Right the default route would work nicely with bgp free core and no IGP on the Intra-AS-RRs But it won't work for Inter-AS-RRs Because you don't wan the local AS IGP to be "polluted" with the remote ASNs PEs and Inter-AS-RRs loopbacks so you rather want to carry those in bgp-afi-ipv4 + labels In this case you need the bgp-ipv4-afi to feed the FIB and LFIB on the Inter-AS-RRs As you need the end to end LSPs in order to setup sessions between Inter-AS-RRs in different ASNs

Not necessary - the majority of troubleshooting cases will be for customers in the network. We run a BGP-free core, but the route reflectors have direct access to the edge, so IP forwarding would suffice.
