Hi all The following are the configurations of the routers and the ping outputs. I have given 3 cases.
1) When ip unnumbered at one end and static routes are defined sdmheadend#sh run Building configuration... Current configuration : 1115 bytes ! version 12.2 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname sdmheadend ! ! ! ! ip subnet-zero ! ! ! ip audit notify log ip audit po max-events 100 ! ! ! voice call carrier capacity active ! ! ! ! ! ! ! ! ! mta receive maximum-recipients 0 ! ! ! ! interface FastEthernet0/0 ip address 172.20.110.10 255.255.255.192 duplex auto speed auto ! interface FastEthernet0/1 no ip address shutdown duplex auto speed auto ! interface ATM1/0 no ip address shutdown no atm ilmi-keepalive dsl operating-mode auto no fair-queue ! interface FastEthernet1/0 no ip address shutdown duplex auto speed auto ! interface Serial1/0 ip address 12.12.12.1 255.255.255.0 no fair-queue clockrate 2000000 ! interface FastEthernet1/1 no ip address shutdown duplex auto speed auto ! interface Serial1/1 no ip address shutdown clockrate 2000000 ! ip classless ip route 200.200.200.0 255.255.255.0 Serial1/0 ip http server ! ! ! ! call rsvp-sync ! ! mgcp profile default ! dial-peer cor custom ! ! ! ! ! line con 0 line aux 0 line vty 0 4 ! ! end sdmheadend# ping 200.200.200.11 Type escape sequence to abort.
