Is it possible to take tag values carried in OSPF external route advertisements and automatically map them into the community attribute of the respective BGP advertisement?
Consider a router running both OSPF and BGP. In the BGP config, there's a redistribute from OSPF into BGP. Assume that only OSPF external routes, and hence those with tag values, are being redistributed into BGP. Assume that these external routes have different tag values. Is there a way to automatically get each respective OSPF tag value into the community value of the respective BGP route advertisement? So, if an OSPF external route advertisment has a tag value of 42, when the route is redistributed into BGP, the respective BGP community value would be 0:42. If the OSPF tag value was 81, the BGP community value would be 0:81. It looks like it might be IOS possible to statically encode all the possible OSPF tag values, via a route-map, and then set the BGP community value. I've not actually done this yet, so not sure if its possible. However, I'd rather use an automated mechanism for this. That way, as new OSPF external tag types are used in the network, I don't need to update route-maps.
