Port Security and Mitel
Port-security is a layer 2 security feature so it will not be the cause of the call quality issues. Is it the same phone or group of phones each time? I've used Mitel with Cisco in two separate environments and have never had any issues. Can you include a topology of the network? -

CCIE Rack Rental VS Puchasing
I built my own lab. After tallying up the cost of the equipment, books, CBT's, and Narbik bookcamp I've got about 12k invested in my CCIE studies. Now, you can purchase a beefy computer, throw a bunch of NIC's in, and install GNS3 along with four switches and you could have functioning lab. My...- unclerico

Hands on with Cisco
Cisco Academy is your best bet to get hands on or buy your own lab year. Let me caution you though, if you don't have the requiste experience to possess a CCNP I would think twice about getting it. As someone who is often the interviewer I will look at your certifications and then look at your...- unclerico

Filtering out External Links in OSPF
the solution is incredibly easy if you stop and think about the different types of areas and how LSA's are propagated from one to another. a very easy win in this case is to split this up into two areas: - gi1/0/1 on R1, gi1/0/1 on R2, and gi1/0/1 on R3 in Area 0 - gi1/0/2 on R1, gi1/0/2 on R2... -
limiting access
are all of the devices on the same subnet or different? -
Configuring ASA IPSEC Tunnels
create two crypto ACLs and simply use multiple sequence numbers in your crypto map: access-list C-VPN extended permit ip 10.10.0.0 255.255.0.0 172.10.0.0 255.255.0.0 access-list D-VPN extended permit ip 10.10.0.0 255.255.0.0 172.20.0.0 255.255.0.0 crypto map mymap 10 match address C-VPN crypto...- unclerico

Configuring ASA IPSEC Tunnels
Yes, you can use the same address for all tunnels. The only thing that will change between the three tunnels is the tunnel-group since it needs to be specific to the remote IP address that you are establishing the tunnel with. Simply create your first one and then duplicate that as many times as...- unclerico

info not being relayed for AD evnironment with cisco dhcp
can you post your dhcp pool config? -
Routers and RIP
I'm assuming with the output you posted earlier that you probably have a hub and spoke topology with three routers and you're sourcing the traffic from the hub router. The reason I asked about CEF is that by default it will do per-destination (technically per flow) load-balancing. You're seeing... -
Routers and RIP
Are you using RIPv1 or did you not issue no auto? Do you have CEF enabled? If yes, is it configured for the default of per-destination or did you change it to per-packet load balancing? -
Two routers, two WAN links
Understand that it will take up to 40 seconds for OSPF to detect the failure. if the interface doesn't go down, then you have to wait for the dead-timer to kick in. You should use bidirectional forwarding detection (BFD) in addition to this perfect OSPF config provided by Andy, or tweak your... -
Frame Relay Question
Mostly true. I say mostly because the second you enter a frame-relay map statement on a multipoint subinterface or the physical interface itself, InARP is disabled. Also, on a point-to-point subinterface InARP is ignored.- unclerico

Two Cisco 2950's fighting on my network?
I would like to see a diagram of your network and where these 2950's are placed. Include any redundant links and identify your current STP root. Out of curiosity are you running a flat network using VLAN1 end to end? -
IPVPN cloud / vpls
ok, so since you are using L2 VPN I am making the assumption that you have a full-mesh of BGP peers between all of your locations. if so, you can take care of this on your CE in the location that is originating this prefix. L1 is the location where you are sourcing 10.10.10.0/24... -
Frame Relay Question
Since you posted in the Certification forum, I'll nudge you in the right direction, but I won't give you the answer. Hint: Look at the interaction between LMI Status messages and Inverse ARP.- unclerico

Two Cisco 2950's fighting on my network?
So just to make sure I am reading this correctly, you are saying that all of the clients connected to first 2950 become unreachable? -
IPVPN cloud / vpls
is this just a point-to-point connection or do you have multiple sites involved?? do you control the other sites CE device?? there are a few different ways to tackle this depending on your structure. -
