Cisco :: Configuring Static Routing
Jul 30, 2012
Configuring static routing, how can i get a ping to go through a diff. route depending which host pinged? I want to ping host B from host A. Host A is connected to router1, which is connected to 2 other routers, router2 and router3. On the other end, routers 2 & 3 meet router4. Like a diamond topology. So basically routers 2 & 3 lead to the same place, router4, which is connected to host B. I need to configure static routing so that when I ping host B from A, both ping request and ping reply go through router1, 2, 4, host B, and back. THEN the part I dont understand, doing it the other way around: When I ping host A from host B, how can I get both ping request and ping reply to go through router4, THEN THROUGH ROUTER 3, then router1, then A, and back again to host B?

We upgrade our Internet service in our India office which required a new router. The local vendor suggested an 1841, so that is what we have. It has two fastethernet ports on it.
The ISP (Airtel) provided the following IP address information:
Public WAN IP : 122.181.23.200/30
WAN IP : 122.181.23.202SUBNET MASK : 255.255.255.252GATEWAY : 122.181.23.201Pri DNS : 125.22.47.125Sec DNS : 202.56.250.5

I am trying to configure a Cisco 871 router.There are 3 servers on my network that need static public IPs but also still need to communicate on the local network.I have given my WAN interface the first IP in the block and set up PAT for the rest of the computers on the network with that IP which is working fine. Next I set up static NAT rules for the servers translating 3 of the remaining public IPs to the internal addresses of the servers.I can access those servers internally using the public IPs but not from outside the network. A traceroute from outside the network gets dropped when it gets to my ISP.I've never configured more than one static ip for a network before and i know i've just missed a step here. Do I also need to use static routes? Will that update the next hop's routing table? Do I need to make an ACL to permit any host to the servers? If so, do I use the internal or external address?

I'm trying to configure intervlan routing between a cisco 2801 router and HP/Amer switches. Using int fa0/1 and subinterfaces I was sure I had it configured correctly, but I cannot ping the default gateways when I place a host in a particular vlan. Below is what I have configured.
HP switch - port 9 connects to fa0/1 on 2801
ip default-gateway 10.1.100.1
trunk 9 Trk1 trunk
trunk 10 Trk2 trunk - to another switch
[code].....

I tried the "Advanced Routing" Feature over the RV-042 V3 Dual WAN VPN Router , And the New IP Subnet i added ( 10.0.7.0 ) in the Static Routing Table does NOT Appear in the Routing Table of the Router. Please review the attached Print Screen for both the Static Routing Entry Configuration & the Routing Table of the RV-042 Router.

I have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.

Two Cisco C2960G Switches connected with each other using an EtherChannel Trunk Ports.IOS Image has been upgraded to c2960-lanbasek9-mz. 122- 58.SE2.bin.The global command "sdm prefer lanbase-routing" has been executed to set the default template to "lanbase-routing".The global command "ip routing" has been executed to enable the ip routing.An IP route has been configured in each switch to point to each other for the static routing purpose (Please see the 2 attached configuration files) The hosts in VLAN 111 and VLAN 110 are not able to see each other even the ip static routes have been configured.May be I have misconfigured some settings but not sure what's the actual problem.

Configuring an application using routing mode on cisco ace clients ---asa--3750--cisco ace--- servers behind vip,visa card transaction servers.i am able to setup a vip on ace using routing mode on ACE,as the servers need to see the client ip ,so we are not performing SNAT,this part is working fine,when a request comes from the client ,it goes to the vip and to one of the backend servers ,and the request will be forwaded back to the ace ,as the default gateway on the servers is pointing to the server vlan on ace.but if the transaction from the servers need to go to the visa card transaction servers ,how can we achieve this ,and after fetching the data from visa servers,does the reply will be fwd to the ACE or ASAs directly.

I currently have a Cisco 891 running with a FTP running on port 21. I currently have the NAT from external IP to and internal IP 192.168.12.6 for port 21. And the firewall allowing that traffic through and client software is working fine. However I need this FTP to be running on port 990 and anytime I change the NAT and the firewall, the external FTP clients connect but then drop when recieving the directory listing.

2. Via the Networking > LAN (Local Network) > DHCP Lease Clients I can thick a Lease and click on Make Static IP. The result is an error: Operation failed.

