eigrp lab 1...


the switch is zeroized to vlan 1... i gave it a management ip of :

vlan1#sh ip int brie                                                           
Interface                  IP-Address      OK? Method Status                Prol
Vlan1                      10.1.100.99     YES manual up                    up 
FastEthernet0/1            unassigned      YES unset  up                    up 
FastEthernet0/2            unassigned      YES unset  up                    up 
FastEthernet0/3            unassigned      YES unset  up                    up 

and put r1, r2, r3 in ports f0/1 - 3...  go figure...

the excitement is driving me out of my tits...

here's the thing... you spend 50 bucks on the book plus shipping and you know damn well it's gonna start in beginners and it's going to be painful at first but the question you have to ask yourself is, "are you that good that you can afford to skip a single page, just in case?"

you bet your ass you're not...

suffer...

Jul 21 15:00:56.067: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 10.1.100.3 (Fas

the point...

r1#sh ip eigrp neigh                                                           
IP-EIGRP neighbors for process 1                                               
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq   
                                            (sec)         (ms)       Cnt Num   
1   10.1.100.3              Fa0/0             13 00:00:38    3   200  0  6     
0   10.1.100.2              Fa0/0             13 00:13:13    9   200  0  7     
r1#

the method to the madness... the H stands for handle and lists the order from 0
in which peering sessions have been established... this is an internal number used by eigrp to refer to a neighbor...

behold:

r3#sh ip eigrp neigh
IP-EIGRP neighbors for process 1
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
                                            (sec)         (ms)       Cnt Num
