Routers / Switches :: Separate Subnets Not Working As Described

Jun 25, 2011

I'm trying to set up 2 separate networks in my home, both of which have access to the internet through a single ISP.I have set up my networks using 2 routers as described in the "Version 2" scenario found here: url...The problem is, a computer connected to the LAN side of Router 2 is able to ping and map shared folders on computers connected to the LAN side of Router 1. According to the writeup (last paragraph), this should not be the case.I have been over the setup multiple times to ensure it is per the writeup but each time, I am able to ping and map.Is there some additional router/computer settings that I may be missing?FWIW, here's my take on what is happening (with the ping): When a computer on the LAN side of Router 2 (submet 192.168.1.x) does a ping to a computer on the LAN side of Router 1 (subnet 192.168.0.x), Router 2 sends the request to its Default Gateway (since it's a different subnet).Router 1 however, recognizes this as its LAN side subnet and forwards the request to that computer. The ping response is then routed back from Router 1 to Router 2.

Cisco Switching/Routing :: Two Subnets Through Pair Of SG200-08 Switches

Mar 21, 2012

I have two separate companys both with staff at two locations and thier own networks connected with a wireless antenna which provides a high speed LAN connection between offices.  I only have a single path through this antenna bridge.  I have an SG200-08 switch at each end.  What I am attempting to do is utlise the switches to take the two subnets at one office, combine them to one for transfer through the antenna bridge, and then resolve them into the two separate networks again at the other end.

Routers / Switches :: Why Can't Ping Computers On Separates Subnets

May 21, 2012

My new employer has asked me to determine any issues that could be causing performance issues our LAN. The network has two subnets and one of the first things that I noticed is that I cannot ping computers on subnet A from subnet B. I've looked into this and found a few things.-I CANNOT traceroute to computers on subnet B from subnet A-I CAN NMAP to computers on subnet B from subnet A-Computers on subnet A CAN ping other computers on subnet A and computers on subnet B CAN ping other computers on subnet B-Computers on subnet A CAN ping and access servers on subnet BI am relatively new to networking and not exactly sure where to start investigating this problem.

Cisco Switching/Routing :: Connecting 3570 Switches To Nexus 2232 To Migrate Server Subnets

Nov 17, 2011

I am in the process of migrating our existing server farm subnets to our new Nexus server farm and I discovered something I wasn’t expecting. My intention is to migrate our existing legacy server farm which is comprised of for paired 3750 switches off of our core 6509s and onto the Nexus and connect them to the 2232s via multi gig port-channel connections, two port channels per switch stack. 
 
NOTE this is expected to be a temporary move as next year we intend to install additional N2Ks and move servers over to these directly. But to minimize the outage/downtime it will be better to move the subnets and switchs all at once.
 
These connections would be grouped 1 gig connections as port channels, one from each switch into one of the two 2232s.
 
Problem I discovered is Cisco does not intend to have switches connected to the Nexus and it immediately disables the ports when they see BPDUs.
 
I found a config that does work and it does fail over from one port-channel connection to the other but with the limitation that when the original port channel comes back online it does not fail back over to the original one, an acceptable situation for us. But I am wondering if Cisco would support this design if we did experience issues down the road.
 
The only issue I really see is to get it to work the config is different on the two N5Ks, see the pert config below for the connections. Both are running the same OS

Cisco Switching/Routing :: Mix 10G And 1G Uplinks On 2960s?

May 16, 2013

Cisco :: Possible To Have Service Policy On Layer 2 Uplinks To Routers

Jan 10, 2013

I have the following scenario: Pair of Cisco 887VA routers acting as Layer 3 for Voice/Data VLANs with a pair of 2960 LAN Base switches acting as Cores and possibly then 2960 LAN Lites hanging off them as access switches. Our Service Provider has provided an example config where the class-maps match based on dscp values for the QOS policy applied to the DSL circuits. We can obviously trust the attached phones but I want to be able to mark data traffic on my core switches based on destination IP/port to allow application definition. My major question is can I have a service policy on my Layer 2 uplinks to the routers where the linked classes setting dscp vlaues are based on class-maps matching on the contents of IP access lists based while at the same time not remarking the EF marked packets from the phones?

Cisco Switching/Routing :: Nexus 5010 Interconnected With Two UpLinks

Dec 11, 2011

We are looking for some latency in our net and I am trying to check if our STP implementations is running correctly - we have a simple flat network here and no blocked ports here - just two nx 5010 which are interconnected with two uplinks.A remote site - mirrored setup - with 2 10G dark fiber connections - one for each nx5010 - is connection a DR site. I have split the two sites in two stp domains by enabling bpdu-filter on the vpc between the two sites.

