Hi,
Reference to the attached diagram, have redistributed EIGRP and OSPF on R5,
when I traceroute from R1 to 150.1.10.10, It prefer via eigrp, but when I
apply 150.1.10.10 255.255.255.255 150.1.0.5, it still prefer eigrp to reach
150.1.10.10, but when I apply 150.1.10.10 255.255.255.255 s1/0, it is
unreachable, unable to unserstand the reason, please find the attached
config of R1, R5, SW4.
Regards,
Masroor Ali
