Hi,
I think that there are two problems, BGP shouldn't be sending an
update with with a nexthop of zero and the test shouldn't be expecting
to see a nexthop of zero. I would expect that the nexthop should be
the IP address of the router. The test is failing to set a nexthop
address for IPv6 as it does for IPv4, it looks like in the past an
IPv6 address of zero passed through the system and now BGP is no
longer allowing it.
My suggestion is to log this as a bug and add this to the
TEST_NOT_FIXED variable and remove it from TESTS.
Atanu.
