Hello,
I was approached to add IGMP snooping to some devices for traffic that is doubletagged through the network. I don't know what VLANs are being put into the doubletagged vlan. Customer having troubles with flooding of multicast to 4 locations.

Hello,
I have an issue getting multicast to work for a new device. Trying to replace the old device, but it seems that when the new device is using multicast the route is pruned. Not sure how to fix this. Using PIM sparse-mode.

Hello,
I am trying to get ready to replace a 5K switch in our network with multiple 2Ks attached and a VPC connection to another 5K for redundancy. I expect the redundant switch to keep the traffic up and running while I replace the defective 5K, bu...
Hello,
I have a firewall with multiple contexts. We're trying to conserve a few contexts, but wanted to get multiple VLANs into the same context. Haven't tried it before.

Quick question. I'm updating some 5540's from 8.4(7) to 9.1(x) and looking at the upgrade path, their are updates that need to be completed for other versions that are later than 8.4(7), but 8.4(7) just looks like you can go straight to 9.1(x), which...

I hand them a port where I only hand off one VLAN, which doubletags on...
Chris R. filled me in on this after I left. I banged my head on my desk for months on this. I asked them to check the server and apps several times. "Not our problem, everything works fine."
Ah, I asked the tech to apply it to the BVI interface of the client (receiver). It was the BVI that had the main IP we use to route to it. Should it have been applied to just the LAN then? The issue is the network is part on an ISP and the other part...
Alright, got the ip igmp join-group command on the interfaces, but seems to have made no difference in the mroute table.YYM-6#sho ip mrouteIP Multicast Routing TableFlags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected, L ...
So I have some more information, but wasn't able to perform the join group command. So Client side router seeing this in the mroute, but nothing mapping the 172.27.1.81 to the route.
