Multicast routing issues when a subinterface is configured

Strange issue here. Cisco and the vendor are unable to help so far...
Most of our layer 3 lives on core switches. However, we have a couple sites off our WAN connected via Cisco routers. In these offices, we can not get paging to work.
I setup a lab and have finally determined what is at least causing the issue. My lab "branch" has the same problems, but I can resolve the problem by removing the sub-interface off the router.
On my LAN side of the router, with this config, everything works fine.
#--- THIS WORKS ---#
R1#
ip pim rp-address 192.168.251.254
gig 0/0 (connects to SW1 g0/1)
ip address 10.254.253.254 255.255.255.0
ip pim sparse-dense mode
SW1#
gig 0/1 (connects to R1 g0/0)
!no config - default VLAN1
When I apply this config...everything breaks. The phone goes off
#--- THIS DOES NOT WORK ---#
R1#
ip pim rp-address 192.168.251.254
gig 0/0 (connects to SW1 g0/1)
no ip
gig 0/0.777 (connects to SW1 g0/1)
ip address 10.254.253.254 255.255.255.0
ip pim sparse-dense mode
SW1#
gig 0/1 (connects to R1 g0/0)
sw mode trunk
sw trunk encap dot1q
int vlan 777
ip address 10.254.253.1 255.255.255.0
ip pim sparse-dense mode
int vlan 778
ip address 10.254.251.1 255.255.255.0
ip pim sparse-dense mode
gig 0/17 (phone port)
switch access vlan 778 (keeping it simple for now)
I have tried this on 2 different model routers, each with different IOS versions. The same issues follow each router. What is it about the sub interfaces?
Any insight? Calling all multicast experts! Thanks!

Hi,
creating sub-interface should not create any difference here. Only difference i can see earlier switch was working in l2 mode now it is participating in multicast routing as SVI is configured and pim neighborship established. Have you configured RP address on SW1. Please share below outputs from both devices
- running config
- show ip mroute <group>
- show ip pim rp address mapping

Routing issue with dual Ethernet NICs - Internal/External Configuration under Windows 8.1 - what am I doing wrong ?

I have a PC hosting Windows 8.1, attached to two Networks. One leads to the internet - and uses the private IP address (172.*) the other is purely internal (also using the private address 198.*) but, has no internet connectivity. I'm finding
that if I don't disable my internal NIC, I can't access any internet sites. Is this a bug, or have I not done something correctly.
I have also, a Windows 7 PC, attached to the same Networks, and it exhibits no issues when connecting to either the internet or to internal locations.
(Both are Enterprise builds, though only across a Windows for Workgroups network).
Can anyone tell me what I need to be doing with Windows 8.1 please, to make both internal & external network connectivity work as is the case with Windows 7 ?
I'm only running IPv4, and both Wired Networks have at their respective ends, Routers that support DHCP & NAT. Though the internal Router's external port is not connected to anything.
Thanks in advance...

Hi,
Can you tell me what you have tried so far and how did you set?
Firstly please update all network adapter driver.
After that, do the following:
1. Open the Command Prompt (Admin).
2. Run "Ipconfig /all" to check your nics IP information.
3. Use route command tell the computer which interface you want the packets to leave from.
Assuming Network A is...
10.10.11.0 /24
Router is 10.10.10.1
and Network B is...
10.10.12.0 /24
Router is 10.10.10.2
then use this command:
route add 10.10.11.0 mask 255.255.255.0 10.10.10.1 -p
route add 10.10.12.0 mask 255.255.255.0 10.10.10.2 -p
Hope this helps.

Help required in configuring multicast routing

Hi,
We have two 2 servers and 200 clients.
2 servers are in one vlan, 200 clients are in another vlan.
first server will send data to second server with multicast address 234.5.6.7
second server will send data to 200 clients with multicast address 234.5.6.8
first server is able to send data to second server.
but second server is not able to send data to clients.
If we put clients in same vlan, second server is able to send data to clients.
So we understood that multicast routing needs to be enabled in L3 switch.
Switch Model: 3550
IOS version: 12.1(19)EA1a
Any help in configuration required for this.........
Regards
SKRAO

Hi Skrao,
Does your client vlan and server vlan exist on same layer 3 switch if yes then perform this config and it should work..
On global config mode
ip multicast-routing distributed
On interface vlan config (for both client vlan and server vlan)
ip pim sparse-dense-mode
You can very well fine tune later.Try this and update if it worked.