I have been running wireshark on the local segment for some time and see the STP RST ROOT announcement every 2. seconds  - this is probably normal ? I was looking for some alternate root negotiation packets which would cause the mac tables to be flushed.

Cisco Switching/Routing :: 10 Gigabit Ethernet Uplinks 3750E To C3KX-NM-10G With 3750X

Jan 5, 2012

I need to connect one  sw3750E with   two  3750X  , with Uplinks at 10 GBps. My doubt is the next:
 
Switch 3750E  has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ????  the other SFP slot is disabled automatically?
 
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module  is considered, this will be connected to SW3750E by means of  SFP-H10GB-CU5M.
 
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.

Connection Between Two Subnets

Apr 12, 2012

I have a home network. There are a total of 3 PCs. Each runs Server 2008 32 bit. One PC - Lets say Server A has 2 NICs with Ip addresses, 10.0.0.10/30, 10.0.0.2/30. Other two computers Server B and Server C have single NIC with addresses 10.0.0.1/30 and 10.0.0.9/30 resp. So as you can see that there are two subnets 10.0.0.2 - 1 and 10.0.0.9 - 10. I can ping B and C from A. I want that B and C can also ping each other and if I run tracert on B or C, it should give me the route to the destination via A. All this without any other hardware. Like using route add... etc eg. if I write tracert 10.0.0.9 on B, it should return a route like 10.0.0.1-----10.0.0.10------10.0.0.9.

How To Connect Two Subnets

Mar 26, 2013

I have 2 DSL Lines going into a load balancing router. The load balancer is set up to distribute the traffic equally on the two lines, hence doubling the bandwidth. Though great at load balancing, it cannot handle DHCP for the 50+ users on our network, and therefore we are using another router for DHCP, which is running DD-WRT firmware.DSL 1 - 10.1.0.1DSL 2 - 10.2.0.1Load Balancer - external 10.1.0.2, 10.2.0.2 internal 192.168.10.1. DHCP Router - external 192.168.10.2, internal 192.168.1.1All other devices - 192.168.1.xThe load balancer has many options to direct traffic to one WAN port or the other based on IP address, which we would like to implement. But right now, since all my devices are on the 192.168.1.x subnet, it can't see anything but the DHCP router. So essentially it thinks it has only one client.

Cisco :: Designing A Network Using Subnets?

May 5, 2011

I recently added a post lately referring to drawing a topology of a large network with a high number of hosts. Now with project itself, I'm designing a network for a large organisation with a different number of hosts at each location.These are, 500,18,52,236 and 12. The location with 500 hosts is the head office, to which every other branch has a wide area network connection through a serial link.How many subnets would I require? I wrote down subnet details, but only for 5 subnets, a subnet for each location. Is that all I need? Or do the WAN connections count as subnets

Cisco :: Communication Between Subnets On 5510

Sep 13, 2011

I am working on a Cisco 5510 with multiple interfaces and requirements. I have experience with Cisco IOS, but not too much with the ASAs. I seem to be getting a bit confused on the NATing and ACLs on a firewall that was started by another employee, who is no longer here. With my current config I can get the firewall in place (we are currently using an older PIX) and most basic functions work except for two key things: 1) communication from the finance interface to the inside interface. The finance subnet has some restrictions that you will see in the ACL- we are trying to limit connections to the those systems, but they need to be able access an e-mail server on the inside. 2) communication from the DMZ interface to the inside interface. Maybe related to the first problem?

Cisco :: Multiple Public Subnets On Asa

Mar 2, 2012

I've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.

Cisco :: VPN Can't Access Subnets Behind 2nd Router

Mar 11, 2012

I purchased an ASA 5505 and placed it between my Cable Modem and Cisco 3745 router. The outside interface on the ASA is dhcp, the inside interface is 192.168.100.1. The outside interface of the 3745 is 192.168.100.2 and the inside is 192.168.1.1. The VPN pool is 192.168.200.10 - 192.168.200.10.

1. When I establish a VPN session to the ASA, I can ping and access any resources dierectly connected to the ASA's interfaces and on the ASA's internal 192.168.100.0 network. However, I cannot access any resources behind the 3745. I cannot even ping 192.168.1.1. Even directly connected hosts on the ASA cannot access Hosts in the 192.168.1.x subnet. There appears to be no traffic between 192.168.100.0 and 192.168.1.0.

