Cisco Switching/Routing :: 2800 Series To Set Static Routes Per Vlan

Aug 3, 2012

Is there a way to set static routes per VLAN?Example VLAN 100 sends all traffic to and VLAN 200 sends all traffic to (2800 Series RTR)I have 5 networks that have their own gateway to the Internet via satellite link. Those networks run over the same infrastructure on separate VLANs. They frequently send traffic to each other, which gets sent over a slow SAT link. I introduced a router to the network and would like to set all my hosts default gateway to the local routers sub-interface then have a static route that send all traffic that is not on one of my 5 networks back to that VLANs respective SAT modem to get routed out over the Internet.

Cisco Switching/Routing :: 2800 Series VPN And PCI Compliance

Aug 21, 2012

I'm trying to turn off SSH version 1 & 2 to pass PCI compliance. Problem is, I cannot touch the VPN link between the two offices. I'm afraid the PKI certificate used for the VPN will be deleted if i zeroize the RSA key which seems to be the only way to stop the router responding on port 22. 
Here is the stuff from the running config related to the crypto map: 
crypto isakmp policy 1
encr 3des
authentication pre-share
group 2
[ code].....
I'm only CCNA so I'm not even sure if the certificate or RSA key is being used for the VPN link, but I can't tell from the running config that zeroizing it would be a good idea and not break the VPN. I'm open to other ways of disabling SSH, as we are able to just connect using a console cable. But it looks like denying port 22 with an access-list doesn't even stop the router from responding to the port.

Cisco Switching/Routing :: SG300 Static Routes Are Not Deleted / Editable

May 14, 2013

I have a Routing issue with one of my SG300-28P units. It has several Trunked VLANs. I think I habe Narrowed it down to a Default Route on the offending SG300 though I cannot see to change or delete any of the Static Routes on the unit. I can Add Routes with no issues, but once Added I cannot Edit or delete them.

Cisco Switching/Routing :: Module To Add Gig Interfaces To 2800 Series Router

Aug 16, 2012

I am trying to add WCCP to be configured for websense. My first option seems to be either purchase an IPServices license for the stack of 3750E switches, but i am thinking this will require us to license all three switches in the stack. The second option i am looking at is to do the WCCP configuration on the 2800 router we have on the edge. The problem is both Gig ports are in use, one going to the firewall and the second going to the ISP. My first question would be, which option is better in terms of manging as well as cost of implementing it.The second question is, if WCCP on the router is a better option, what is the add on module i should be looking to get to add the additional ports to hook up the Websense cache.

Cisco Switching/Routing :: 2800 Series - Dual ADSL Links?

Jan 31, 2012

In a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?

Cisco Switching/Routing :: 877W - Multiple Static Routes / Same Destination Dialer0 And Vlan1?

Jun 10, 2013

Is there any way to have my Cisco 877W Router alter from using one static route to another static route when another router on the network is reporting destination host unreachable?
Router 1 (
Dialer0 -> ppoe to internet
Vlan1 -> local
 Router 2 (
Dialer0 -> ppoe to managed VPN (
Vlan1 -> local
Router 2 is connected to another network through a managed VPN and that network also has internet access. I want to be able to have two routes to the internet on Router 2. And when Router 1 internet goes down packets get routed through the VPN instead.
I currently have on Router 2
ip route
ip route Dialer0
ip route 250
Which does nothing when Router 1 has its Dialer0 interface shutdown, or goes offline completely.I suspect I could reverse the setup and have everything routed through the VPN by default and then if / when Dialer0 interface goes down it would switch to using Router 2, but if the problem is in the remote network and interface Dialer0 stays up, it would probably do the same thing... nothing.All devices mentioned are Cisco 877W routers with ADSL and a bunch of fast ethernet interfaces.

Cisco Switching/Routing :: 2800 Series Router - Multicasting Windows Deployment Services

Mar 25, 2012

We have recently implemented Windows Deployment Services on our local network, but everytime we do a multicast image deployment the network get flooded to point of total saturation.
We have Netgear switches and a Cisco 2800 series router. IGMP Snooping has been enabled on all Switches, however, we are unsure on how to implement multicasting on the router.
The whole network is flat - no VLANs over than the default VLAN1. We only want multicasting to work within our local network and does not need to go out the other side of the router as that is the connection to the internet.

How to get the Cisco router configured properly to enable multicasting to not flood the network. It seems that even if we were to image 4 PCs using multicast this is enough to completely get the network flooded.
Also, am I right in thinking that IGMP needs to be enabled on all of the Switches?

Cisco Routers :: RV180 - Subnet Calculation In Static Routes And Routing Table

Jan 3, 2013

I've been playing around with the Cisco RV180s for a while now and have come across a problem with the subnet calculation in the static routes and routing table. Essentially, if I configure up a static route for a /16 it's entered in the routing table as a /13. If I add a /24 it's entered in the routing table as a /16. I haven't tested every subnet size and combinations but this looks like a fairly fundamental maths bug.
As a side note, I notice that the release notes state the removal of SSH Server, however, I can not find any reference to it's existance prior to, did/does it exist in and if so where? .
Screenshots are below and an extract from the configuration file for reference.

From the config file:
route = {}
route[1] = {}
route[1]["active"] = "1"
route[1]["dstIpAddr"] = ""
route[1]["gwIpAddr"] = "

Cisco VPN :: ASA 8.4(3) Dynamic VPN And Static Routes?

May 20, 2012

I am running an ASA with 8.4(3) and am trying to setup a dynamic VPN tunnel.  We are having a business reason to establish a VPN tunnel to customers who do not have nailed down IP addresses.  Now I found a number of documents that outline the steps involved.  It seems the basic steps were to Establish a regular tunnelAdd dynamic crypto mapAssign the dynamic crypto map to the tunnel created under step 1. While this sounds pretty straight forward and simple, while prepping for doing just this I hot a road block while thinking it through. In order for my ASA to put anything into the tunnel it has to have a route to the remote network pointing at my VPN peer at the  end of the tunnel.  How do I do this in a dynamic tunnel?  How do I add a dynamic route so the ASA knows which tunnel to stuff the traffic into?  How do I stop the traffic from just being send to the Internet?

Cisco WAN :: 1841 Floating Static Routes Configured If DSL Link Goes Down

Sep 19, 2011

I am having some trouble configuring dual NAT on a Cisco 1841.
The 1841 has three interfaces.
Fa0/0 - LAN
Fa0/1- Different private network
Fa0/1/0 - Connection to DSL modem
NAT overloading is configured on Fa0/1 and we have traffic that must be router there. We would like to have all internet access go through the DSL modem. Currently internet access is obtained through fa0/1 but is not ideal. I have floating static routes configured if the DSL link goes down. (Which is currently unplugged) I do not have physical access to the router at this moment. We would like to keep the config a simple as possible. It seems like route-maps may be one of our only options.
