[Xorp-users] Linux IPv6 MR

[Otto Solares]

Hi!

*(sorry for my english, not a native speaker)

I have a GNU/Linux router with 8 NICs doing routing
for 8 segments of the whole network in my University,
1 of those segments is commercial Internet and 1 other
segment is Internet2.

All segments are directly connected to this Linux
router and is working very well with latest kernel
(2.6.16.18).  I'm using BGP IPv4/IPv6 for importing
all Internet2 routes and for exporting my routes and
it also works fine.

Now I need to do multicast routing so I enabled all
respecting modules for IPv4/IPv6 in XORP but just
IPv4 multicast routing works, IPv6 multicast routing
doesn't work, neither it doesn't show a neighbor nor
it register as neighbor in the next-hop router.  I
am using latest USAGI patch.

The kernel shows this message:

KERNEL: assertion (newskb->dst) failed at net/ipv6/ip6_output.c (113)

Does somebody knows the state of IPv6 multicast
routing in XORP and in Linux kernel?

I'm not a routing expert but would like to know what
exactly the 'enable-ip-router-alert-option-check'
option do?  I don't see a difference with true or
false.  If enabled is much verbose the output.

Thanks in advance.

PS. config.boot attached.
