It is interesting to see the route that disappears is seen over
fastethernet0/1.1. Is this a typo?

Subject: problem between ISL and RIP,IGRP with config
Hi all,
I have a problem on catalyst ISL Trunk problem.
my R5-router's loopback0 is 175.3.5.0/24.
R5 is connected to R6 via Fastethernet(175.3.56.5/24)
R6's interface is a Fastethernet 0/0.1(175.3.56.6/24)
between R5 and R6, if i run OSPF or EIGRP,
R6's routing table is good.
R6 has the 175.3.5.0 on its routing table.
but, if i run RIP or IGRP between R5 and R6,
R6 doesn't have the 175.3.5.0 on its routing table.
of course, R6 has the 175.3.5.0 in a short time.
but after a while, 175.3.5.0 is possibly down
and disappeared on R6 routing table.
so when i try to debug on R5 and R6,
R5 continue to send the 175.3.5.0 to R6,
but, on R6, the receiving debug message dose not show.
If i change the R6's ISL FastEthernet
to main FastEthernet
all routing protocol(including RIP,IGRP) is good.
is there any problem between ISL and RIP,IGRP?
Any suggestions on what I am doing wrong?

1~2 minute later R6's table
R6#sh ip route

I 175.3.5.0/24 is possibly down,
routing via 175.3.56.5, FastEthernet0/1.1
======================================================
if i change the R6's ISL interface to main interface,
this problem is disappeared at once.
