What is the administrative distance of the null0 route? I assume it must be the same as static (ad of 5 on IOS?), or it would not try to load-share across the two routes.

You can check this from the output of  show ipv6 route which will give you the IPv6 roting table.

Can you modify the admin distance on your static route to be lower than the default?  I know you can make it higher; don't recall on lower.

The default administrative distance of static route should be 1. You should see that in the routing table. You can set the AD between 1 and 254. Routing protocols will also have their default ADs (EIGRP=90, OSPF=110, RIP=120...). A directly connected net shows zero.

I assume it's the numbers in the square brackets? eg, [0/0]. The null route appears to have the same values as the static routes in that case....
Code: [Select]
#show ipv6 route
IPv6 Routing Table - default - 8 entries
Codes: C - Connected, L - Local, S - Static, U - Per-user Static route
       B - BGP, HA - Home Agent, MR - Mobile Router, R - RIP
       D - EIGRP, EX - EIGRP external, ND - Neighbor Discovery
       O - OSPF Intra, OI - OSPF Inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
S   ::/0 [1/0]
     via Dialer1, directly connected
C   2001:44B8:4031:B7::/64 [0/0]
     via Dialer1, directly connected
L   2001:44B8:4031:B7:CEEF:48FF:FEAF:ECB8/128 [0/0]
     via Dialer1, receive
S   2001:44B8:4126:C600::/56 [1/0]
     via Null0, directly connected
S   2001:44B8:4126:C600::/57 [1/0]
     via 2001:44B8:4126:C600::F0
C   2001:44B8:4126:C600::/64 [0/0]
     via Vlan1, directly connected
L   2001:44B8:4126:C600::1/128 [0/0]
     via Vlan1, receive
