methods for summarizing routes in FATKID ospf401
Hi, Just trying out ospf401 on fatkid, and was reading the hints about summarizing. Here's the hint "There are two built in OSPF methods to summarize OSPF routes. One way summaries between areas. The other summarizes between Autonomous Systems. Do you know a third way to summarize routes, which works for any router, running any routing protocol? How about a fourth?" http://www.fatkid.com/html/401_advanced_opsf_-_hints.html Does anyone know the 3rd or other ways and could kindly let me know?

Re: DLSW filtering
Hi Nigel,
Firstly, thanks for your help on this question. But I think if using
dmac-output-list, it should be done on R2 to control only the
specified mac on Ring 1 it talking to hosts on Ring 2.
Just curious (and been picky), it there any way of just configuring on
R1 to achieve this?

Hi all,
Got a question on DLSW filtering. Say all interfaces below are
configured for DLSW (ie e0 and tok 0 of R1, e0 and tok 0 of R2).
How to configure on R1 so that only hosts on Ring 1 with mac address
3000.3000. can talk to hosts on Ring 2?
Hosts on Ring 1 with other Mac address should still be able to talk to
hosts on e0 of R2.

Re: Multiple default gateways, same result?
Just on a Like Hubert was saying, the route for ethernet is redundant. But just on the side note, if you're pointing to another network of the e0 eg. ip route 123.0.0.0 255.0.0.0 e0, you want to make sure the next hop router on e0 will answer proxy arp. Because that's what the router arps for 123.0.0.0 what it wants to route to it. Clue.

Re: bridge vlan
I'm not much of a switching person, but here's my $0.02:
Adding a separate bridge device connecting the 2 vlan can do the job.
But why not just connect a cross over cable between the 2 vlan. Not
sure the pros and cons on this.
If you want 1 big broadcast domain (which is what you're doing), you
can just make it 1 vlan instead though.

EXTENDED ACL for distribute-list
Hi all, Could someone shed some light on how to use EXTENDED ACL for distribute-list? I'm trying to allow only 10.1.1.0/24 route to be distributed by eigrp 90. Below is config and debug ip eigrp output. I thought ACL 110 is a bit "relaxed" but should have allow the 10.1.1.0/24 route to be distribute out. But it got DENIED. ACL 10 worked. Initially, I had "access-list 110 permit ip 10.1.1.0 0.0.0.0 255.255.255.0 0.0.0.0" which I thought would be the most specific. But this didn't work also.

Those who are interested, contact me off line, and I will send you a text

Following is a routing table resulting from placing OSPF onto a router
already running EIGRP. Note that OSPF routes with a mask of /32 are being
placed into the routing table. I am not sure why this is happening. Several
tweaks have failed to eliminate these routes. Nor did changing the EIGRP
distance to 115 ( higher than OSPF's 110 ) eliminate EIGRP routes from the
routing table.
So now I have to wonder what is happening.
If no one has a quick and good explanation, I'll try to post configs and

Re: Up/up but no connection
Those 22 bytes would probably be the keepalive for HDLC if that's what
you're running. Interface would only go up/up if layer 1 2 is good,
in the case of HDLC it will need to see keepalive from the other end.
"debug serial interface" on both end would be a good one to check
this.
Personally, I haven't seen one end is up/up and the other is up/down.
I can only see this happen if the telco has misroute one end to
another site which happens to have the same setting. If anyone know
any other cases, please share with us.

Odd problem that has been solved to discuss.

was splitting off 5 channels for voice and sending the rest to the router
for data. Routers had no connection to the voice. Data was down but voice
was working fine.
This was a working setup, not a new install.
Router A had a Up/up on the interface, was getting 22 byte packets in. No
input errors. Not seeing any IGRP packets. I could not ping the serial
interface on router B.
Router B had up/down on the interface, sending (22 byte packets) and I didnt
check if it was recieving packets, but getting lots of CRC input errors. If
I did a local loopback on the Nx56/64 port on the Adtran, I would come up/up
and ping myself with no CRC errors. If I pulled the T1 outta the smartjack
and put in a hardloop, I'd be up/down and getting CRC. Replaced the Nx56/64
module and all was well.
The question is, what is the 22 byte packets coming in? What conditions need
to be met for the protocol to go up? I've never seen it up/up and not have a
connection.

suppose to be in the routing table. I'm assuming they're ip addresses
on loopback interfaces with /24 mask. You may want to try putting "ip
ospf network point-to-multipoint" (if the version of IOS support this)
and see if it makes a difference.
Clue.

