Hi,
has anybody successfully managed to get a working IPv6 session between a Cisco and a Juniper router using Link Local IPs?
I got it working between two cisco routers and two Juniper Routers but not with the two different vendors.
Configuration on the Juniper site:
...
family inet6 {
address FE80::1/64;
}
...
protocols {
bgp {
...
group customer_ipv6 {
neighbor fe80::2 {
local-interface at-2/0/0.119;
peer-as 65300;
as-override;
}
}
}
}
Configuration on the Cisco site:
interface ATM0/0/0.1 point-to-point
bandwidth 2033
ip address 10.194.235.42 255.255.255.252

The Cisco Router is running IOS 15.2, the Juniper Site JunOS 10.4
Any Ideas how I can get this to work?
Thanks in advance!

Stefan,
At a glance (and the RP guys can make better comments here) it looks like the problem might be somethign like IPv6 address family not enabled on Juniper (not that I'm not aware of defaults).
I dug up some link:
http://www.occaid.org/tutorial-ipv6bgp.html#juniper
they enable:
family inet6 {
any;
it is most likely the equivalent of our address-family ipv6
neighbor FE80::1%ATM0/0/0.1 activate
Just a thought ;-)

Thanks! The family inet6 indeed got lost during the debugging (I also think that this may be optional because I got a working session between both routers using global unicast IPs)
Another problem was a wrong AS number in the neighbor statement on the Cisco-Router (remote AS is 20570).
But it still isn't working. The debugging output now:

0) Do you see similar scenario for working session? (Between two Cisco routers)
1) What verion of IOS are you running? Something failrly recent I hope?
2) Can we have some more info from Juniper side (logs/debugs).
3)

Marcin,
I updated the debugging log, the previous one was created using override-capability-neg on the neighbor (experimental).
>>0) Do you see similar scenario for working session? (Between two Cisco routers)
The working connection between two cisco routers doesn't show any output
>>1) What verion of IOS are you running? Something failrly recent I hope?

Stefan,
From where I'm sitting I would so this.
1) Start stripping down and being verify specific when enabling features (say enabled IPv6 but only unicast and not multicast).
I.e. use only basic features and enable them one by one.
2) You can try config similar to this:
router bgp 65000
no synchronization
bgp log-neighbor-changes
neighbor FE80::1 remote-as 65002
neighbor FE80::1 dont-capability-negotiate ! this is hidden command
neighbor FE80::1 version 4
no auto-summary
!
address-family ipv6
neighbor FE80::1 activate
exit-address-family
That's not healthy in the long run ;-)

Hi Marcin,
in the end the solution was way more simple and obvious than I thought.
I tried using different connections (ATM/Ethernet), different routers(M40/M320), different IOS and JunOS...
First I got it working with Ethernet and JunOS11.2, then I downgraded JunOS step by step and it was still working.
But not on the ATM link. So this "must" be an ATM interface issue on JunOS? Unlikely...
The solution came to my mind, when I tried to set the Cisco site passive... nothing happened any longer on both sites.
Why is the Juniper router not trying to reach it's neighbor? Let's get back to basic pings....
Lucky I copied the interface string from the routing-instance:
> ping fe80::2 interface at-2/0/0.119
ping: at-2/0/0.119: invalid interface name
D'Oh!! Couldn't be!!!
But it was really only a typo in the interface name
Correcting the interface string to at-2/2/0.119 and commiting:

But many thanks for your assistance!