getting a SF300 to properly route IP between 2 VLANs. I've watched the demo video and performed everything it showed, but I get the most bizarre half-way results. I haven't done anything on Cisco routers in about 15 years, so I'm a little rusty.
We have an office LAN with a cable modem/router for Internet access where the modem/router has IP address 192.168.1.1. We have the usual 24 bit prefix net mask. The SF 300 is connected to this network on port 1.
I have configured port 1 to VLAN 1, interface in Access mode, assigned a static IP address of 192.168.1.36, which is a free address on our office LAN. I have configured port 2 to VLAN 2, interface in Access mode, assigned a static IP address of 192.168.3.1 I put a static route in the modem/router, pointing 192.168.3.0/24 to 192.168.1.36.
I have a PC on 192.168.3.10 attached to port 2.
The SF300 can ping 192.168.3.1, but not 192.168.3.10. 192.168.3.10 can ping 192.168.3.1. It can also ping 192.168.1.1, and can pull up an HTTP router admin page from 192.168.1.1. 192.168.3.1 can be pinged from anywhere on 192.168.1.x, but 192.168.3.10 cannot be pinged from 192.168.1.x. Finally, 192.168.3.10 cannot ping any other addresses on 192.168.1.x except 192.168.1.1, and cannot reach the Internet.
Here's my configuration:
switch6d919d#show runconfig-file-headerswitch6d919dv1.3.0.59 / R750_NIK_1_3_647_260CLI v1.0set system mode router

I'm looking for some input on configuring vPC on the Nexus 3048.I know that it's supported to use 1G interfaces for the vPC Peer-Link, but using 2x1G for the Peer-Link would make the Peer-Link a bottle-neck if the 10G ports are used in a vPC. What about using 2x10G ports for the Peer-Link and using the remaining 10G ports in one, or potentially two vPCs. Should that work or is it in any way not recommended? The reason I'm asking is that the 10G ports are called "Uplink" ports in the data sheets for the 3048.
We are planning to connect some servers to the 3048s using vPC with each server connected by 4x1G interface (2x1G for each switch), and then we want to connect a Netapp storage system with two controllers using 2x10G each (the controllers are active/passive, so you can think of it as two separate systems). We would connect controller A with vPC 1x10G to each switch, and controller B in the same way with vPC 1x10G to each switch.

I am about to configure 4 Gig ports for EtherChannel. I've been reading about EtherChannel and it seems easy enough to configure. I have a host (server)which I am going to connect to these 4 - gig ports. This is new for me and would like some feedback for those that have used EtherChannel on their layer 2 switches. The gig ports will be an access port with VLAN XX.

Configuring OSPFv2 on a Nexus 5K switches, after configuring area 0 or area 10 it shows as 0.0.0.0 or 0.0.0.10 instead, I'm planning to uplink a couple of ASAs with OSPF enabled, just wondering if the area format showing will be a problem, is this how is supposed to look in the Nexus 5K? and will the 5K be able to form adjacensies with other non-Nexus devices that have area 0 and 10?

getting radius to work on a 2950G switch with an older IOS of 12.1(22)EA1. I have radius setup on a windows 2k8 box and all of my other switches 2960's and above have no issues. I am unable to input the nas-identifier of 32 into the config using - radius-server 32 attribute 32 include-in-access-req format %h as well as the aaa session-id common commands. Doing a debug radius says that the radius server is not defined.

We're trying to configure our Cisco 4507 (Supervisor Engine IV) to allow a new Dell server with a pair of Broadcom 5708 GigE NIC's to aggregate its NIC's to give us a 2gbps link to the switch.
So far we seem to have got the team and LACP up and enabled, but the adaptor that the Broadcom Admin Util creates for the team is only showing a 1gbps connection where I would have expected it to show as 2gbps.
The individual NICs show as connected at 1gbps. We're not Cisco experts so are struggling on how to get the 2 NICs to aggregate.
On the server side we've done nothing other than create a team using 802.3ad LINk Aggregation using LACP.
This is what I think the relevent output from "sho conf" is, more available if needed.

We just received a new C2911 G2 ISR and have been trying to configure the EtherSwitch SM-ES2-24-P module on it. Through the router console, I tried assigning an IP address to the router Gi1/1 interface which I assume is the link to the Etherswitch module but all I'm getting is "IP addresses may not be configured on L2 links" - as per the docs, I should be able to assign an IP address on that "logical" interface link. Any other way for me to configure the ports on that switch module?

I want to configure management for some Nexus 5548's?I wanted to manage the switches via an SVI. I have read the following document which gives details about the Management SVI but doesn't answer all questions.[URL]I am not running any layer 3 functionality on the switch, no layer3 license (which it mentions in the above link) Will I still be able to create a management SVI. I know I will need to enable the feature 'interface-vlan' to setup a Management SVI, does that require a license?

We have 2x WS-C3560X-48 with the 10Gb SFP C3KX-NM-10G module.I want to use the 10Gb SFP (with a redundant 1Gb link) between each of the switches.Below is the configuration what I think I should use. Is this correct?
SWITCH1
int TE1/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
[code]....
We also want to utilise Link Agrrigation for the servers that attach to the switch. Would this config be correct?
port-channel load-balance src-ip
int range x
switchport mode access
switchport access vlan 1 (They are all on the default vlan)
spanning-tree portfast
channel-group x mode active
(Then I would configure the LACP config on the server) Is there anything I am missing?

I have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.
