recently Ive been thinking about migrating from our current ospf (for v4) and ospfv3 (for v6) to only ospf3 (for v4 and v6) using realms. I labbed this and have 2 questions:
1- we use mpls/ldp/rsvp over ospf at this time which means we are using traffic-engineering options under protocol ospf. when I tried this with ospf3, the config required "shortcuts" option to be added in there. when adding that option, rsvp still remains down with all labels down. I see my routes and everything however labels remain down. is there a particular command to add for this situation?
2- since this migration needs to be done in stages, what is the best or recommended way to migrate from ospf to ospfv3? in my lab I see that routes are not distributed between ospf and ospf3. Im pretty sure this is by design but would like to have someone confirm that. also if thats the case, is route redistribution between ospf and ospf3 recommended? why yes, why not?
