[c-nsp] vrf-lite and ipv6 / Cisco 6500/Sup720-3B SXI7

[Sebastian Faerber]

Hi,

i'm trying to implement vrf-lite and route-leaking to separate some
traffic on a 6500/Sup720-3B running 12.2(33)SXI7.
What i'm trying to achieve is that all traffic from the customer1 VRF
is forced to go out via my default-route, it's ok that
incoming traffic is routed directly to the customer1 VRF.
IPv4 seems to work great but i'm having some problems with IPv6.
Is there some way to dynamically import my v6 default-route from the
global table into the vrf (like import ipv4 unicast)?
I'm currently using a static route but would like to change that if possible.

I also noticed that I can't reach (ping) the v6 IP on the customer1
VRF Interface (Vlan123) of the router from servers directly connected
to this routers global routing instance (Vlan5). v4 is working fine,
forwarding v6 Traffic works too, it seems only
packets generated directly by the router don't work.
I also tried to setup a BGP v6 Peering in the VRF customer1, but the
session stays Active, i assume because of the same problem.
Again, a v4 BGP Peering works as expected (even tried announcing v6
Prefixes over the v4 Session but didn't work).
Any hints or is this unsupported and i'm abusing the feature?
