Hi, All
I am configuring EIGRP in Packet tracer, after configuring
all the things it is not working but in one condition it is
working fine if i am putting all my router and network
withing one network subnets e.g. 172.16.0.0 or 10.0.0.0 but
whenever i am puting different network subnets e.g. in one
network it is RA(config-if)#=ip address 10.0.0.1, and in
fa0/0= 192.168.1.10 and in RB(config-if)#10.0.0.2 (s1/0) and
in S1/1 11.0.0.1 and in fa 0/0 192.168.100.1 ,where as in
third router RC(config-if)#=ip address 11.0.0.2 and in fa
0/0 172.16.1.10 and after configuring all this serial is
showing up and protocol showing up but eigrp process not
taking place after adding eigrp configuration, i tried with
"no auto-summary" command but not working.. Suggest me where
i missing something? can mail me at : gtech.innovator@gmail.com

interface Ethernet0
ip address 3.3.3.1 255.255.255.252

interface Serial0
ip address 23.23.23.3 255.255.255.0

router eigrp 100
network 3.0.0.0
network 23.0.0.0
no auto-summary

trouleshoot it with that comand


show ip route—This shows all IP routes available on the
router. Note that routes with a code of D indicate an EIGRP
route.
show ip eigrp neighbors—This shows all EIGRP remote routers
we are communicating with (better known as neighbors).
show ip eigrp interfaces—This shows all interfaces on the
router that are being advertised by EIGRP and that are
broadcasting EIGRP Hello packets.
show ip eigrp topology—This shows the EIGRP topology table.
show ip eigrp traffic—This shows EIGRP packets sent and
received.

debug eigrp neighbors and debug eigrp packets. Both of these
commands will provide tremendous insight into how EIGRP
works, what it does, and when it does it.
