    BGP and No Synchronization

    I've created simple lab environment and lets say you have two routers in the same AS, so it's using iBGP. The first router (routerA) has a loopback interface assigned such as 10.1.1.0/24 to mimick an internal network. When you use the network command to have the network advertised the second...

    Using Native VLAN on Trunk Ports?

    My understanding of using native vlans on trunk ports is so that the frames are not tagged, they're transmitted untagged and received untagged. But where is the application use of this, why would you want it untagged? Currently, I have vlans being sent across a trunk without a native vlan...

    Using network and broadcast address

    I heard that there was a way so that you can allocate your network and broadcast addresses to devices. So lets say you have the following IP space 222.222.222.4/30. Originally ---------- 222.222.222.4 - Network Address 222.222.222.5 222.222.222.6 222.222.222.7 - Broadcast Address But I heard...

    uptime/top - load average

    When you use the uptime or top command for example, you're given a load average. What exactly is a low, normal and high average? What should I be looking for exactly? I don't believe it's in percentage either.

    I've been trying to use traceroute on my router to see which path packets take, but would like to know if the AS numbers could be shown as well. I've checked out a Looking Glass and am wondering how can I do the same thing on my router? Is it only on specific IOS versions? Something like...

    I'm going to start learning about PIXs and am wondering what models should I aim for? I would like to learn about everything including things such as statics, ACLs, VPN access, .etc. I'm thinking about two 515s? Any suggestions? Or is that too much or too little? Just like CCNA and CCNP...
