Attached is BGP confederation configuration and Topology. They are taken from "Routing TCP/IP Volume 2" book.AS 65000 is designed as a backbone AS connected to non-backbone AS 65535, 65534 and 65533. All are member AS's in AS 1200.I have couple of questions as i think some parts of Sunshine's and Talisman's configurations are incorrect.
1. The next-hop-self keyword is mentioned only for Panorama router, why the keyword wasn't mentioned for Nakiska and Talisman routers? .. As we know, the next hop is preserved throughout the confederation, therefore, next hop self should be configured in all member AS's inside the confederation. The same thing with Talisman, why the next hop keyword wasn't mentioned for Lakeridge and Sunshine?
2. Why the remote-as keyword wasn't mentioned for Panorama in Sunshine's configuration while the keyword was mentioned correctly for every neighbor routers in Talisman's configuration?
3. I don't understand the below statements that are stated in the book, as it conflicts with the rule "MEDs are preserved throughout the confederation"
"AS 65000 can safely send MEDs to AS 65535. A route that includes 65000 in its AS_PATH is not accepted by Sunshine or Talisman, so MEDs sent from those routers to AS 65535 are not seen by other member AS's".
we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?
View 3 Replies View RelatedI am implementing a guest wireless network to work alongside my internal network. The guest network will use the existing switching network and will be separated by VLANs. I have the ASA set so that traffic can get to it and out to the Internet. I can set up a workstation on the same VLAN as my guest network and can route inside my network (strictly doing this for testing purposes). Where I am having problems is with the Catalyst 4506 switches and the ip routing. I had two separate "ip route" statements defined on my switches.
ip route 10.200.2.0 255.255.255.0 10.200.2.254
ip route 0.0.0.0 0.0.0.0 10.100.100.254
I have discovered that the traffic is always following the default route despite the fact that my IP address on my test workstation falls in the 10.200.2.x network. I was looking at documentation and found that it is possible to set up policy-based routing on the core switches. Can you have two "ip route" statements defined like this to segreate traffic or do I have to use PBR for routing (or a combination) in this case? If I define PBR then how does that impact my existing routing? I need to make sure that I can still route the existing traffic while I'm configuring this change.

View 7 Replies View RelatedI have a setup where - I have a cisco stack (4X SGE2010 Switches) trunking over to a 3COM switch. Both switches believe to be the "ROOT" of the network. Note The 3COM is running RSTP as opposed to the Cisco Stack which is running normal STP. To my understanding of STP - Essentially STP is not functioning! Both switches believe to be the "ROOT" so they don't shut ports down. (We are currently having major issues with ports going up and down for seconds at a time on both switches)

View 8 Replies View RelatedWe currently support a third party VOIP software. Recently we have had issues with our T38 faxing to our SIP Trunk provider because our FW (sonicwall) doesn't support Nating the connection address within the SDP packet of the T.38 reinvite. This has caused us to look at alternate solutions. I have been in discussion with CISCO sales engineers and can't get a straight answer on which one of their products support this(RFC 3362, T.38 protocol used by our VOIP server)We were looking at replacing our sonicwall with an ASA but it seems it doesn't support RFC 3362 either . However, the sales engineer thinks that their regular routers will. So If I purchase a cisco router, i.e 8xx or 2621XM the question is where do I put it in my current topograpy. Currently we our at a Datacenter and our drop into our cabinet comes right into the Sonicwall and we have all NAT handled there, routing to different LAN ports on the Sonicwall. On LAN side all we have are standard switches supporting all of our Servers.
If I buy a Cisco router to handle my NAT issue for faxing.Do I put it on the WAN or LAN side of my FW?Do I setup the router to handle all of my NATing or just the NATing of my VOIP server that is having issues with the T.38? Would I need a Sonicwall FW if I purchased a CISCO 891?

Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname). Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed. Its a system that has worked for us 3 or 4 times in the past. But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the 10.1.185.128/27 route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.

View 4 Replies View RelatedI have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).
I have to use 9 Cisco 300 series switches to build a new network. I will use one of them (core switch) in L3 for routing between Vlans (3 Vlans) and the others in L2. Is there a software to centralized all switches configuration, operation and monitoring?

With my brand new Cisco 3850 Switch, I got it configured with a LAN IP. Then, on my PC I opened up Cisco Network Assistant (version 5.8.5.1 which supports the 3850). I went to add the 3850 to the community by discovering the device, and was prompted with the user/pass box. The password I set was not allowing me to connect, and I realized it's because a username was required and I had not set up a username on the switch. So, I then configured an admin user with level 15 privileges on the switch. However, now when in CNA I try to add the 3850 to the community, it doesn't even prompt me for user/pass, it just says "unable to connect".
What do I need to do to add this 3850 to my community?
I have problems in my Cisco network until I connected some Moxa devices.This Moxa are models EDS-316 and EDS-208
My principal trouble is the traffic UDP. Suddently the network don't permit the traffic UDP in VLAN where are connected Moxa devices.
During an hour the Moxa can send TCP traffic, but can't send UDP. If a Moxa device is unplugged from network, all devices connected to him can work offile from principal network, but if I plugg again the Moxa is like disable.
After one hour (more or less) the system restart all functions and work fine.I catch the logs from TXerrorsInPorts and all the ports where is connected a Moxa have errors all time.
I don't know which is the problem, but I think that problem is in negotiation from Moxa to Cisco.This is the configuration from a port where is connected a Moxa: [code]
I have a Cisco 2948G switch that I am trying to communicate to through this program. It has both an IP address and is hooked up through a cable. I can get Cisco Network Assistant to come up and ask for it's Username and Password, and that it is where I am stuck! I have no clue as to what to put in there as a username and password? I do have a password setup on the switch to login in to it during terminal mode, but that is it.
View 1 Replies View RelatedLooking for input/thoughts on the upgrade of our 3560's and 3750's while on production network.
While we could remotely send the IOS over the network to the device, I'm concerned about errors and the lack of physical control of the device. So, the thought is to just go to the comm closet, plug in with laptop to the console port, and upgrade the IOS over the console port. But this would require xmodem, correct? I know the fastest way would be to a. configure an empty fa0/0 port to no switchport, add an IP address, and use tftp. BUT, we would have to isolate the switch from the production network while connected to it with our laptop. Otherwise, our laptop would be seen on the network as an unknown device, and there would be repercussions...
So, we console into the device, and u/l the IOS that way. Is there a way to increase the baud rate on the switch to 115200, change putty to 115200, then do the x modem? I just say we should shut all the ports to isolate the switch from the network, then tftp the IOS to the switch. Unplug, reopen the ports, then reboot the switch.
I have three 4506 switches with vlan 4 set as the management vlan. Switch 1 is connected to switch 2 and switch 3.
I can access switch 1 and 2 using telnet from the management vlan and both switches reply to pings. But from switch 1 or 2 I cannot ping or telnet switch 3. If I plug into switch 3 and I can ping and telnet switch 3 but not switches 1 or 2.
It is as if the management vlan 4 is not being passed to/from switch 1 and 3. The configs for the uplinks from switch 1 to 2 and 3 are the same. And the configs for switches 2 and 3 look the same apart from the port settings.
I have over 40 vlans running all that work fine between all the switches.
We have a 2960 switch which is connected to the core via a VLAN trunk. We have disabled broadcast port suppression but, the 2960 is shutting is shutting 2 ports down on the network and this looks like excessive braodcast. How and why would the switch start dropping traffic when the default is don't do anything? It had to be rebooted to get the port active again
