Cisco Switching/Routing :: 1002 ASR Sometimes Vlan User Will Not Be Able To Access
Apr 2, 2013We are having Cisco router 1002 ASR and 2841 switch. Some times perticular VLAN user will not be able to access the network but from the same switch others VLAN users can able to access. We were getting ARP entries in router but we cannot ping the IP's. Even we clear the ARP entries. Once we restart the switch users can access the network. We have changed vlan ports, uplink too. but problem not solved. and we observed CPU utilization will be going 70-80% some times and at same time switch hangs.

Feb 4, 2013we are replacing network equipment at one of our sites. The network will have 12, 3750X switches(6 stacks) - one stack will be the core. A 1002 will be the WAN router to the Main campus. The 1002 will connect to the core via 2 ethernet cables. I'm debating whether to use L3 or L2 between the router and Core. I've heard that routing is more efficient if L3 is used and also I will be able to create an L3 etherchannel between the 1002 and Core switch. See the attached doc.

Feb 12, 2013I was asked to configure a new ASR 1002 today and after successfully puttintg the config on the router (via TFTP) the router will no longer communicate with anything. There is nothing in the config to cause this (it was actually pulled off a working production ASR 1002) and I am unable to ping a local loop back IP while consoled into the router?? I removed the config, reloaded the router and configured a new loop back - same issue cannot ping the loop back or anything else connected to this router.

Cisco Switching/Routing ::1002 Layer 3 Ether-channel Vs Two Separate Links
May 19, 2013We were going to create a 2 port, layer 3 etherchannel between a 1002 router and a 3750X layer 3 core switch. We wanted to create bunled link between them but, now we are going to be putting a Riverbed device between the router and core switch. Because of this, would it be best to abandon the idea of creating a layer 3 etherchannel and just have 2 links from the router and core switch and have traffic load balance between the 2 links?The Riverbed will have 2 connections into it from the Core switch and 2 connections into it from the 1002 router. I was hoping to keep the layer 3 etherchannel but, do you think it would be best to create 2, /29 nets and have the router/Riverbed and Core Switch/Riverbed load balance.

Jan 10, 2013I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

Jun 13, 2011I am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?
Cisco Switching/Routing :: Low Bandwidth On 3750 From Vlan To Vlan?
Nov 20, 2012We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP
IP Address:
Client: 172.16.2.10Vlan2: 172.16.2.1Vlan7: 172.16.7.1ASA: 172.16.7.2
I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:

Cisco WAN :: 1002 - ASR Not Doing Basic Routing
Dec 25, 2012I have 2 sub net directly connected to a ASR 1002. This is the configuration
interface GigabitEthernet0/0/0
ip address 193.145.14.114 255.255.255.252
negotiation auto
[Code] ....
The interface gi0/0/0 is connected directly to 193.147.14.113/30 in another router. And the Gi0/1/1 is connected to my internal infra structure. From my router I can ping 193.145.14.113 . So. I configure my PC with default-gateway 193.147.107.3 (ASR).
From my PC
I can ping 193.147.107.3 (gi 0/1/1)
I can ping 193.145.14.114 (gi 0/0/0)
But I can not ping 193.145.14.113 (the other point connected to gi0/0/0)
Why???? It is a IP inside of a sub net directly connected to the ASR. Why the ASR is not doing routing? ip routing is enable.

View 4 Replies View RelatedCisco Switching/Routing :: Multiple VLAN Routing Tables For 3750 Catalyst
Oct 24, 2012I have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?
View 2 Replies View RelatedCisco Switching/Routing :: Catalyst 3750 Multi-cast VLAN Routing
Oct 28, 2012I have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).

View 12 Replies View RelatedCisco Switching/Routing :: Inter VLAN Routing On N5548P Without L3 Daughter Cards
Jun 1, 2013I have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.
I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
Here some excerpts of what I´m saying:
PING results:
10000 packets transmitted, 10000 packets received, 0.00% packet loss
round-trip min/avg/max = 0.809/2.496/57.559 ms

Cisco Switching/Routing :: Inter-VLan Routing On Catalyst 3750 Switch
Dec 17, 2011I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
Cisco Switching/Routing :: 5505 Inter-vlan Routing With Multiple Gateways

We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
