I have applied a crypto map (fo ipsec vpn) on the dialer interface (for PPoE connection) in Cisco 2800; every time when the router restarts the crypto map is removed from the dialer interface even though i save the configuration every tim when i apply the map on the interface. Is there any way that the crypto map remains there on the dialer interface after the restart of router.

We have recently deployed several Ciso 887VAW (IOS 15.1(4)M4) to customer premises and I have come to realise counters show extremely high (not at all accurate) output rate and packets on all of them. [code]
View 2 Replies View RelatedI have an 837 ADSL router that the customer is upgrading from a 3 meg circuit to a 10 meg circuit.
The previous vendor used PPOE for connection and we used a dialer 1 interface to make the connection with a user name and password.
The new connection is a straight WAN DHCP no username or password needed.
I realize I can change the dialer interface from negotiate to DHCP but do I still need it ?
Can I replace the dialer 1 interface with IRB ? Should i just keep the Dialer 1 interface since the device is currently set that way and just remove the PPP negotiation from dialer 1 ?

As much as I understand, the VPN tunnel is active.I can access the Internet, but I cannot access anything through the VPN tunnel.
having some issues with a configuration using a Dialer interface. The interface comes up and the VPN tunnel comes up, but cannot access any network resources or the Internet.
The things that concern me most are my access lists as I have the static IP address that we are assigned via PPPOE - the IP never changes, but not sure if I can define it in the ACL or if I should be using an ANY tag.
Note: I've changed some IPs and username for security reasons.

I have two 3825's. Each has it's own ISP connection. Nat is configued for both. They have an ethernet connection between them and I'm running OSPF between the two so the routes propogate. I have qty 11 Dialer interfaces configured on each router (each router has an exact copy of the other routers dialer interface). However, I only want the Dialers up if the ISP connection on the mated router goes down. Much like HSRP I need one to preempt and be active if both ISP connections are up. When one goes down the other Dialers must come up. Each dialer sends a Dynamic DNS host name and IP address pair to DynDNS.org. So I cannot have both up otherwise the DNS names will bounce between ISP#1's IP address and ISP#2's IP address (back and forth). Let me know if any option exists to make this happen. As an aside the ISP's are providing me DHCP addresses so I cannot work off of an IP, it has to be the physical interface (i.e. Gi0/0).

I'm trying to find out what is the minimum downtime for a Cisco 2800 series LAN interface configured as DHCP client, in order to initiate a new DHCP discover. How much time does it need to take for the Cisco to "sense" the phy disconnection ?
View 4 Replies View RelatedI'm trying to add some 2800 series routers to our monitoring environment, but I can't get them discovered.
On the Mgmt Server I need to go through a "discovery" process to add the 2800 to the system. For this I target the internal interface ( i) but the discovery fails. I'm assuming the packets are getting dropped on the outside interface (e). I know SNMP is set up correctly and works as I had PRTG installed on a local box (p) for testing purposes.
The intention is to do the data gathering via a proxy agent (p), so enableing SNMP on the outside interface is not going to do me any good.What do I need to do to let those discovery packets pass through? At least temporarily?
It is a single router with dual ISPs. It is a 2800 and there is failover configured. I have implemented object tracking and the feature works great except that lately, whenever there is a lot of traffic coming perhaps from the internal users, we start getting intermittent outages.
I have gone deep into looking into this problem and have determined that our ISP#1 does not have any problems. What I think is happening is that whenever the router receives a lot of packets (30-40 users on the internal network) destined to the outside, the router CPU maybe gets too busy and the router then believes that the objects are no longer reachable and it triggers a failover which causes the router to re-direct traffic to the ISP#2. Then, because these are just quick burst of traffic, in the next 30 to 45 seconds after the router re-directed the traffic to ISP#2, the router object tracking engine detects that the objects are now again reachable and this then causes the router to re-direct all traffic back to ISP#1.
This cycle then continues all day on how to prevent this.
Is there a way to perhaps tell the router to completely shut down the interface facing ISP#1 whenever there is a hicup and to keep it shutdown for at least 8 hours? This way I can prevent the router from going crazy.
Or is there a way to perhaps prevent this at the internal (LAN) interface? Are there some metrics like QoS that I can implement on the internal Fast Ethernet Interface to prevent the burst of traffic from eating up the CPU?

