EIGRP - how to use "ip default-network" command?
Hi Everyone,
I'm studying for my BSCI exam - EIGRP and trying to get the "ip default-network" command to work correctly.
I have three routers in a rectangle, and have added an int l666 interface with an IP of 6.6.6.6/32. I've included network 6.0.0.0/8 in my EIGRP networks and the other routers are seeing it from EIGRP.
When I go to add the "ip default-netwok 6.0.0.0" command, to make it the default route and advertise that through eigrp it's not working. I have tried it several ways, but it just won't work.
Could anyone tell me what I'm doing wrong?
Thanks,
PC

Hi ksims,
Congrats on passing - I failed a month ago ... :(
Ok - here's me doing what you say and it not working.
I created a loopback, L666
I added an IP to it 6.6.6.6/32
I added network 6.0.0.0/8 to eigrp 100
I verified on router 2, that it got the route for 6.0.0.0 through eigrp
On Router 1, I issued "ip default-network 6.0.0.0" and saw it in the route table, on router1
On Router2 - still no candidate default.
I'm pasting all of this below - first router 1, and then below that router2 with the show ip route at different stages.
Thanks for your help,
PC

Router2#
Congrats on passing - I failed a month ago ... :(
Ok - here's me doing what you say and it not working.
I created a loopback, L666
I added an IP to it 6.6.6.6/32
I added network 6.0.0.0/8 to eigrp 100
I verified on router 2, that it got the route for 6.0.0.0 through eigrp
On Router 1, I issued "ip default-network 6.0.0.0" and saw it in the route table, on router1
On Router2 - still no candidate default.
I'm pasting all of this below - first router 1, and then below that router2 with the show ip route at different stages.
Thanks for your help,
PC

Router2#
thats not what i said.
Router11(config)#ip default-network 6.0.0.0
Router13(config)#ip default-network 6.0.0.0
you have to issue the command on every router that you want to use 6.0.0.0 network as the default network.
Router11(config)#ip default-network 6.0.0.0
Router13(config)#ip default-network 6.0.0.0
you have to issue the command on every router that you want to use 6.0.0.0 network as the default network.
ASKER
You do!?!?
I thought it's supposed to propagate through the EIRGP domain.
"A router configured with this command considers the network-number the last-resort gateway that it will announce to other routers. The network must be reachable by the router that uses this command before it announces it as a candidate default route to other EIGRP routers. The network number in this command must also be passed to other EIGRP routers so that those routers can use this network as their default network and set their gateway of last resort to this default network."
If I have to go issue this command on every single router - why wouldn't I just manually set the default gateway while I'm there?
Plus, ..."Multiple default networks can be configured: downstream routers then use the EIGRP metric to determine the best default route".
It sounds to me like this command is used near the Internet edge of the network - then the rest of the EIGRP domain learns of it.

Yes you do. It does not propagate the route in EIGRP. the only way to redistribute it is to use the command Router(Config-router)#redi
this will inject any static routes you have configured. you can use route maps to make sure the right static routes get redistributed.I dont know of any other way. If someone does please chime in.

Well, while we're waiting on others to chime in ... ;)
You can configure a default route at your edge - like 0.0.0.0 0.0.0.0 next hop x. Then, if you go into EIGRP and advertise network 0.0.0.0 - all your other EIGRP routers will learn about the default route that way - but that's not using the command - it's "cheating". :)
Still - it really looks to me like this command is supposed to propogate.

Ok, I found this:
"Gateways of last resort selected using the ip default-network command are propagated differently depending on which routing protocol is propagating the default route. For IGRP and EIGRP to propagate the route, the network specified by the ip default-network command must be known to IGRP or EIGRP. This means the network must be an IGRP- or EIGRP-derived network in the routing table, or the static route used to generate the route to the network must be redistributed into IGRP or EIGRP, or advertised into these protocols using the network command"

ok. that sounds how i learned it. So, The best way to do it is redistribute the static route

So... you think I'm making a moutain out of a mole hill? The way I'm doing the command is correct - and should work - and to move on? ;)

Addendum - turns out my Sr. Engineer found the answer. The network wasn't being summarized going out the interfaces. So, the other routers had a more specific route and were choosing it. Once summarization was put on the interfaces, it worked like a charm.
Gateway of last resort is 192.168.2.1 network 6.0.0.0
If you have any questions let me know.i will also see if i can find somethind on the cisco site to send you.
