IPv6

I lied.  I am working on IPv6 now.  I’ll do IP Services later.  I am pretty happy with IPv6.  Unfortunately the NM-16-ESWs in my 3640s on Dynamips have a fart when you try and configure an L3 Etherchannel between them.  Now I dont know if this is a Dynamips specific drama, if its the IOS I’m using, or if its the NM-16ESW itself.

*Mar  1 01:22:08.799: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/15, changed state to up

SW-1(config-if-range)#channel-group 1 mode on

SW-1(config)#interface range f0/14 - 15

would not accept channel-group command with no switchport

SW-1(config-if-range)#switchport
SW-1(config-if-range)#channel-group

Creating a port-channel interface Port-channel1

OK, L2 channel seems ok

SW-1(config-if-range)#
*Mar  1 01:22:15.135: %EC-5-BUNDLE: Interface Fa0/14 joined port-channel Po1
*Mar  1 01:22:15.171: %EC-5-BUNDLE: Interface Fa0/15 joined port-channel Po1
SW-1(config-if-range)#no switchport

Lets try making the channel group then making it L3 after

SW-1(config-if-range)#
*Mar  1 01:22:18.091: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to up
*Mar  1 01:22:18.571: %EC-5-UNBUNDLE: Interface Fa0/14 left the port-channel Po1
*Mar  1 01:22:18.575: %ESWILP_FLTMG-7-INTERNAL_ERR: Internal error: *** failure to create entry in vtable/vlan 1006/unit 0 -Traceback= 0×603C5124 0×62445AD0 0×6242F2D4 0×62435C50 0×62446340 0×6047F6C4 0×62439F9C 0×6240F680 0×624176B0 0×604057D8 0×604218B0 0×604C229C 0×604C2280

ARRRGGGGHHHHHHHHH

SW-1(config-if-range)#

Up yours Cisco!!!

Played around with it for a bit… Traceback city no matter what I did.  Im not that fussed though, Im pretty happy with RIPng anyway.  I already know how to make L3 Etherchannels so its all good.  I might come back later and just do some inter-router RIPng stuff rather than trying to do it over L3 Etherchannels.  It’s no different really.

Narbik’s OSPFv3 labs are just router only… Let’s try those.

    Good stuff Matt. I just fnished Switching but let me go back and try this on my 3550s. I will respond back to you! I am starting frame-relay today. Doing my best to keep up with you :)

    Hey mate, Did you try task 10. when I got up to this task I got the following error? did you get this. I’m wondering if this is a bug with Dynamips or if there is a a limit on the number of RIPng processes you can run on a router.

    R1-2-ipv6(config-subif)#ipv6 rip R1-R2-R3 enable
    % Too many RIP processes

    Hi Jonny,

    I didn’t get that error. What IOS are you using? I have c3640-jk9o3s-mz.124-16a.bin on my dynamips box. I doubt it is dynamips because it looks more like a software error than a hardware or emulation error.

    Cheers
