Cisco :: BGP And Default Gateway 50% Loss Between Hosts

Mar 22, 2013

Why it makes problems to use a default route on a BGP-router (cisco 6500 with sup720 3bxl).Only a very few amount of hosts have that kind of problem and the 50% paket loss is only between this hosts. So another host has no loss to any of the affected hosts. looks for me like there is a problem in the CEF-table.The router has a BGP-fulltable. The gateway of last resort is only set for cases like a flapping BGP-route, so that the traffic is sent to a default next hop, because sometimes he knows a better route which isnt flapping.

Cisco Routers :: How To Manage Port 80 Hosts Via Gateway To Gateway VPN (rv220w)

Aug 30, 2012

I replace our aging rv082 routers with wireless rv220w routers. The gateway to gateway vpn works great, however I am no longer able to manage our print servers port 80 management page. I can ping any host with success, and I can manage hosts that have a port 10000 or 8000 web interface - but no port 80 ones... I had no issues when using the old rv082 routers...

Cisco Switching/Routing :: C6509 Loss Of Packets ICMP Sent By Different Hosts In Different VLAN

Oct 17, 2012

I've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
When I send consecutive ping message I  found always a missing of packets . Furthermore When I insert the  "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.

Cisco Switching/Routing :: 1841 - Unable To Ping Remote Gateway Or Hosts On Other Side Of Router

May 30, 2012

I am just setting up a simple scenario with a 1841. Server @ cannot ping or It can ping The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.

Default Gateway Not Available

May 3, 2012

Periodically, I drop internet everywhere around my college's campus. I'm literally four feet from a router, but it doesn't seem to matter. I'll disconnect, run troubleshooter, and I'll get the error message saying that the default gateway is not available. My college is designed for Macs, but I'm running Windows 7. My Mac colleagues do not experience problems. The computer works at home and at nearly every other wireless network I've brought it in range of. Specifically, either IBM or Dell.

Dell XPS 15
8gb Ram
Windows 7 Home Premium SP 1
540? Something around 500 Nvidia graphics card

Default Gateway Is Not Available?

Nov 30, 2011

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]

Cisco :: ASA 5505 As Default-Gateway?

Mar 28, 2012

I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?

Cisco WAN :: Can't Use ASA5505 As Default Gateway For LAN

Mar 16, 2011

We have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?

Default Gateway Came Up Empty

Feb 8, 2013

I am having issues playing certain games on my ps3. So I've been searching for solutions and I came across a video that wanted me to go to run/cmd/ipconfig. I have little knowledge of computers but I'm not sure that what my ipconfig is showing is supposed to be there. At first I googled and learned about ipv6 addresses because i found that weird but i think that checks out fine. I then googled about the weird numbers and letters in my default gateway and came up empty. Is there a reason thats there?

No Internet Or Default Gateway

May 8, 2011

Basically, I'm using a broadband modem, which appears to be connecting fine, with all the required lights being on. My ISP says that, from their end, everything is perfect. Even my laptop shows Local Area Network as connected.However, for some reason, I am not able to access the internet. I was able to use it till last evening, but suddenly the internet stopped working. On Google Chrome, it says that there is no DNS or something.Subsequently, when I tried to access my modem settings, it shows as 'webpage not available'. I then noticed that there is no default gateway! I was able to access it the day before, but now I can't.

Cisco :: Default - Gateway On Switch Command

Mar 27, 2013

I'm really not clear about default-gateway on switch command, not the function but how its works.i have 1 multilayer switch (MLS 1) that have 2 vlan within it, vlan 2 and 100. on vlan 2 i assign ip address of and on vlan 100 is both vlans are up. then under that multilayer switch i added 2 more MLS (MLS 2 and MLS 3), and the links of MLS 2 and 3 to MLS 1 are trunking. and both MLS 2 and 3 have a same vlan with MLS 1. that i assign an ip address on vlan 2 in MLS 2 and i set default gateway, and i do the same to MLS 3 but the ip address of vlan 2 is already setup the routing protocol on MLS 1 so that vlan 2 could contact vlan 100. but the fact it doesnt work at all, both MLS 2 and 3 cannot contact vlan 100 eventhough that are already have default-gateway setup, is there anything wrong with the configuration ??

