Cisco WAN :: Make PIMv2 Hello From C1921 Backwards-compatible With Old C3620
Jun 18, 2012
I observed that when I was trying to troubleshoot a field issue using two routers I had in the lab, that one of them (an ancient C3620) did not like the PIMv2 Hello messages sent to it by the newer one (C1921).
The symptom observed with multicast routing is that when a source connected to the C1921 tries to register with an RP running on the C3620, the multicast route stays in the "registering" state forever. But going "the other way" - with the source connected to the C3620 and the RP running on the C1921 worked fine.
what I see in the C1921 when it tried to register a connection to the group 224.0.0.39 (for Auto-RP). Note: The two routers are connected via a GRE tunnel. [code] PIM debugging on the C3620 showed the following when the two exchanged. [code]
I believe that the issue is down to the firmware in the C3620 simply being too old and not understanding the PIM options defined in RFC3973 or the Cisco private PIM option 65004 being sent by the C1921 (though the PIM debug does not make it clear whether it is just the unknown options that are ignored or the whole Hello message)
Is there any global or interface-specific PIM option I can use in the C1921 to "dumb down" the Hello message so that the old C3620 accepts it?

I have a Linksys WRT320N Wireless Router and I am having an issue where it seems like gigabit (10/100/1000) ready computers are getting fast ethernet (10/100) speeds and fast ethernet computers/devices are receiving gigabit speeds. What I mean is the computers that are gigabit ready and are using cat6 cables are showing green icons on the Linksys WRT320N router and my network switch, which is only 10/100 ready and uses a cat5e cable to connect to the router, shows a blue icon indicating it is connected at gigabit speeds. Is the manual incorrect and green icons really mean gigabit speeds?

I have a brand new C1921 with EHWIC-4G-LTE-G using Vodafone to build an internet connection. First I did the setup like shown in the config guides and got the internet connection, but it was unstable.
Then I found some issues with the old LTE- card firmware in the support forum. Following that hint, I did an IOS upgrade to 15.2(4)M3 and the LTE- card update to Modem Firmware Version = SWI9200X_03.05.19.04. Post-checks after the update were all fine.
After that, I reconfigured the router again meeting the config guides. Establishing the internet connection, I get an IP address on the cellular profile, but it's not bound to the cellular interface.
sh cellular 0/0/0 profile Profile password Encryption level: 7
Profile 1 = ACTIVE*--------PDP Type = IPv4PDP address = 10.25.124.59Access Point Name (APN) =Authentication = None Username:Password: 05 Primary DNS address = 139.7.30.125 Secondary DNS address = 139.7.30.126
[code]......
Before the upgrade the IP- address was bound to the cellular0/0/0 interface and I was able to reach the internet.

Traffic Generator TG connected to R1 via switch SW . One end of the R1 is LAN1 interface and other end is WAN1. LAN1 is connected to switch SW. WAN1 is connected to R2 WAN0 interface..
TG ------------- SW ------------------------------(LAN1) Router R1 (WAN1)------------------------------(WAN0)Router R2
I have to pass traffic to R2 WAN0 interface.
Wen I pass traffic say 5000 from TG, I'm to recieve 5000 at R1 lan1 interface but I'm not to recieve at R2 WAN1 interface and hence not to R2 WAN0 interface.
Config at TG:'

I'm currently trying to set up a new infrasturcture with PEAP.
So, i've got redundant CA routers (c1921), an ACS server and 1262 AP's. Everything is working fine and as i want it to.Certificates are autoenrolled and so on, but if the CA root certificate expires, how to tell the AP to get the new root CA cert.
The root-certs are made by auto-rollover, and rolled on the CA router, but I got no change to get this root-cert on the AP.Is there a way to get them in an automated way, like rollover or enrollment?

I am running two ADSL lines into one C1921 router with 2 ADSLoPOTS cards installed.If I copy the firmware flash file on to the router (adsl_alc_20190.bin) and reboot, only one card shows the new firmware (slot 0).So sh dsl int atm 0/0/0 shows new firmware but sh dsl int atm 0/1/0 shows no change.How do I upgrade them both?

