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 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 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 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

Our Router  7606 is in a problem with high CPU Utilization. We are using one EBGP  and one IBGP session. We are also running OSPF with area 0 between two  IBGP router to exchange few local networks.

Cisco VPN :: Installing SPA-IPSEC-2G On 7606-S

Mar 18, 2011

I was trying to install a SPA-IPSEC-2G on 7606-S chassis. I installed the SPI/SPA cards in slot 3, after that I checked with "sh module"  and we could see the module "OK". After this we tried to configure a VPN tunnel but we received messages in the other router about "no ipsec package".
 
I was checking and I tried "sh crypto engine accelerator statistic"  and we got the message:   " There is no crypto device".
 
I don't know about installation commands in references and I don't know about restrictions or configuration modes.

Cisco WAN :: Which IOS Is For Router 7606 To Accept FWSM

Nov 10, 2011

I need to put a FWSM and a line card WS-X6148A-GE-TX to a router 7606. The FWSM version is 3.2(13). The router is running IOS 12.1(18)SXD3. The Cisco document here says the required IOS for router 7606 is 12.2(18)SXF or higher. I have downloaded the IOS 12.2(33)SRD4 and loaded it to the flash card. When I turn the router on, it doesn't load the new IOS and goes to rommon. Which IOS I should use to make the router 7606 work and accept the FWSM.

Cisco Infrastructure :: PPPOE Gig Subinterface - 15.2S 7606-S

Nov 5, 2012

We have an environment where we terminate our DSL customers over PPPoE on a 7606-S MPLS PE router with RSP720. The PPPoE sessions are terminated on a GIG V2 interface of a SIP-400. Currently the IOS running on the device is c7600rsp72043_rp-ADVIPSERVICESK9-M, Version 12.2(33)SRD. The following is the current configuration used.
 
bba-group pppoe 7virtual-template 7
 
interface GigabitEthernet2/1/3.142647 accessencapsulation dot1Q 14 second-dot1q 2647pppoe enable group 7
 
interface Virtual-Template7 ip vrf forwarding TESTip address 10.10.10.1 255.255.255.252
 
In the  above scenario everything works well.
 
However we had to upgrade the router IOS to    15.2(4)S Advance IPServicesk9 to support 4-byte ASN. After the upgrading we observed certain commands used to terminate PPPoE on the sub-interfaces not available on 15.2(4)S , although  PPPoE on Gig and Ethernet with QinQ support is listed under 15.2S feature set.

I'm sure I could add an ACL to block communications to my router based on this ports but would rather figure out how to close 'em so this already overloaded router doesn't have additional processing.