Sys.UTL_DBWS issue when calling web service .......

Hi,
Background Details :
Linux : 2.6.18-164.10.1.0.1.el5 #1 SMP Fri Jan 8 02:34:10 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
Web Server : Apache Tomcat 6.0.20
Database : Oracle 10.2.0.4
Utility that we use to consume the Web Service from PL/SQL : JPublisher 10g Release 2 (10.2)
Load Balancer : Citrix Netscaler
We are using the Oracle built in package called UTL_DBWS to invoke the Java web service. The web service is been called through a Load Balancer called Citrix Netscaler.
Load balancer has been configured to use the Source IP mechanism to route the request to the appropriate web service.
Problem :
When invoking the web service from Pl/SQL (with the below piece of code) there are multiple times the web servers are been called which is supposed to be only once. The number of times the call varies is about to 2 or 3.
Query :
Hence we need to understand in general how the UTL_DBWS works ? Are there any issues when the call being made through the LoadBalancer ?
The default time out value while connecting ? If we want to override the default timeout how we can do that ?
Code for reference :
BEGIN
l_service := sys.UTL_DBWS.create_service (
wsdl_document_location => sys.URIFACTORY.getURI(l_wsdl_url),

Strange iChat AV router issue

Hello all,
I'm hoping someone can shed light on the situation I'm having with iChat AV attempting to vidoeconference with Apple's test servers (appleu3test01, etc...) When attempting to videoconference to the test servers on a macbook pro (10.4.6) powerbook g4 1.5 (10.4.6) mac mini core solo (10.4.6) it does not function behind our router (Cisco 1841 IOS version 12.4 3v ). However it works fine when I attempt it using the same iSight camera and the same port on our swith that I test the powerbook and mac mini with on my old 600mhz G3 ibook (10.4.6). This is baffling me to no end and apple support has not been much help over the phone. For reference this problem existed before we enabled our firewall on the 1841 and continues to exist after we opened up all the requisite ports. The OS X firewalls on all the machines are disabled. A few other people on this board seem to have problems with other cisco equipment, does anyone have a solution? Thanks,
-Brian
Cliffs: same network, all variables constant except machine
Works: iBook g3 600mhz
Doesn't work: Powerbook G4, MacBook Pro, Mac Mini Core Solo
Edit: forgot the mention the error it gives is "Disconnected from video chat because: can't get video from the camera"

Here's the issue. VOIP as provided in our solution isn't handled through a separate box like vonage that i could just plug into the router rather than between the router an the modem. We have a T1 handled by the modem in a slot in the chassis of our Cisco 1841 router/firewall. The VOIP service is just a separate VLAN on the router. Also there were no configuration differences between the old ibook and any of the other machine's I've tried. It too was running 10.4.6, all current patches, etc... Our IP phones are Cisco 7960s which are on that separate VLAN.

Possible internet routing issues driving me crazy!

I've somehow hit a problem accessing a particular favourite website and it seems I may have a routing issue.
I've spoken with a friend who is fairly network savvy and he's suggested I raise a case \ complaint with BT. I thought I'd use this forum to test if I'm missing something I could be doing to fix it before logging a problem with BT Helpdesk!
I've a BT Homehub 2 (Current firmware   4.7.5.1.83.3.5 (Type B) and I can access pretty much all websites I care to look at without any issue at all, however the site I read most days is now no longer viewable on any of my 2 PC's nor my iPhone. When I try to access it I get no error messages at all just a blank white page.
Doesn't matter if I try using IE or Firefox or Chrome browers it's the same result - I just see a blank white page.
The site in question www.celticquicknews.co.uk (or www.celticquicknews.com) and is definitely available, as I can access it when using a site such as http://www.free-internet-organization.tk/ on both my PC's and iphone so I know the web site is up and running and available for browsing but since Thursday lunchtime I've had no joy in being to access that particular site directly wihout resorting to using another middleman site to let me view it.
I have tweeted the guy who hosts the www.celticquicknews.co.uk site and he's said his site is fine but has numerous similar queries around BTINTERNET folks having the same issue as I'm reporting.
I run McAfee Internet Security and having disabled the various firewall \secure browsing functions no improvement still no joy.
I did successfully somehow connect directy to the illusive web site this morning (Sunday 1st May) on my iphone at around 10am, but by the time I boiled the kettle to have a coffeee and sit and read the site it became inaccessable again on my iphone and both my PC's! So what's going on?

