If you are asking how to add redundancy for end-systems in the event of an access-layer switch, you would need to add a link between each end-system and each access-layer switch, as you've done with CCM, and the 2821's.
Thanks for the info. Actually, the attached scenario is not yet implemented. In my Lab environment I am using one 2950 Switch all the devices i.e 2 CCM (Pub/Sub), 2 Cisco Router 2821 (Gateway) are all connected in the same switch.
What I want to do exactly is, If I will deploy those devices in real scenario as attached.
In CCM (Publisher) if I will connect the first interface to the first 2950 switch (access switch) and the second interface to the second 2950 switch.
In CCM (Subscriber) I will do the same thing with the publisher.
I dont know and I did not try yet If I will activate or enable the other network card in my CCM and attach to the other 2950 switch.
By default, in CCM server with two (2) network card like the one what I have, If I used the first port the other port is automatically disable by CCCM setup.
How can I setup the CCM servers (PUB/SUB) and activate the 2 network card and connected to the 2 access switches as a full redundant.
In 2950 switch, etherchannel would be a good idea and best solution.
In Cisco router 2821 (gateway) maybe you can advise me the best and possible solution.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
