MCNS

Group- I bought a copies of "Designing Network Security" and "Enhanced IP Services for Cisco Networks" in hope of passing the MCNS test without taking the course. Should this be enough? If so, which should I read first? Is one more of fundalementals? All input is appreciated. /Jared

RE: redundancy

For the redundancy part you can define two static routes. Just make the administrative distance on the "backup" higher than 1. Something like: ip route 0.0.0.0 0.0.0.0 s0 ip route 0.0.0.0 0.0.0.0 s1 10 Don't know about the monitoring software? HP Openview? CiscoWorks? /Jared -Original

RE: Layer 2 switching and Layer 3

Actually the idea of "Route Once Switch Many" refers to MultiLayer Switching (MLS). Layer 3 switching is really just routing... -Original Message- From: William Wong [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 03, 2000 1:39 AM To: [EMAIL PROTECTED] Subject: Re: Layer 2 switching

RE: STP question

Spanning Tree will run its algorithm every time a port is plugged in (unless Portfast is enabled...) and ensure a loop free topolgy. The first port up will not necessarily be the one that stays in forwarding, it depends on several variables... bridge ID, cost to root, port priority... all of

VLAN design

Group- When implementing new VLANs, I like to use some sort of logic when assigning the numbers. For example, if a customer was assigning one VLAN per wiring closet, and the customer has 4 floors, and one closet on each floor, I would use VLANs 11, 21, 31 and 41. The first digit in the

BCMSN: STP topology changes

Ole- When the root switch sends out the topology change BPDU, it does not specify that Switch E is no longer available. It simply flips the Topology Change bit in every Configuration BPDU saying that there has been a topology change SOMEWHERE. This lets the switches age out entries in Forward

Switch limit?

Group- Is there a limit to the number of switches that can be a part of a single VLAN? I guess what I mean, is the number of switches that have ports that belong to a VLAN. I did not see this in Cisco LAN Switching. Thanks. /Jared

RE: Is a switch secure? (managed/unmanaged)

Sounds like you could go with a layer 3 switch (or a simple layer 2 switch and an external router), give each office's group of ports a seperate VLAN, and use access lists to block traffic between offices, as well as allow access to the internet and to VLANs that need to be accessed by two

RE: Switches !!!

Think of the RSM as a router that just happens to be inside a big switch. It can run routing protocols (OSPF, EIGRP) just like an external router can, which means it can make routing decisions without the aid of an external router. This also means it can make the initial routing decision for MLS
