question about loopback interfaces

Could someone explain the importance of using loopback interfaces? I keep reading that it is important when using routing protocols to use loopback interfaces. A consultant that is writing documentation for me suggested I obtain an entire class C network just for loopback addresses. Cisco says

another one passes the BSCN

Just passed the BSCN today - thanks to everyone who helped answer my routing questions! Although I did pass, I'm still going to go back and do some reviewing, particularly on redistribution. Three down, two to go... _ FAQ, list archives, and subscription info: h

BCRAN question

For those of you that have passed this test, how important is it to know the various models of routers? I'm familiar with the different series routers and what Cisco recommends them for (i.e., branch office, telecommuter, central office), but do you have to know it down to actual port configurati

bgp question and subnetting

Scenario: Let's say you have a class C subnet that you break off into two smaller networks: 1.1.1.0/24 = 1.1.1.0/25 + 1.1.1.128/25 Problem: You are announcing this through BGP, but your provider only allows you to advertise full class C addresses. The problem lies in that you have to announce t

Re: distribute list problem

Here's my $0.2... Few questions, just to cover the obvious: 1) Is your ISP doing filtering that might prevent this route? 2) Did you ever advertise this without the distribute lists? If so, you may need to clear the bgp route to your 202.161.128.173 neighbor. 3) Although you have no synchroniz

eigrp, frame relay, and ISDN

So here's the scenario...Numerous routers in a central site connected to other remote sites via frame-relay with backup ISDN. Question: What is the best way to implement EIGRP in this scenario? My thoughts were to run EIGRP over the frame, set up the dialer interface / bri as a passive interface

isl trunk on 6509

I  was trying to set up an ISL trunk on my gigabit fiber link, but it responded that it was only able to run in nonegotiate mode.  Since this is going between two 6509s gigabit fiber link, I was never able to exchange VTP information between the two in nonegotiate mode, and it wouldn't let m

I have this set up on a  Linux box without any problems.  I used the Cisco IOS 12.0 Security book as a reference.  (It also covers Radius)   - Original Message - From: Glenn Flood To: '[EMAIL PROTECTED]' Sent: Tuesday, October 24, 2000 10:17 AM Sub

BGP Challenge

ok, so I'm trying to implement some BGP routing for the first time.  I've read through the advanced IP network design, Internet Routing Architectures, the RFCs, and a couple other books on BGP.  But as we all know, none of this compares to good experience.  So, before I attempt to implement

Re: Repeated Questions

I just took my BCMSN test a few days ago (and passed-yippee!) and had the same thing happen. I had to read the question several times to make sure I wasn't reading it wrong, but yes, it was the same question. (Luckily, I knew the answer!) - Original Message - From: "Chan Yew Weng" <[EM

EIGRP and snapshot routing?

According to the Netcerts BCRAN book, snapshot routing works best with RIP, IGRP, RIP, RTMP, and RTP. No mention of EIGRP is given. Does anyone know of any reason why EIGRP would NOT be a good candidate for snapshot routing? _ FAQ, list archives, and subscriptio

Quick Survey: Con or Aux?

Today I got into a discussion about the appropriate place to connect a router for remote management of routers. If you plug it into a console port, you have the ability to reset the router and recover the password. However, if you get disconnected, you leave a session open, causing a security pro

OT: ciscoworks2000

Any one know of any good documentation on CiscoWorks2000 on Solaris? The manuals that come with it are basically just install guides, and Cisco's web site doesn't seem to have a whole lot. Looking for something that gets a little more in depth than just how to install it. __
