Explanation

When a router is configured as an EIGRP stub, it advertises only its directly connected and summary routes, and it does NOT advertise routes learned from other EIGRP neighbors (such as an external default route toward the Internet). If R1 (the distribution/hub router that has Internet reachability) is incorrectly configured as an EIGRP stub, it will not propagate the default or external routes down to R2 and the branch network. Issuing 'no eigrp stub' on R1 removes the stub restriction, allowing R1 to advertise all routes - including the Internet-bound default route - so that branch hosts on 2001:db8:0:4::/64 can reach the Internet.