I am having an issue with Cisco 1812j Router.
I have 2 1812j router. One router I accidentally lost the password so I reset the password as following link. [URL]
After that I could not submit "dialer" command. Like this.
c1812j-01(config)#int bri0c1812j-01(config-if)#d?dampening default delay descriptiondot1q dot1x down-when-looped dxi
c1812j-01(config-if)#
There is no choice to use "dialer" command.
The other Router is as below which looks ok.
c1812j-02(config)#int bri0c1812j-02(config-if)#d?dampening default delay descriptiondialer dialer-group dot1q dot1xdown-when-looped dxi
I guess I did something wrong to reset the unit.
I am trying to copy a setup from a Nortel IAX100 where the carrier provides two ATM PVC's over ADSL - one for voice (VoIP) and one for data (IP). Relevant lines from the backup of the IAX's configuration include the following for the PPP authentication over the voice circuit:
<wan_8_32>
<entry1 vccId="1" conId="1" name="Voice" protocol="PPPOE" encap="LLC" firewall="enable" nat="enable" igmp="disable" vlanId="-1" service="enable" instanceId="1509949441"/>
</wan_8_32>
<pppsrv_8_32>
<ppp_conId1 userName="" password="" serviceName="" idleTimeout="0" ipExt="disable" auth="auto" useStaticIpAddr="0" localIpAddr="255.255.255.255" />
</pppsrv_8_32>
The null username and password for the PPP connection have me a bit stumped. Does the PPP connection not use any authenetication at all? (Is that possible/likely? How could I deubg it?) Or does does the IAX100 supply a chap/pap response with null credentails? (If so, how would I duplicate that using an instruction to a dialer interface?I am configuring an 877 with 12.4T and advanced IP services.
To do this I’ve created another Dialer and re-assigned the atm interface (atm0/0/0) to it. Then I’ve done a shut and then a no shut a min or two later. To my surprise the debug ppp negotiation showed the user name from Dialer1 and then the line was back in my multi link bundle.
My relevant Config is below:

We have a dsl connection on 897 dsl router at the customers HO.The telephone line is directly connected to router we configured dialer with username and password and it takes a static ip of 212.249.213.xxx.Now he has some branches that are connected through wireless links and he has arranged for a subnet of 8 public IP's in the range 72.70.245.xxx
Can we some how use these public ip's as secondary in the routers dialer interface and assign to the servers in the branches so that it can be accessed through web.

View 33 Replies View RelatedI have a big problem with my Cisco 1841 and the WIC-1AM-V2 in Slot 0.I got the task, to test if it is possible, to build up a connection (Dial on Demand Routing) to a remote modem, which is connected to a console port of another Cisco 1841, with the integrated modem card over POTS from the CLI of the router. My router will only dial out to the remote modems and only if its needed.I am connected to the router with the integrated modem card over a console cable on the console port. The remote modem is also connected to the console port of the remote Cisco 1841.
I found out, with my Dialer Profile configuration, it is possible to build up a connection. I configured a dialer list, that specifies that all ip traffic is permitted an interesting for my dialer interface. So a telnet or ping brings up my dialer, which brings up my Async interface. With the "show line" command, I can see that the TTY line, connected with the Async0/0/0 Interface is in use for 5 minutes, because of the "exec-timeout 5 0", which is configured on the remote router. Now the problem is, in this 5 minutes, I can not use a remote telnet on this line with my loopback interface, because the line is already in use and I get a "connection refused". The first telnet I use runs in a timeout, because the remote host is not responding. When I dial out directly from the modem card and not from the CLI with the AT-commands, I get also the connection and with a return i get the login prompt. I will post my actual config, so that you can see maybe a mistake I did or which command I must use, to get a working connection. [code]
