encapsulation if used for end to end communication and would fail if both sides of the connection are configured with different encapsulation types. Make sure the other end is configured with ppp encapsulation.

How can I make a router silent to the network that will only accept and receive ftp traffic? Will an extended ACL do (permitting only ftp traffic) or will I have to turn anything else off such as CDP and keepalives. I basically want it to be invisible... Thanks

Adding a hub does not create another collision domain because a hub does not filter traffic. It does eliminate the dedicated bandwidth that a switch provides because a hub divides the bandwidth with all attached users/devices.

You may want to use backup interface or watch lists, which are much better than floating static routes. They do not pass routing table information when primary goes down....

Be careful with multihoming, it will cause you to become a transit between the two ISPs. That means that you receive both of their routing tables (which is not a good idea trust me). Sounds like you have a routing issue....

typo i meant 2503 and 2505 can only have 1 dialup session at a time

The 2503 and 2509 are not made to be used as access servers because you can only have 1 dialup session at a time (1 aux port). The 2509 has 8 asynchronous serial ports and the 2511 has 16 asynchronous serial ports....... Both have 1 Ethernet port and 2 synchronous serial ports. This way you can...

They save their config's automatically.... To reset the switch back to factory defaults, use the delete nvram command or use the menu option to reset it....

An access router is basically a router that is used to allow remote users access to the network typically through async connections.

The reason why you can't trace route from inside with the static IP's is because they are private addresses. Qwest is probably blocking traceroute to prevent anyone from tracing back to you to try and prevent spoofing. Remember, private addresses can be anyone and therefore cannot be traced. The...

When you set up dynamic routing protocols, example router RIP, OSPF, IGRP, etc, you only list the directly connected networks, but do not include the subnet masks.

After you change the configuration register, and do a show version it should say 0x2102 next reload. type reload and then do a show version it should have changed

Did you test the cables with a "cable tester". If not, use a multimeter and ohm the matching (corresponding) pairs at each end for continuity. The jack wiring scheme is listed as 568A and 568B configurations. Double check and also check your punch down connections in your...

Check to make sure the subnet masks match on each router. I would then check to see if the DTE & DCE (on the cable ends) match the configuration. DCE should have the clock rate set on it. Then try something simple as a no shutdown on the interfaces. If you already double checked everything, try...

The WICs used on the 2600 routers have a smaller connection than the 2500 routers. I can't seem to remenber the number of pins that it has. When you order the routers, they come with the DTE DTE cables.

CDPm is a Cisco proprietary protocol (Cisco Discovery Protocol) and can only be used with cisco devices. I'm not sure if there is anything that can tell you all devices on a network.

You can NAT different pools on seperate interfaces. You still only have a certain number of global addresses in which can be accessed. You can configure inside NAT to allow inside local host to access to global addresses from the NAT pool. Hope I helped

IPv6 is defined by RFC2373 (revised #), not sure about the three-way handshake with IPv6

When you assign an access list to an interface, it's: ip access-group 101 (in/out) you have to specify the direction

create an access list preventing UDP on ports 137 and 139 on the router (inbound).
