Dear Michael,
I have found what the problem was. Before I explain what happen, please examine the
configuration of IP RIP and ip
configuration of serial 0 from the output bellow.
R3#sh ip int brief
Interface IP-Address OK? Method Status Protocol
Serial0 180.180.2.2 YES manual up up
Serial0.1 160.160.1.1 YES manual up up
Serial0.2 160.160.2.1 YES manual up up
Serial1 unassigned YES unset down down
TokenRing0 unassigned YES unset administratively down down
R3#sh running-config
router rip
network 180.180.0.0
network 160.160.0.0
!
no ip classless
!
I used the "no network 160.160.0.0" command to remove network 160.160.0.0 from rip
update. Although I did not
remove network 180.180.0.0, RIP suppressed update via serial 0 altogether, apparently
because network 160.160.0.0 is
configured for a subinterface of serial 0 !!!!
