多项选择题Process OSPF 1 is redistributing routes from process OSPF 2. Which of the following methods may be used to set the metrics of the redistributed routes?（）

A. Let the metrics default.

D. Redistribution is not allowed between two OSPF p rocesses.

单项选择题Router R1 has a connected route for 10.1.1.0 24 off interface Fa0 0. Interface Fa0 0 has been enabled for OSPF due to a router ospf 1 and network 10.0.0.0 0.0.0.255 area 0 command. R1 also has EIGRP configured, with the redistribute ospf 1 metric 1000 100 10 1 1500 command configured under EIGRP. Which one of the following is true?（）

A. R1 will not redistribute 10.1.1.0/24 into EIGRP, because R1 knows it as a connected route and not as an OSPF route.
B. For any OS PF routes redistributed into EIGRP, the metric components includea value equivalent to 1 Mbps of bandwidth.
C. For any OSPF routes redistributed into EIGRP, the metric components include a value equivalent to 100 microseconds of delay.
D. No subnets of network 10.0.0.0 will be redistributed due to the omission of the subnets parameter.

C. Set the metric components using the default - metric router subcommand.
D. Set the integer (composite) metric using the redistribute command's metric keyword.
