The network administrator has configured router R2 to redistribute a newly installed EIGRP network into their core OSPF network. The redistributed networks and subnets are not properly appearing in the routing tables of the other routers. The following output displays partial configuration for router R2:router ospf 10
redistribute eigrp 50 metric 100 metric-type 1
network 126.96.36.199 0.0.0.255
What two modifications would correct the problem? (Choose two.)
- Change the EIGRP AS number from 50 to 10
- Change the AS number specified for OSPF to 50
- Add the command network 10.0.0.0 0.0.0.255
- Add the command network 10.0.0.0 255.255.255.0
- Add the level-1-2 keyword to the redistribute command
- Add the subnets keyword to the redistribute command
- Change the command network 188.8.131.52 0.0.0.255 to include the area keyword and value
The R2 router will not form adjacencies with neighboring routers in the area if the area IDs do not match. The area keyword in the network command is missing from the initial router R2 configuration. The correct command would be:
R2(config)# network 184.108.40.206 0.0.0.255 area 1
Secondly, the subnets keyword should be used in the redistribute command to ensure that all of the subnets in the 10.0.0.0/8 are redistributed into OSPF. For example, you would use the following commands to redistribute EIGRP autonomous system (AS) 50 networks and subnetworks into OSPF with a metric of 100 and advertise them as external Type 1 routes:
R2(config)# router ospf R2(config-router)# redistribute eigrp 50 metric 100 metric-type 1
The complete syntax for the redistribute command when used in OSPF is as follows:
redistribute protocol [process-id] [metric metric-value] [metric-type type-value] [subnets]
The command parameters are:
protocol – Identifies the source protocol, such as BGP, connected, EIGRP, IGRP, ISIS, OSPF, static, or rip.
process-id – Depending on the routing protocol, identifies the source autonomous system number or process ID.
metric – Identifies the seed metric for the redistributed route. The default is 0.
metric-type – For OSPF, it identifies the redistributed routes as either external Type 1 or Type 2 routes. The default is Type 2.
subnets – Optional keyword for use with OSPF to indicate that the scope of the networks to be redistributed also includes subnets.
