I am reviewing the v2 release of ICND1 course materials. Looking at the student guide pg. 2-67 and 2-68, there is a screenshot of a routing table; some routes are marked with a C (directly connected) others with an L (local route). The explanation is...

What does this error message mean? How to fix the problem? The set up is this: router is configured as DHCP server with a single client manually bound. The client receives its IP address and default-router address, as configured, as expected. The cli...

The command “ip subnet-zero” allows the use of the all-ones and all-zeros subnets. How do routers distinguish 192.168.x.255 (/28 for example) directed BC to the last subnet from all subnets BC in the whole class C network? Or 172.16.255.255 directed ...

Can someone please explain to me an inconsistency in the ICND1 Lab Guide concerning the calculation of usable subnets? I emphasize “usable” since Cisco does. Lab 4-3, Task 4 states that we are assigned the address space 192.168.111.0 /28. Q2 asks how...

Thanks for the link. It appears there are several things going on with L routes. I summarize from the link you provided:"1. when you configure "redistribute connected" under any routing process, the connected routes are redistributed, but the local r...

Oops! Elementary mistake on my part. The masks have now been harmonized at /26: all is well. I find it surprising that the DHCP process completed despite the mis-matched masks and that the error appears as an ARP failure. "Error 22" is singularly unh...

Tyler,Thanks for your reply. I have found that as far as the exam is concerned, the crucial piece of information is whether the CLI command "ip subnet zero" is on or off. If the function is on, then usable subnets equals total subnets; if off, then u...