Cisco VPN :: 5510 - ASA 8.4.(1) VPN L2L Can Only Be Established Through Default Gateway

Jun 19, 2011

We have an ASA 5510, with two internet connections. One inteded for VPN l2l and the other for general users inet access.

On asa 8.04, I configured the crypto map on inteface "VPNAccess" and a static route to the L2L remote peer through VPN internet access, the default rotue was pointing the general inet router.
We bought a new firewall with 8.4.1, and now asa only tries to initiate traffic if remote peer is on the default gateway.
It ignores more specific routes (i mean longer masks) and always tries to use default gateway, but only for VPN, if I make a trace route for that peers it uses correctly the routing table.

Cisco VPN :: Tunnel Between 2 ASA 5505s With Same Default Gateway?

Is it possible to create a site-to-site ipsec vpn (lab environment) between two 5505's (ASA IOS 8.2(5) & asdm-645-206) with the same default gateway. I.E. a back to back site-to-site VPN tunnel or do I need to deploy a router and hang each 5505 off a different interface? We have plenty of public IP's but only one default gateway to our ISP (Internet).

Change The Default Gateway Of RDP On Server?

Oct 11, 2011

I rdp into our server 2008 via IP. This is a router on ip 0.1, this is forwarded to my server on IP 0.3. This server was setup with DHCP default gateway of 0.1. We added a new outside connection on IP 0.2. I was talked through the changes so that internal DHCP requests went to gateway IP 0.2 but RDP still used 0.1. I plan on getting rid of 0.1.Where is the setting to change the RDP to use default gateway of 0.2?

Default Gateway Is Unavailable For Laptop

Jan 15, 2013

I've been trying to connect to the internet all day. Every time it connects, but only with limited connectivity. I run troubleshooting, but it doesn't fix the problem. Sometimes it won't have anything to report back other times it says that the default gateway is unavailable. My laptop is the only device in our home that won't connect, so I don't think it's the router.I think the router is a cisco router, there is a cisco box mounted on the ceiling with a cord leading into it (I don't have access to any buttons though)I live in an apartment building with free internet, so I'm not sure who the provider is.

Media Disconnected And Default Gateway Not Available

Dec 28, 2012

I had problems connecting to my wireless internet for extended periods of time with my lease expiring almost instantly. Nobody else in my house had trouble connecting, only me. Troubleshooting the connection only showed that the default gateway was not available and failed to allow me to connect despite "fixing" the problem. I attempted the ipconfig/renew, netsh int ip reset reset.log, and netsh winsock reset catalog operations in cmd as an administrator to no avail. Finally, as a last resort, I reset my modem and that finally allowed me to connect although occasionally I would be kicked off the connection and have to restart the modem again. I would still like to know the problem and a possible solution since my friends seem to have a similar problem with their wireless internet.

ipconfig/all before resetting the modem:

No Connection Via Ethernet No Default Gateway?

Jul 3, 2011

I got a hand-me-down laptop the other day. Wireless (WLAN) works fine, but I can not connect via ethernet.

It gives the "Limited or no connectivity" message, even if the ethernet cable is unplugged (no "a cable has been unplugged" message)

The laptop is plugged in to an EWIRE modem/router. Desktop connects fine via ethernet, as does my PlayStation 3 console via wireless. So I don't think it has to do with the modem/router. It's a Compaq from 2005 or so. Windows XP Pro SP3.

Microsoft Windows XP
Media Center Edition


I have a general knowledge of fixing the typical internet connection problem (obtain DNS automatically, repair connection, unplug modem for 20 seconds, etc) but I've never been this stumped before.
