What I'm doing wrong with IPV6 RIPng

I attached a image of my topology. I have problem with router 8 with not learning IPV6 rip route. Both Router 6 and 7 are learning, but not 8.

Router 8 config:

The following is the debug for rip and it looks like it is both sending and receiving RIP

Nice use of config posting, but RIP configs need network commands

Incorrect, you need network commands for IPv4 RIP, notice this is IPv6

To the OP, can you try it without the default information originate command? I doubt thats the issue, but may as well rule it out. What does show ipv6 protocols show you?

APA

what do you see in the RIP database?

deth1k

Can we have:

sh ipv6 route
sh ipv6 rip data

Cheers

R6's Fa0/0 is config'd for the following:
ipv6 rip RIP_Zone enable

All other interfaces on R6-8 are config'd for the following:
ipv6 rip RIP_ZONE enable

The RIPng routing process name is case-sensitive.

......goddamn you and your good eyes

Truthfully, spotting crap like that will go a long way in the TSHOOT exam. But the struggle to fix the broken is the best way to learn IMO. $10 says you won't forget the case-sensitive tidbit again!

I recall a tshoot lab (in practice, not the test... i have not taken the test) where a key-string had a password of c1sco on one end and clsco on the other. I dont know if you have ever had a "1" and a lowercase "L" in terminal but they look almost identical.

Point is, be prepared for stupid crap like that.

Oops, I spoke too soon

According to Cisco:

"The big difference between RIP-2 and RIPng configuration is that RIPng discards the ageold RIP network command in deference to the ipv6 rip name enable interface subcommand, which enables RIPng on the interface"

good catch Bert!

I need a mobile that has more screen real estate......

BINGOOOOOO!!!!, Now it is good. I know about the case sensitive and I was looking for that problem, but for some reason I look global RIP config and if you see on the global config on router 6, it only have the rip for RIP_ZONE, but I didn't look for the specific interface thats the reason why router was not learning rip router. Good eye

You are damm right, this is the best way to learn by struggling with little things like this. I can double that $20 that I won't forget this. Thanks guys

Heero

in this case, it really stands out when you see that R6 has two "ipv6 router rip <process name>" commands. They are like right next to each other as well.
