:
Redistributing Internal BGP Routes Into OSPF
Configure Redistributing Internal BGP Routes into IGP

Good luck!
