When you show the interface of a port for example and you see the following: 150119586 packets input, 332937997 bytes, 0 no buffer Received 117056 broadcasts (0 multicast) 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog...

I mean, the second router receives the advertised route but it doesn't add it to it's routing table.

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...

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...

I have a question regarding Private AS Numbers, basically anyone can use them for their own internal organization? are they basically the same in terms of private ip addresses? And what are the consequences of not removing the private as's ( remove-private-as ), only thing I can think of is...

I have three routers set up using BGP, and am curious about the command show ip bgp. ISP1-------BIGISP-------ISP2 ISP1#show ip bgp BGP table version is 11, local router ID is 210.210.210.1 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e -...

So it also includes esp and sh for example?

When creating an access-list for example access-list outside1 permit ip host 1.1.1.1 host 2.2.2.2 What does the parameter ip include? Is it TCP,UDP, and ICMP? or anything that uses an IP address? Thanks.

Yes, I'm familiar with using statics. But would like to understand Reverse NATs and NoNATs. Do you by chance happen to have a working example?

Just a lab scenario, want to get a better understanding of Reverse NATs and No NATs.

Hello, I'm having a problem getting reverse NAT's to work properly. I'm not entirely sure what I'm doing wrong so any help would be appreciated. A piece of the config interface ethernet0 10full interface ethernet1 100full nameif ethernet0 outside security0 nameif ethernet1 inside security100...

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...

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.

Yes, I forgot about hardcoding the speed and duplex . Had to set it to 10/Full on both interfaces for it to connect.

I have two 501 pixes that I'm using to learn. I'm trying to connect them back to back to setup a VPN and can't seem to get it to connect. I've tried using a cross-over cable, it lights up but I can't ping each other. I tried using a straight-through cable, though it doesn't light up. Next...

I know that on the cisco routers you can know what files are stored in flash, but when I try doing so on the PIX I get something for example that looks like this pixfirewall# show flashfs flash file system: version:3 magic:0x12345679 file 0: origin: 0 length:1941560 file 1: origin...

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...

Is it possible to have an area connected to another area that is not the backbone? Can you link multiple non-area's together? For example the following. R1-----R2------R3-----R4 A0 A1 A2 A3 Thanks.

I'm trying to further my understanding of BGP and have reached a snag, I'm not sure if it's my configuration or if it's my understanding of it. I have three AS's; AS1, AS2, and AS3. AS1 is connected to AS2 which is connected to AS3. There are two computers, Computer1 is attached to E0 of...
