CCT is geared more for the technician in the field who needs to get basic stuff done without having to understand all the underlying theory. It is good for those who just need to "get it working" without having to explain "how it works". CCT provides great foundation for those who want to...

p2p or b'cast as long as you are the same on both ends. The biggest issue with trying to mix p2p and b'cast is the DR requirement for b'cast. For the IGMP, you'll need to enable PIM on the appropriate interfaces. However, as Andy states without more information, can't be too helpful here.

Check for mtu mismatch. Debug ip ospf adj. Interface command is: ip ospf ignore-mtu or adjust mtu on both sides.

More information please. Post topology and sanitized config for devices. Can router even ping itself? Check speed/duplex mismatch?

My 2 cents. A complete IP address requires both the address and the mask. Neither piece by itself gives full information about the address. For example: Given the address 172.25.33.55, how is it subnetted? Ans. Not enough information given. Best guess is it is at classful mask /16. When I give...

You might look into ip sla as a keepalive, but that may be too broad for what you're doing. https://supportforums.cisco.com/thread/2127218

The mac-address table (or CAM table on high-end switches) doesn't have a configurable timer. My focus will be on the firewall. I'm not familiar with the Kapersky but a Cisco firewall will timeout connections eventually when they aren't being used. After all, that's what a firewall is supposed...

Here is more information about what you had to do hamidrezaa for future reference. https://supportforums.cisco.com/thread/2003063

I doubt the switch is the culprit. However, there are underlying databases that might be timing out such as the arp cache on the hosts or even the mac address-table on the switch. Both those databases will clear unused entries after 5 minutes of inactivity, but a 60 min timeout indicates...

Hard to tell what you're asking, but if this is for admin access to the switch there is a timeout on the vty lines. By default it is set to 10 minutes of inactivity but is configurable. If you haven't already, look at: show run | begin line If you see: line vty 0 15 exec-timeout 60 0 That...

As long as your CCNA hasn't expired, any 642 level exam or higher (CCIE) will renew your existing CCNA.

First, your 2509 doesn't support OSPF. Cisco uses boilerplates in their IOSes so often you will see a command available when the underlying code doesn't implement the command. Second, Yes you can use your 2610 as a frame switch and a router. That is commonly done for lab environments.
