problems with EIGRP config

Two routers DTN and MTN connected by ptp T1. Can ping all router s0 and e0 interfaces from each router back and forth. Cannot ping hosts on any e0 LAN from any remote router. Phone LAN is not in use or configured at this time. Internet access is via Firewall 192.168.1.6 at DTN. What am I missing? What should default gateway address be on hosts at MTN LAN

192.168.0.0 Thanks !!!

Default gateway for MTN hosts should be the directly connected ethernet interface of the router (192.168.0.2).

Jay,

On your DTN router your Ethernet0/0 interface does not parcicipate in the EIGRP. Notice, that you have IP address 192.168.1.2 for the interface, but in EIGRP you define 192.168.0.0 network. They do not match, so, the

192.168.1.0 network will not be advertised. You can use "show ip eigrp interface" command to see if your interfaces are included in EIGRP.

It works though in the MTN router. And by the way, your "router eigrp 2" section does nothing. You have no networks defined, and probably have no neighbors. So, you may delete it.

Should the default gateway on the DTN hosts (PCs attached to e0) be the e0 interface 192.168.1.2 or the internal ip address of the firewall

192.168.1.6 that goes out to the > Jay,

jayjay a écrit :

that depends. Do they need to access servers at the MTN location? Does your firewall support ip redirect?

It is safer to point your PCs' default gateway to the router and have it bounce the traffic to the firewall if required.

On DTN:

ip route 0.0.0.0 0.0.0.0 192.168.1.6 ! router eigrp 1 redistribute static

On MTN:

Nothing special, eigrp will take care of everything. In fact, you can even get rid of the static route you have there.

Jay,

On the DTN router you may put the static route:

ip route 0.0.0.0 0.0.0.0 192.168.1.6

Also, you should add following command into the EIGRP configuration:

router eigrp 1 redistribute static

This will redistribute default route to MTN router for 192.168.0.0 network.
