I have been playing around with Packet Tracer trying to understand EIGRP and to put it into practice. Well im not doing so well, I cant get the routers to form an adjacency therefore nothing is pinging outside of the routers. [URL]

View 5 Replies View RelatedI'm trying to set up a network comprised of three LANs connected by serial. As this is a small part of an assignment I've been instructed to subnet into /26 and to use /30 subnets for my serial connections.At the moment I can ping between devices on each of the LANs but I can't ping between routers at all. Embarrassingly I'm not sure why, I think it may be something I've missed on setting up the serial links as I have set routers up fine before using other connection types.

View 6 Replies View RelatedI'm an IT student and I've been assigned with homework simulating a network including an ISA server and some clients in Packet Tracer but I can't find anything which can be configured like an ISA (Internet Security and Acceleration) server(this is kind of Microsoft's technology as I know) in Packet Tracer, the generic Server from the devices box has only some basic services such as HTTP, DHCP, DNS, FTP, AAA, ... but none of anything related to ISA, all the servers in Packet Tracer have only 1 interface whereas the ISA server (as far as I know) should have at least two interfaces, and there is also no CLI supported for those servers so I think I can't simulate ISA server in Packet Tracer, can I?

View 4 Replies View RelatedI am unable to get traffic from any VLAN to communicate outside of the router, as well as get any traffic from outside of the router to communicate with any device on either VLAN. I am able to ping the router from each device on each VLAN, and vice versa. However, the traffic seems to die at the router, and I cannot figure out why. I know it's probably a small, easy fix, but I cannot seem to find any kind of documentation on it.

Is it an access list that is blocking the traffice or VPN setup.
View 5 Replies View RelatedI've been using packet-tracer for some time on and off with mixed results.
I'm running a multi context firewall with over 10 of the contexts sharing the same outside interface / network. All interfaces obviously have valid, unique IPs and also unique MAC addresses as mac-address auto is enabled in the system context.
This is an ASA 5550 running 8.3(2.10) interim so includes the fix for the well known packet-tracer classication failed bug.
So in theory, with firewall contexts on a shared interface the ASA should use the firewall MAC address to classify incoming traffic to the correct firewall and as far as I am aware, only fall back on using NAT to classify if the interface MACs are the same. In reality on my platform this doesn't seem to be happening and the classifier is using NAT to determine the destination context. I'm seeing this with live traffic (i.e. not generated by packet-tracer) in logs and can prove it by disabling certain NAT rules (there is some overlap with the IP addressing behind each firewall).
My question regarding packet tracer is this - in the above scenario with a shared outside interface, does packet tracer ALWAYS use NAT to determine the destination context? Or does packet tracer look up the MAC address of the ingress interface according to what context you are running packet tracer from? It appears that packet-tracer is using NAT in my case which could be just symptomatic of the potential bug I've described above rather than by design.
here, am used to the RouterSwitch CLI but been asked to set up an ASA 5505 8.4.Quite simply I am trying to at least test out a static PAT from an external source to an internal server in a test environment and no matter whether I set it up as an auto-nat or a twice-nat whenever I run a packet tracer I end up with the same error. This is the packet-tracer I am running-packet-trace input outside tcp 80.80.80.80 3389 10.240.0.10 3389

Now I have a couple of questions initially. I have made the presumption that packet-tracer does not look at any external devices while running - as in as long as the ports are up it doesn't matter what is on the end of them for testing purposes? Is there anything I am missing?I have this morning wiped the config and have simply set up the adapters, a default route and twice nat and am not sure why I keep getting the error. I am sure it is something very simple and I'm being a massive donut!

i have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

View 3 Replies View RelatedI was called into look at a customers's site that was upgraded by another vendor. They were complaining about packet loss and performance issues. I discovered they had changed from static routing and turned on EIGRP (100) and the EIGRP neighbors are not on a common subnet, they used secondary IP addressing to connect two 4506 switches to the core router. Correct me if I'm wrong, but won't this cause the neighbors to bounce and cause the degraded network performance? Don't we need to have a single common subnet for this to work? Either that or they have bridged the VLANs somehow? There is also a cable connecting the 4506 switches besides the uplink to the core router.

Router connects to ISP but cannot browse the Internet. I have updated the firmware to 2.0.3.2 and that did not work. Reset the router to factory settings and that did not work either. Router had worked until the ISP changed the ONT. The router worked initally after the ONT was changed, but that changed sometime during the day as it did not work that night. The ISP gave me a netgear router and that works, so I can connect, but I would rather the RVS4000 would work. I assume a setting at the ISP, but do not know which one. I get an error on the computer "name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded" I can ping, tracert and my little weather gadget works, but a web page will not display

View 1 Replies View Related We use all Cisco router in our business mostly 1841 and 871. But now i'm currently working with a new router:
Just purchased last week - Cisco 881
The Cisco IOS is:
Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.0(1)M6, RELEASE SOFTWARE (fc1)
->System image file is "flash:c880data-universalk9-mz.150-1.M6.bin"
As all our router are Cisco we use EIGRP as our routing protocal. But with this router all I see is:
#router ?
odr On Demand stub Routes
rip Routing Information Protocol (RIP)
Where is my EIGRP ? I can't configure eigrp, so my router wont be doing much routing.
I have a issue in my network, i have 2 data connections with 2 different ISP (Principal & Backup connection). But with ISP "X" the RTO are stable (RTO 240), but with the ISP "Y" the RTO is in 5000 and the connection always are flapping.
