What is BGP and OSPF redistribution?

multilayer switch running following routing protocol: BGP and2 OSPF processes in area0 with following route redistribution

 

BGP routes are redistributed in OSPF process

OSPF routes are redistributed into OSPF, and vice versa ,,, routes are tagged to avoid looping

 

The problem is that BGP routes redistributed into OSPF are not redistributed into OSPF, and I think I need to redistribute BGP routes into OSPF as well

 

Is this normal that OSPF do not redistribute those BGP routes from one OSPF process to another ?

Yes it is normal for BGP not getting redistributed on OSPF process,

to redistribute you will need to add the command

# BGP redistribute-internal

in router BGP,

this will redistribute all BGP routes to OSPF process.

and also

#no auto summary

, since by default BGP will distribute routes after summary.

 

Thank you for asking the question. Please get back if your still not able to propagtes routes to OSPF process.