C1921, running version 15.1(4)M2, with licence for "IP base" feature set only.Trying to pass multicast via a PPTP VPN from a Windows XP machine to work around a non multicast-aware WAN link
1. With the IP Base feature set I am able to create a plain PPTP VPN without any encryption; the Windows XP machine can bring it up and unicast data passes through it OK in both directions.
2. But when trying to send multicast, only one-way traffic is observed:i. Windows XP host on far end of PPTP VPN and a local PC both running old Microsoft tool "MPING.EXE", sending and listening for traffic on the groiup 225.100.101.102i. The distant host receives and echoes back the packets received from the local machine + sending its own (confirmed with Wireshark running at the far end)ii. But the local machine directly connected to the C1921 router does not hear any packets from the far end; Wireshark shows only the ones it is sending.
3. Group status ("show ip igmp membership") as far as the C1921 is concerned shows both ends (192.168.50.10 (local end) and 192.168.50.201 (distant end via the PPTP VPN)) joined to the group [code]
4. But "show ip mroute" for that group shows an error; for the source on the far end of the PPTP VPN (having the IP address 192.168.50.201), the source interface is incorrectly shown as GigabitEthernet0/0 (should be Virtual-Access2.1 for that PPTP VPN) and the outgoing interface is shown as Virtual-Access2.1 [code]
5. I have tried adding static mroutes and messing about with parameters for the virtual-template interface for the PPTP VPN, but the problem remains. And if I put another local PC onto a different Ethernet port of the router, the multicast traffic does flow both ways - so the issue is solely with the PPTP VPN.After a week of head-scratching I am getting more and more convinced that it's a bug... but wonder if it is already-known, has a workaround, or a fix in newer firmware?

I Set both of them up with the same workgroup name, and now my XP machine can see and access my laptop, but my lap can't see my XP machine. If it makes any difference, I can remote into my XP from my laptop, but that's not what I need.

Currently, I have setup a demo lab with the UC320W + IP Phones and OnPlus Network Agent all connected to a SG300-28P. I have just obtained an SRP547W because I wanted to use the 3G/4G internet connection via the router as my demo lab is an isolated network.Now, I tried to a couple of 3G modem (UMG181) and 4G Telstra modem (MF821) on the SRP547W but none of these work. I had a look at the compatibility tableI guess those modem models are not listed there. However, when I went on say the Optus website to scout for a more compatible model, none of them hit it right on the mark. The matrix says it can support E180 (while Optus has the E188), E353 (while Optus has the E353). I have already wasted my money on getting the earlier stated 3G/4G Modems and I ain't going to take a chance again.

We have a client that moved to a new office and WAP4400N can no longer reach entire office so we need to put in repeater. However, we have already tried one that isn't compatible so which model of wireless repeater is compatible with WAP4400N. Note, we do not use Wireless N and will not be any time soon due to older devices.

My onboard network adaptor card died so I bought a Rock USB lan Card RJ-45. It worked for 30 mins then just stopped working. When I look at the device driver details, it recognises it, and also says the drivers are up to date. When i try to connect to the modem for internet connection it says ....There might be a problem with the driver for the Local Area Connection 4 adaptor. A network cable is not properly plugged in or may be broken....Ichanged the cable, still same message, I went to the internet on another computer to download drivers but it still says drivers are up to date. My system is a hp p6380a home pc. Running windows 7 64 bit. Im thinking that it might be a faulty usb card but when I spoke to a guy at a computer shop he said that they are not compatible with 64bit computers. Ok then why did it work for 30 - 1hour.

I am trying to install the WLAN driver for Dell Dimension 9200C desktop computer running Windows XP but I keep getting the error that no compatible hardware was found. I've gone to the appropriate Dell Drivers site for the computer's model and I'm 99% sure I downloaded the correct software for WLAN: Dell Wireless 1395 WLAN MiniCard. After going to Device Manager and looking under "Network Adapters", there is no Dell WLAN card at all (direct ethernet connection for internet works). Is it possible that the computer cannot find the WLAN network card, which prevents me from installing the driver software, even though it exists? If so, what can I do? If not, I guess I'll go buy a USB network adapter.
