Which two statements about redistribution are true? (Choose two)

By default, when BGP routes are redistributed into OSPF, only eBGP routes are advertised; iBGP routes are typically not redistributed into an IGP to prevent routing loops and maintain BGP's path attributes.

When EIGRP routes on a Customer Edge (CE) router are redistributed through a Provider Edge (PE) router into BGP in an MPLS VPN, the Cost Community Extended Attribute (POI) is often used to carry EIGRP metric information, allowing proper path selection within the BGP cloud and back to other EIGRP domains.

When EIGRP routes are redistributed into BGP, a default metric is not strictly required because BGP uses a different set of path attributes (like AS Path, Local Preference, MED) for path selection, not a simple metric.

When BGP routes are redistributed into an OSPF routing domain, OSPF requires a metric for path calculation. If no metric is explicitly configured during the redistribution, OSPF assigns a default metric of 1 to these external routes.

iBGP routes are not automatically redistributed into IGPs (such as OSPF or EIGRP) even if they are in the routing table, primarily to avoid routing loops and respect BGP split-horizon rules; explicit and careful redistribution is needed.

When OSPF routes are redistributed into BGP, both internal (intra-area, inter-area) and external (Type 1, Type 2) OSPF routes can be redistributed, depending on the configuration and whether they are present in the routing table, making the statement generally true but less specific than B and D.
