Network 0.0.0.0 needed?

When redistributing a default route learned via EIGRP into BGP it
seems the route will not propagate into the BGP table unless you have
network 0.0.0.0 configured under BGP.  Does anyone know why this is
necessary?  A safety measure perhaps?

Thanks!

You can also do this with a "neighbor x.x.x.x default-originate" command 
under "router bgp"

BGP was designed for the Internet, where there is no default-route.

Hi, shouldn't > (= 0/0 0/0) => NIL or > (= 0/0 0/0) => T instead of giving out division by zero? 0/0 is different from 1/0, which is the non-existent number n such that 1 x n = 0. The actual result of that expression depends of what you think 0/0 is. I personally feel that 0/0 is any number n such that 0 x n = 0, that is all numbers. hal9@cyberspace.org (Hal Niner) writes: > Hi, > > shouldn't > > > (= 0/0 0/0) => NIL > > or > > > (= 0/0 0/0) => T > > instead of giving out division by zero? 0/0 is different fro...

dhclient leasing 0.0.0.0

route 0.0.0.0 twice
Hi, I some doubts question regarding a Cisco config. In the config I can see the following two lines: ip route 0.0.0.0 0.0.0.0 192.168.1.1 ip route 0.0.0.0 0.0.0.0 192.168.1.2 I know that these addresses are active in two interfaces.

Behavior of 0 and 0.0...
I was playing around with the basic math functions, and I had some questions about the way Ruby handles operations with 0 and 0.0. first we have: $ ruby -v ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux] $ irb irb(main):001:0> 0/0 ZeroDivisionError: divided by 0 from (irb):1:in `/' from (irb):1 This is OK, it lets us know that we made a mistake somewhere, but when we try 0.0/0.0 we get: irb(main):002:0> 0.0/0.0 => NaN Mathematically, this is preferable to division error, but, maybe not from a programming standpoint?

0**0
Hello, I didn't find in the standard, what should be the interpretation of 0**0, 0d0**0, etc. ? I ask because I just noticed with Absoft compiler (ver. 11.5.2), that 0d0**0 == 1d0, whereas 0q0**0 == 0q0 (q for quad precision numbers). Thus, porting some double precision code to quad precision gave me unexpected results.

My guess is that you shouldn't be relying on this at all. Both answers are probably "correct" in the sense that the compiler can do anything if the code is invalid, and these operations are probably not allowed, so the question of the "correct" value is moot.

Hi, There is no reason why a process should ever send packet with src IP set to 0.0.0.0 The only thing I can think of, is a broken application. Or some sort of security tools using a spoofed IP.

Laptop configuration: 1. obtain an IP address automatically 2. obtain DNS Server address automatically I ran "ipconfig", other computers says IP:192.168.1.1** and mask: 255.255.255.0.
