tarko is right in suggesting that config typos can cause this sort of
thing, e.g.
--
router bgp 65555
address-family ipv6
redistribute static
ipv6 route 2001:418:3ef:1000::/6 2001:db8::1
--
Bear in mind that the "network" statement in the router bgp stanza on cisco
routers is only one of several methods of injecting prefixes into a bgp
rib, and is a method that many people routinely avoid because it means
duplication of configuration: each network statement requires a grounding
"ip{v6} route" statement in order to work stably. So why not combine the two?