Well, I couldn't resist. I had the router pod set up for a RIP to EIGRP

I would post configurations, but the file size exceeds what Paul allows.
Those who are interested, contact me off line, and I will send you a text
file with configurations and routing tables.
Following is a routing table resulting from placing OSPF onto a router
already running EIGRP. Note that OSPF routes with a mask of /32 are being
placed into the routing table. I am not sure why this is happening. Several
tweaks have failed to eliminate these routes. Nor did changing the EIGRP
distance to 115 ( higher than OSPF's 110 ) eliminate EIGRP routes from the
routing table.
So now I have to wonder what is happening.
If no one has a quick and good explanation, I'll try to post configs and
fool with this some more. Possibly I can place the routers on line and let
folks poke around
Look forward to some more discussion. Customer visits tomorrow, so I won't
be back on line until very late in the day.

Subject: Re: Migrating from EIGRP to OSPF
Hey, Brian,
Thanks for the info. I have some comments/clarification.
EIGRP carries a lower administrative distance vs. EIGRP.
CR: You mean EIGRP (90) has a lower AD than OSPF (110)?
So you can
basically turn up OSPF on your routers, and then when it all looks kosher,
what I would do is raise the administrative distance of EIGRP above
OSPF..this will cause the EIGRP routes to phase out and OSPF to
be used. If it all goes crazyyou can revert by simply moving
EIGRP back to the default administrative distance. If you were to have
cleared out your EIGRP
Re: I screwed up?
In case you're still working on it, you might want to firstly make
sure the IOS is indeed deleted. You can check this at rommon by
dir flash:
If the IOS is not there the URL below should help:

tftp is the faster way to go

Help!
I just passed the CCNA and got a job one week ago. Today I was given a 2600
router ( IOS 12.0 - BP 11.3) to do some basic configurations.
After the configurations I copy running-config to startup-config.
I noticed a message that said somthing like..You must delete Flash before
the configuration can be saved... I hit the return key and I think the flash
was deleted or somthing.
Now everytime I restart the router I get the following message:
UNABLE TO LOAD FLASH
How can I get the flash back?
THANKS FOR YOUR HELP

isdn backup
Greetings all, Got a question on routing with ISDN backup. Could someone shed some light on how to properly implement the backup command with routing? I'm using the backup command, and ip unnumber for both primary and backup interfaces. int loop 0 R3 int s0/0-primary--int s2 R5 int loop 0 (5.0.0.5) int di1---backup---int di1 Below is config. What static route can I use to complete the routing to the remote end? Because unnumbered addresses is use, I'm unsure what the static route should look like. The only thing I can think of is using floating static, but that sort of defeat the purpose of the backup command.

Re: isdn backup
Hi Erik,
I am just trying this out at this stage. For discussion sake, say I
want to get from r3 to network 2.0.0.0 which is on ethernet of R5:
r3-s0/0--primarys2 r5 ---e1 (2.0.0.0/8)
di1---backup---di1
till using unnumber loop 0 for both primary and backup int.
If static route is to be use, what should it look like?
Your first solution below is using floating static, which I know it
would work. But is there a way to do it without floating static?
Cause if floating static is use, the "backup" command seems
unneccessary.
Not exactly sure what you mean on the second solution, could you
provide sample config?
I got eigrp instead of static route to work earlier, was a bit
surprise to see r3, r5 form neighbor even though they're on different
subnet. r3 (3.0.0.3) r5 (5.0.0.5). does anyone know if this is
right?
ClueLess.

What are you trying to backup here? I don't see any routing. Start with a
working primary first and I can probably give you suggestions for a
solution.
Roughly, what you need are two static routes with different weights so the
primary is favored, and the backup is much more costlier, or, set the dialer
as the default route with a static 0.0.0.0 pointing to the primary, that
way, when the primary disappears, the static leaves the table and the dialer
goes up. remember to write an access list on the dialer to prevent dialing
for RIP updates, etc. depending on what type of traffic you have traversing
the router.
