John, Thanks for wrecking my weekend too...... I tried to get this to work using the tunnel method and the secondary addressing method but with no success.
My lab looks look like this r4--(igrp/27)--r2--(igrp/27)--r1--(igrp /27)--r8--(ospf /28) interfaces r4/r2 network 172.168.10.80/27 r2/r1 network 172.168.10.64/27 r1/r8 network 172.168.10.16/27 r1/r8 tunnel 172.168.11.0/27 r8 network 172.168.10.32/28 I tried all combinations of /27 & /28 masks on the tunnel to try and get the /27 routes into the table on r1 but with no joy. Look at this form debug ip igrp trans 04:49:59: IGRP: sending update to 255.255.255.255 via Tunnel0 (172.168.11.1) 04:49:59: subnet 172.168.10.32, metric=6882 So the route appears to be advertised out of tunnel0 towards r1 as you would expect , because the mask is the same. However the route never appears in the routing table on r1 although it has an interface using a /27 ( tunnel ) You do not see r1 receiving the /27 route I would like to hear your thoughts as I cannot think of another way to get around this one.
