Cisco WAN :: 2811 - External IP Not Pingable From Outside

Apr 20, 2013

We have a cisco 2811 router with 2 ADSL interfaces. One dialer interface is used for internet and another dialer interface is used for VPN.
 
The dialer interface that is used for internet purpose is "Dialer 1" and the VPN is "Dialer 2".
 
The route looks like this: ip route 0.0.0.0 0.0.0.0 dialer 1
 
Basically, I am able to the ping the external IP address associated with the Dialer 1 interface, however, I cannot ping the external IP address associated with Dialer 2.

Cisco WAN :: 7606 - Self IP Of Interface Not Pingable

May 1, 2012

I have an Internet Gateway with dual homed to 2 ISP's terminated in 2 different routers in my end. My end routers are 7606 routers.
 
I have a WAN link from Router 1 to ISP1 and from Router 2 to ISP2.
 
Router 1:
-------------
int Gi1/1
description " Link to ISP1"
ip address x.x.x.142 255.255.255.252
 
x.x.x.141 is configured in ISP end router.
 
The problem I m facing is that I m not able to ping x.x.x.142 from this router. But x.x.x.141 is pingable.
 
Also when I check from any internet route server, I m able to ping both x.x.x.142 and x.x.x.141.

Cisco VPN :: 1811 - GRE Tunnels Up / Up But Not Pingable

Jul 17, 2012

I am having an issue where the GRE tunnels are up/up but are not pingable. The GRE tunnels are on a cisco 1811 and cisco 2811 routers  The tunnel source and destination IP addresses are private  addresses. These private addresses are pingable to each other and they are connected via IPSEC. The IPSEC tunnels are generated from the ASA to which the cisco routers connect. Probably the tunnels are up/up because keepalives are not configured. But I am still not able to see why I cnt ping the end points. The ACL for IPSEC in ASA includes the "permit gre host <Private IP 1> hist <Private IP 2>" commands.

Cisco WAN :: Cannot Reach 1841 On Subnet / Other Devices Are Pingable

An 1841 is conencted to the internet by DSL, it works fine. I have added it to the 10.98.8.x subnet off a 3750 switch.When I connect other devices to the same switch port, I can ping/browse to them fine, but when I connect the 1841 I can only ping it from the 3750, not another subnet connected to the same router.

Cisco Switching/Routing :: WCL2112 / Wireless LAN Controller Not Pingable When Plugged Into Trunk Port?

Aug 27, 2012

I have a Cisco Wireless LAN Controller WCL2112 model. It's currently plugged into an HP Procurve switch on a trunk port. That HP switch is plugged into my Cisco stack on a trunk port. I can reach the WCL just fine through the LAN. But when I plug the WCL directly into the Cisco stack on a trunk port, I can't reach the WCL at all, unless I connect to it over wireless. The interface shows it's conneccted and up/up. But no communications are sent across the line. I did a wireshark and can see only ARP request from the WCL. The trunk port on the stack is set to:
                 
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport mode trunk 
 
The WCL has 3 VLAN's on it and the SSID of VLAN 1 is our office wireless. If that matters. .The Cisco Stack is 4 switches. cisco WS-C3750X-48P

Sep 19, 2012

My setup is ISP-2811-PIX 515E-LAN. Right now, I am doing a PAT for IPSEC tunnels to terminate on the PIX. Do you recommend I use the 2811 instead of PIX for VPN or keep things the way it is? Trying to determine the best box to use.

I have a particular site that is causing me trouble, this site is connected in a back to back configuration using 2811 at CO and 2621XM at CPE.  The CO end is also the CO for 3 other sites so has a total of 4 wics installed (WIC-1SHDSL-v2), these other sites also have 2621XMs for the CPE.
 
The problem i am getting is when one site in particular transfers large files to/from client machines, the CPU on the 2811 jumps to 99%:

While i know I can move most of the config unto the ASA, i know that the CME cannot be moved, hence I would like to do the setup such that users on the network still have access to CME.

Cisco :: Setup NTP Server Using 2811?

Sep 30, 2012

I've setup a NTP service by using Cisco 2811 routers. This works fine at the moment, but in the end there are some questions left.
 
1. I'm using two 2811 Routers, one for primary, which is resceiving the time from PUBLIC NTP 1, and one for backup, which is resceiving the time from PUBLIC NTP 2. Is it possible to compare these to times an check if the match? And if not, generate an alarm via e.g. SNMP
 
2. Is it possible to check via SNMP, if the routers are reaching PUBLIC NTP 1 and PUBLIC NTP 2 for sync?

Cisco WAN :: 2811 DSL Load Balancing

Dec 9, 2010

I have a Cisco 2811 router with two HWIC-ADSL cards configured for dsl connection. I have two lines from the same ISP and i am load balancing between them. I have created a couple of SLA's to check the state of the connections and add to the routing table the two default routes if both are up or any one of them is up.My problem is that when i  try to download big files (especially antivirus updates) the download at some point stops (especially the antivirus exits with an error of unreachability). If i shut down one line everything works fine.Could i use something (configuration-wise) to prevent this problem from happening?????Is there any way i can combine the two lines? They are simple ADSL connctions with static ip's.

Cisco WAN :: 2811 High Cpu Utilization

Apr 29, 2013

I have a 2811 that is really hitting the CPU hard.  Nothing shows on CPU processes.  It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN.  The HQ has 2-3 IPsec tunnels to other remote sites.  The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%.  The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps.  I read somewhere that its possible that fragmentation could be causing this.  My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites?  Siince they use the same outside interface to my HQ, is that correct?

Cisco WAN :: 2811 - Allocate CPU To Certain Processes?

Apr 23, 2013

Is there a way to allocate CPU or memory resources to specific processes - similar to a QoS-style configuration where you can prioritize the processes being handled by the CPU? We have a 2811 router whose CPU periodically spikes to 100% utilization. At these times, all of our EIGRP neighbor adjacencies bounce - either a peer goodbye is received or the hold time expires.
 
Our thinking is that we could possibly tell the router to prioritize the EIGRP process with the CPU so that routing is maintained, even though we realize other processes (like qos or ISAKMP for our tunnels) may suffer.
