So, it keeps dialing over and over again.
I don't understand though.. I've marked eigrp as uninteresting, and yet it keeps dialing, when there's not supposed to be any traffic. ALl traffic should be routing through the serial link, and when it goes down, it should use the backup ISDN.
Any idea? It should just establish layer 2, but not try to establish layer 3 until a call is made.
Solved! Go to Solution.

If you do not wish to RX calls on this line , and if it is backup there is really no need to recerive calls , you can configure the command under the BRI
isdn reject data
isdn reject voice
10-02-2003 06:31 AM
Try adding passive-interface bri0 under the router eigrp process.
Also, I could be wrong but the output of your show isdn call shows the calls as "in". Could you the other router be calling up this router?
10-02-2003 06:41 AM
I tried making bri0 passive already.
the number showing up on the show isdn history is the number of spid 1, and the first part is the area code, preceeded by the number (1).
I find that strange too.
But, the router on the other side has an entirely different spid.
So in other words, it's as if the router is dialing it's own spid...
10-02-2003 06:31 AM
ok to fix the problem with the router keeps dialing
your acl 100 needs to be fine tuned
access-list 100 deny eigrp any any (this is good)good
access-list 100 permit ip any any
After your permit place the 'log' keyword
access-list 100 permit ip any any log
This will give you Source & dest ip addresses as well as port #'s , once you get this info you can determine what is placing calls.
You also have a problem with Spid 2 the switch is not recognizing the spids the router is advertising you can teel this by
TEI Not Assigned, ces = 2, state = 3(await establishment)
spid2 configured, no LDN, spid2 NOT sent, spid2 NOT valid
you are not getting TEI from the switch , Open a ticket with the provider .
the valid state for spids are init and established all other states are not valid you will not be able to place a call
10-02-2003 06:44 AM
The spids, prior, said state 5=(init), but the router still kept dialing... I interpret this as "initializing". ISDN calls were still successful, but I wanted to ensure that we weren't incuring any additional charges, as this was a problem in the past.
So, I removed the spids, re-inserted them and reloaded. Now it says SPID Not valid.. but I'm going to try and put the second one in again.
10-02-2003 06:47 AM
place the log statement at the end of the permit in acl 100 this will tell you who is dialing
10-02-2003 06:57 AM
I put the new ACL and Passive-interface on bri0/0,
access-list 100 deny eigrp any any
access-list 100 permit ip any any log
but all I'm seeing is this...

I think the box on the remote side is calling you can you do the same thing there and see what you see
10-02-2003 07:18 AM
SHow isdn history on the remote side reveals that no calls have been made...
in the show ISDN status, did you notice this??
Layer 3 Status:
1 Active Layer 3 Call(s)
CCB:callid=0, sapi=0, ces=2, B-chan=0, calltype=INTERNAL
CCB:callid=C, sapi=0, ces=1, B-chan=1, calltype=DATA
CALLtype=INTERNAL ???
that's odd, don't you think?
10-02-2003 07:21 AM
It only keeps the info for 15 minutes configure the log statment and wait for the next call

it's not configured to dial!
but, here's what the log says: (I did a clear log before I did a show log, what's up with the time/date stamp?)

Is there on openview box or some kind on network managements server 172.18.89.188 ?
10-02-2003 07:57 AM
No, I think that's actually a welchia-infected machine. I blocked ICMP.. same deal.

Your passive interface statement is pointing at the wrong interface:

add
service timestamps debug datetime msec
service timestamps log datetime msec
to your config to change the date/time stamps from router uptime to local date/time.
Also do a debug dialer events on both routers. This will tell dialing causes.
