BGP MED value redistribute to OSPF,How can do ？

[Ru Song Fu]

HI Guys:

This topo,RA and RD each have routing 192.1.1.1. have different MED properties. Will be redistribute to OSPFIn RTB&RTC. I want to see their METRIC on RTF. According to the metric to select the optimal route（BGP MED）, If you do not use the route-map, How to achieve? I don't to use route-map when redistribute at RTB and RTC.B

But BGP direct redistribution to OSPF is lost Med attribute.

Ask other method?

hi...

i am not sure if this is a valid option, but I seem to remember that you can use the "default-metric" values on RTB & RTC when redistributing routes in to OSPF... just simply make sure that the default metrics on RTC is more preferred than RTB (or vice versa).

You cannot parse BGP MED in to OSPF...

What you can also do is create an IBGP relationship between RTB & RTC and then use Local preference so that BGP chooses the correct path out of the AS domain

Mario Thank you answer.

RTA&RTD Each side has many of the same subnet, not only 192.1.1.0.They have different destination,So "default-metric" can't use.

I also cannot create a ibgp between RTB & RTC.