I've reset my HH several times over the weekend and am baffled as to how I can somehow have 1 site excluded from my browsing options for no obvious reason other than a suspected internet routing issue.
My iPhone is on ORANGE and when disabling the wireless connection it too is unable to view the site in question so it's a real pain!
Not sure where to go to progress this so any help \ guidance is very much appreciated.......
Solved!
Go to Solution.

Appreciate the help....been out for most of the day and checked in to see if any additional posts.
I tried pinging the site and it does seem to resolve OK and also tried accessing site via IP but same issue - blank white page.

The tracert comments make sense so that's helped me understand, thanks for checking that out.
So what's the best option for me? Am I wasting BT and my own time logging a case?
I'd not usually bother pursuing this for the sake of a single web site but I'm bemused how this has happened since last week?
Thanks again for all help and guidance.

Will a 2 port LAG setup between 2 cisco 200-50s create routing issues?

I followed this guide. http://sbkb.cisco.com/CiscoSB/GetArticle.aspx?docid=caae365b755f46f5989177cb68216304_Link_Aggregation_on_Cisco_Series_Managed_Switches.xml&pid=2&converted=0 and linked ports 2 and 26 on both switches. Outside IT staff seems to think this will cause routing issues if multiple vlans are not involved.

Hello,
VLANs are not required for LAGs to function properly. Once you configure the LAG members you can configure the LAG as a trunk port with multiple VLANs, and access port with just one, or even a routed port with an IP address on it.
As long as both sides of the LAG are configured the same way there won't be an issue. Since these switches are Layer 2 only, they don't even do any kind of routing, so your outside IT may have meant a layer 2 loop, which will happen with multiple connections between the same switches. But when you configure them as a LAG is treats those links as the same connection, so there is no layer 2 loop either.
Hope that helps,

Routing Issue for Remote Access Clients over Site to Site VPN tunnels

I have a customer that told me that Cisco has an issue when a customer has a topology of let's say 3 sites that have site to site tunnels built and a Remote Access client connects to site A and needs resources at Site B but the PIX won't route to that site. Has this been fixed in the ASA?

Patrick, that was indeed true for a long time.
But now it is fixed in PIX and ASA version 7.x.
Please refer to this document for details:

Routing Issue with 2 Nics on Windows Server 2008 R2

Good Day
My issue is I needed to set up port forwarding for a web server to communicate with our hotels management server to check availability.
Initially the server has a single Nic configured in the 172.26.1.0 /24 network , Its default gateway the Switch vlan interface 172.26.1.1
We have many vlans for all the systems in the hotel and the server also needs to communicate with 3 other servers on different subnets which it does just fine.
I now added an additional adsl line with a managed router which has an interface of 192.168.10.1 /24 , My servers second NIC has the IP address 192.168.10.2 with its gateway being the 192.168.10.1
This 192.168.10.0 network is in a L2 Vlan and the rest of the network does not know it exists. It was working fine then just stopped asfter i added a static route to the server , which i did with RRas... I did this as the server could not communicate with
just one of the servers..
If i disable the 172.26.1.0 NIC the port forwarding works but then obviously the rest of the network goes down.. I know its a routing issue but am lost
please help

Routing Issue with 3550

I am having a routing issue with a 3550 switch. I have 5 vlans and I need one of the vlans to access a different router based on destination IP rather than our edge router. I have entered a static route on the 3550 that points to the secondary router whenever a certain network is tried to be accessed. My problem is I can't seem to get the traffic to flow correctly. When I trace route an address on the Internet the path shows as expected, the 3550 then my firewall then my edge router. When I trace an address that is on the other side of the secondary router I get the 3550 as the first hop, then nothing. I can ping the address so I know the path is up. What could be the issue? Thanks in advance.

Hello,
in addition to Mahmood´s post, what do you have defined as the next hop for the default route to the secondary router ? If you use an interface on the 3550 as the next hop, make sure that whatever is connected is in the same subnet, otherwise use the IP address of the next hop. So, let´s say your remote network is 192.168.1.0, and the secondary router is connected to FastEthernet0/1, your default route should look like this if the secondary router is in the same subnet (in this example, the IP address of the secondary router would be 172.16.1.2):
interface FastEthernet0/1
no switchport
ip address 172.16.1.1 255.255.255.252
ip route 192.168.1.0 0.0.0.255 FastEthernet0/0
Otherwise, try:
ip route 192.168.1.0 0.0.0.255 172.16.1.2
where 172.16.1.2 would be the address of the secondary router.
Does that make sense ?

