tshoot ipv6...

so i'm a trunk and etherchannel guy... i use routed ports on switches infrequently... for the tshoot topology it is necessary to make routed ports on the dsw's as they connect from gns3 (nix/3750) to their interfaces...

dsw2#sh ru int f0/14                                                           
Building configuration...                                                      
Current configuration : 87 bytes                                               
interface FastEthernet0/14                                                     
 no switchport                                                                 
 ip address                                          

on dsw1 it's f0/1... why not f0/1 on both sides... not sure about you but i like a little uniformity anywhere i can get it... in fact when i was recabling, i looked at that cable in f0/14 and yanked it out, started to build it on f0/1 thinking it was my dumbassness and then i looked at the diagram and laughed... i still haven't figured that out... sometimes there's no accounting for shit...

so the side link between the dsw's, fa0/23-24, i trunked and made an lacp etherchannel... as i progress to the v6 part, that ain't cuttin it...

so i bundled the f0/23-24's on both sides with no switchport, and no ip address... then on the po3 interface i placed an ip address, thus...

dsw2#sh run int po3                                                            
Building configuration...                                                      
Current configuration : 84 bytes                                               
interface Port-channel3                                                        
 no switchport                                                                 
 ip address                                          

i missed that piece...

now i can put a v6 address on both sides...

dsw2#config t                                                                  
Enter configuration commands, one per line.  End with CNTL/Z.                  
dsw2(config)#int po3                                                           
dsw2(config-if)#ipv6 add 2026::3:2/122                                         
dsw2(config-if)#ipv6 enable                                                    
dsw2#ping 2026::3:1                                                            
Type escape sequence to abort.                                                 
Sending 5, 100-byte ICMP Echos to 2026::3:1, timeout is 2 seconds:             
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/6/16 ms
