I have a Procurve 5406 and I'm trying to propagate a multicast to all the vlans. I have pim-sparse running on all the subnets. I do get the multicast to forwared but occasionally it will get pruned to one of the vlans. I am trying to set it up so that this multicast will allways be forwarded...

Are you useing scrambling on this DS3 link? I had a simular issue on a DS3 link between two Adtran CSUs and the problem was long strings of 1's and 0's causing a loss of clocking. As soon as we turned on scrambling the link flapping problem cleared up. Good Luck, Googer

No that is on the passport 8300. Are you having 1200 problems. We had those previously and they were problematic. Nortel finally told us not use the layer 3 capabilities as the hardware had trouble keeping up. Googer

I have never tried this with PCAP but the same thing happens with port mirroring on the TX cards. You can mirror inbound or outbound but not both. I suspect this is the same issue. My understanding from our Nortel SE is that it is a hardware limitation on the TX cards. Good Luck, Googer

There is a problem with the 8600s if you are using SMLTs. In the case of SMLTs you need to use all E cards. I did not get an exact explanation from Nortel as to why this was but they said that the cards on both side of the SMLT should be E cards in order to operate properly. We made this...

Looks to be. We recently upgraded to the 2.1.2 version of code and so far everything looks good. Googer

I have had this problem for the fourth time today. Once again I just dropped a port out of the MLT and it started working. It is worth noting it was a different MLT port that I dropped than last time. Am I understanding you correctly that you want only one trunk port member per octopid? My...

I have heard of one issue where the VRRP can loose connection to its partner do to a problem with Windows XP. XP runs a service called SSDP that conflicts with the VRRP mechanism on the Nortel switches. SSDP dynamically tries to discover routers on the network and my understanding is that if...

Update. Adtran came out with a patch that fixes this problem. Googer

In site manager this is under "Protocols", "IP", "Static Routes". Googer

Octipid related how? I'm not familiar with that. Unfortunately, we do multicasting on our network so I can't turn off igmp without making things worse not better. Googer

I have now seen this for a third time. This time it was a server on one 8300 was not able to talk to random servers on the other 8300. Playing a hunch I downed one of the MLT ports that uplinked the 8300 to the core and everything started working immediately. This also worked the second time...

I did get an update from Adtran on this. They have run into this problem before with Nortel Shasta products and it has to do with the way PPP is handled. They fixed the problem on the Shasta and are now working on fixing it for the ASN/BayRS routers. Googer

No nothing specific from Adtran. I did try adjusting the MTU size already though and that did not fix the problem. Thanks, Googer

I finally tracked this down useing some PCAP/TAP data. It turns out the Adtran router does not use a standard OSPF packet when sending OSPF over PPP. Adtran has acknowledged this is their problem and their developers are working on a patch for this problem. The non-standard packet was the...
