Hi all, The scenario is this :
R2------------------------R3-------------------R4 R3 is a FR switch between 2 DTE devices R2 and R4. R4 is having a loopback interface, ethernet interface and a serial interface. I am running IGRP 2 on R4 on loopback and serial interfaces. I have not included the ethernet interface in the config. Assume, I have assigned the IP for the loopback as 200.0.0.4/32 The config is this : router igrp 2 net 150.50.0.0 net 200.0.0.0 redis connected default-metric 64 1000 255 1 1500 When I issued "sh ip route" in R4 : sometimes the loopback interface is advertised as IGRP route properly and sometimes it shows "possibly down" network. I couldn't seem to get the timings of when it was up and when it is going down. Any insights in this please?