2. Although I believe that I sent up split-tunnel, I cannot U-Turn back to the internet once connected to the VPN.

Here is my network topology as well as my ASA config and Router config.....

Cisco VPN :: ASA 5520 Not Processing RRI Subnets

Jun 18, 2012

I am coming to this forum because TAC and several CCIEs are having trouble finding me a solution to my problem.
I have Two 5520s each running 841 connected in two different data centers with two different internet providers. I have 100+ 5505s that have the capability to connect to either 5520 via EZVPN to either 5520. Up to now there has not been a need for a 5505 connected to one 5520 to talk to another 5505 on the other 5520. Each 5505 accesses network resources as in any enterprise network. Our company recently started telecommuting and I have been giving 5505s and a VOIP phone out to people. What was discovered is, if you are on one 5505 connected to a 5520 and the other 5505 is connected to the other 5520 the audio in voip does not work. If both the 5505s are connected to the same 5520 than everything works fine. Conversely a 5505 on one 5520 cannot ping a 5505 on the other 5520. 5505s on the same 5520 can ping each other no problem.
 
My problem: All 5505's are configured for a 172.18.xxx.xxx  255.255.255.224 subnet. This subnet is not used anywhere else. So I have a 100 Class "C" subnets carved up into 255.255.255.224 networks. If I look at a specific route for a subnet on one 5520 I see it pointed to the outside interface via RRI. I can look for the route in the 5520s connected CORE switch and I see the route pointed to the 5520. We have a fiber connection to the CORE in the other data center. The route is in this CORE switch as well. When I look for the route in the 5520 connected to this core it is not there. I have all other routes visible but not this particular route which should show on the inside interface. All I show on the 5520 are the 5505s connected to this ASA. So the 5520 is not processing the RRI subnets from the other 5520 and vise versa. Thats why a 5505 on one 5520 cannot ping a 5505 on the other 5520. I only see 172.18.0.0/27 on the outside interface of both 5520s. I do not see any 172.18.0.0/27  on the inside interface on either.
 
I have had numerous TAC cases open on this and no one seems to either understand my problem or have a solution for me. My local sales rep CCIE says the problem looks like a bug in 841 (which I am running) and that the ASA is not processing RRI from eigrp which I am running as well. The whole network is running the same instance of EIGRP including the 5520's.
 
My questions:
1) Is it possible the 5520 is not allowing 172.18.0.0/27  on both the outside and inside interface? Even though all subnets are masked proper the ASA maybe thinks it is being spoofed? I have not been able to confirm this using the real time log.
2) Could this really be a bug? I have looked at all the release notes and have not found anything resembling my problem. TAC has not recommended that I upgrade or downgrade my IOS.

How To Find Out Range Of Subnets For Given IP

Jul 7, 2011

if some gave me an IP address and subnet mask, and they told me to identify the range of valid subnets I have no clue how to do it. I know how to work out the total number of subnets and hosts, you just look at how many subnet bits have been borrowed and use the 2^ formula. For example with the IP 172.28.123.0/25 I know the default mask for a classs B address is 255.255.0.0/16 so in this example we have borrowed 9 subnet bits to give mask of 255.255.255.128/25 and 7 host bits remain. In order to find the total number of subnets you do, 2 to the power of 9 because we borrowed 9 bits, which tells us that there's 512 subnets and to find out how many hosts we do, 2 to the power of 7 because we have 7 host bits, so that gives us 128 hosts in each subnet. Now this is where I get lost, how do I find out the number of the first and last subnet? I know there's 512 subnets and each subnet has 128 hosts. But I don't know the number of each subnet, the range to be more precise. How do I workout the first, second, third, fourth etc subnet address

Connecting Two Subnets At Layer 2

Jul 2, 2012

I have :

- two different subnets (S1, S2)

- these subnets are connected to an IP backbone via wirelles acces points

I would like to physically connect these subnets together so the networks devices in S1 could directly communicate with the devices in S2 and vice versa without going through the backbone.

The obvious solution seems to interconnect these subnets with a router or a switch L3. But I would like to connect these subnets and stay at layer 2.

So, is it possible to connect S1 and S2 with a switch L2 ? If I do that, what is going to happen? Can I create just one subnet S3 from this two subnets when I connect them together and have my two separate subnets back as soon as I disconnect them?
