Hello,

On MX router i'm tring advertise ::/0 to v6 peers. I have active,
static default route into my upstream direction. Other v6 routes are
advertised to my client but not ::/0
I removed bgp6 export policy but still no success

any help will be appreciated
thanks,
Pedro

My output

# show protocols bgp group EXTERNAL_UPSTREAM_IPV6
type external;
local-address 2a00:cccc:cccc:1::42;
import import_IPV6;
export export_IPV6;
peer-as 11114;
neighbor 2a00:cccc:cccc:1::41;



# show protocols bgp group CLIENT_1_EXTERNAL_IPV6
type external;
local-address 2a03:aaaa:0:bb50::1;
peer-as 911;
neighbor 2a03:aaaa:0:bbbb::6 {
multihop;
family inet6 {
unicast;
}
}



# show routing-options rib inet6.0
static {
route ::/0 next-hop 2a00:cccc:cccc:1::41;
}

# run show route ::/0

Default BGP policy doesn't imply that static routes are spontaneously allowed anyway, so removing it is useless.
Your bgp export policy is probably fucked up but unfortunately you didn't show it.
