If a metric is not specified for routes that are redistributed into OSPF， the default metric that is assigned to the routes is 20， except for redistributed BGP routes. What is the metric that is assigned to redistributed BGP routes？（）

A.0
B.1
C.10
D.20

A.If another path advertises the 6.6.6.0/24 path and has the default local preference， that path is more preferred
B.The command neighbor send-community is configured on BGP neighbor 10.10.23.3
C.The route 10.10.23.3 is not being advertised to other BGP neighbors
D.Route 6.6.6.0/24 is learned by an IBGP peer
