Redistribute between OSPF EIGRP issue

shush

Hi,
I'v got an exercise that including ospf with multi area (using virtual-link, because area 2 isn't directly connected to area 0 ) and redistribute between eigrp and ospf.
i have problem with the redistribution. The ASBR is R6. I don't have ping between R7(that is running only eigrp) between all the routers (R1-R5) that are running only ospf- R7 not get the routing of the ospf from R6.
I am new with all the redistribute subject, so i hope someone here can help me with it. I'm adding here picture of the topology and my configuration of all the routers:

Could you provide more information.

1. Please post the routing table of at least R6 and R7
2. Please run a traceroute from R7 to one of the OSPF routers and post the results.
3. Please test to make sure that routing between all OSPF routers is working correctly. So ping and or trace route between R6 and R1

I glanced at your config and R6 is not complete R1 has a network statement for a network that is not attached to a interface. And I think I saw a couple of network without network statements. I would double check each router config again.

Simrid

When you are configuring redistribtion, devices need to learn how to reply to the ping (icmp-echo). I would suggest trying either a stactic route on your EIGRP node or redistributing from OSPF into EIGRP. Remember, when you are redistributing into EIGRP you will need to define the metrics.

You have a few problems here.

1) You're not putting your loopbacks into OSPF or EIGRP.

2) From Redistributing Routing Protocols - Cisco

"IGRP and EIGRP need five metrics when redistributing other protocols: bandwidth, delay, reliability, load, and MTU, respectively. An example of IGRP metrics follows:"

There are 2 ways to do this

For all protocols being distributed into EIGRP:
default-metric <bandwidth> <Delay> <reliability> <load> <MTU>

eg
default-metric 10000 100 255 1 1500

Or just for OSPF
redistribute ospf 1 [FONT=arial, helvetica, Helvetica Neue, HelveticaNeue, Lucida Grande, sans-serif]<bandwidth> <Delay> <reliability> <load> <MTU>


[/FONT]Once these two issues are corrected you should have full reachability.

Some great catches here. I'm interested to see what the OP has for us after looking into this.
