Hi, actually it is Eigrp that has a better AD than Igrp, 90 and 100, respectively, the route u see in ur table has 170 as the AD, therefore External EIGRP,caused by the implicit redistribution, imposed when using these routing protocols with the same AS. so u are having normal behavior of the protocols. but i can't figure out why u r using IGRP in R3, since obviously he would know about the routes. Regards, Amar.
