Refer to the exhibit.
This network is running OSPF and EIGRP as the routing protocols. Mutual redistribution of the routing protocols has been configured on the appropriate ASBRs. The OSPF network must be designed so that flapping routes in EIGRP domains do not affect the SPF runs within OSPF. The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains. Which technique accomplishes the requirement?

Refer to the exhibit: A customer is migrating from a TDM-based Layer 2 VPN (L2VPN) to an MPLS Layer 3 VPN (L3VPN) in phases. The backbone OSPF connection between HUB A and HUB B will be replaced by eBGP. During the migration, some spokes (A2 and B1) are already moved to the L3VPN. The goal is to avoid routing loops during this hybrid transition.
Which design choice helps prevent routing loops during the backbone link migration?