I'm trying to connect my MacBook Pro running on OS 10.8.2 to a Linksys EA3500 router and when I go to click on the set up icon I get an "unsupported operating system". Any suggestions on what to do? The Linksys site is useless.

I'm trying to connect my MacBook Pro running on OS 10.8.2 to a Linksys EA3500 router and when I go to click on the set up icon I get an "unsupported operating system". Any suggestions on what to do? The Linksys site is useless. Do I need some kind of upgrade?

Don't use the CD software its not necessary.
Infact put it in the trash.
Your router will have an IP address in the range 192.168.1.1
Connect your router to your Mac via Ethernet cable (They usually supply one with the router and don't worry which end goes where the Mac LAN socket is bi-directional)
Also connect your router to your telephone line.
Now open your Web browser Safari . Type in the IP address above and a Javascript control panel will launch
Enter the default password and username (They are on a label on the router )
Your now have the ability to set up your router.
Your will need the password and user name supplied to you by your ISP at a minimum.
Enter these and most modern routers automatically configure the basic networking setting.
You now need to go to the security setting and set this as WPA2 Personal (NOT Enterprise) or WPA2 with AES and TKIP which ever it refers to and create a pass-phase. WRITE it down
You should be online.
Now remove the cable and connect to the Wifi and enter that passphase.

No airtunes with pppoE due to routing issues?

I just switched to an optical fiber to the home internet connection (which is getting pretty popular here in Japan). Needless to say, the network is very fast, however, I can no longer use airtunes via my airport express network. The airport express stations (both of them) no longer show up in iTunes. My guess is that this is due to a routing issue and the same problem must have been encountered by others before and hopefully solved. The new internet connection uses pppoE to make a connection to the internet service provider. This gives me an internet address of the form 125.197.xx.yy. I still have my airport express set to get an address via dhcp (which the new optical fiber hub provides) and is of the typical private network form 192.168.1.4. When I am connected by pppoE to the internet, my iTunes cannot see my airport express due to routing issues I assume. Is there an elegant solution to this -- can I use my airtunes and the internet at the same time? Would modifying the internet routing help here (I have used this before when I have had multiple interfaces going (e.g. one in a secure local lan and the other supporting an internet connection via ssh to the outside world). Any advise would be much appreciated. I haven't tried asking my airport express to log in via pppoE -- is this the only solution?

Well as I have for my last several posts -- I solved the problem myself. I am pretty sure that the root cause was a routing problem (pretty obvious in fact). By have the airport express base station connect via pppoE itself (I have a remote relay airport express as well) and switching to NAT and DHCP distribution of addresses via the airport express, I can both see my airtunes as well as my ethernet connection. It is a non-ideal solution as I have a fixed IP which would have been convenient to log in from outside to, but I guess I can live with that.

With the same configurations MDB are not not getting deployed in weblogic 10 with some exception, so we removed the provider URL from weblogic-ejb-jar.xml and changed the JMS configuration to use foreign JMS and XA enable connection factory is set to true. Now when ever the JMS message is triggered Entity bean is not getting refreshed with the updated values. i.e values are stale.
Can some one look into this and provide your inputs to resolve this issue.

I think the Entity bean refresh problem appears to be unrelated to MDBs. The MDB is only responsible for getting the message to your application (which in turn interacts with Entity beans). You might want to try posting your question to an EJB newsgroup.

Audio tracks playing different audio tracks - routing issue?

I'm having trouble with some routing issues I believe. Here's the deal:
Some audio tracks are playing different audio tracks, when that region is not even in it. For instance:
Track #2 is Soloed. Output is Output 1-2. I hear the audio file that is in Track #1, which is NOT Soloed and I shouldn't even hear. I don't hear anything from Track #2. The only way I can hear Track #2 is by playing it from the audio bin, which obviously isn't going to work out right.
If I drag the audio region of Track #2 to a brand new audio track, I still don't hear anything. Is it possible this audio file(s) got corrupted somehow?
Please help!

Check the parameters, in the left side of the arrange page window.
To me, it sounds as if you have a bunch of arrange tracks, which are all playing back through audio track #1.
