Advertising loopback interfaces via IGRP. [7:32498]
Hi all, The scenario is this : R2R3---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?

Rajesh, As far as r4 is concerned, you should see the network as being directly connected via loopback0 in the routing table and not learned from IGRP. Also, I'm wondering why you have IGRP turned on for the 200.0.0.0 network and are resdistributing connected. With just the 200 defined in IGRP, R2 should learned about that network. I think you may be having issues with the have that you have both the network statement for that network and also the redistribution of connected. Try removing the redistribution command. Or maybe i'm completely off, in either case, hopefully others will respond.

Re: Advertising loopback interfaces via IGRP. [7:32498]
you have a classful issue here. IGRP will not advertise the host route 200.0.0.0/32 if you do a show ip protocol you will also see that the IGRP network installed is 200.0.0./24 IGRP is confused. BTW do you have ip subnet-zero configured? Rajesh Kumar wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
