The following example shows how to redistribute routes from BGP instance 15 into OSPF instance 1
using the policy OSPFv3-redist. The policy sets the metric type to type-2 for all redistributed routes.
BGP routes with a tag of 10 have their cost set to 100, and BGP routes with a tag of 20 have their OSPFv3
cost set to 200. Any BGP routes not carrying a tag of either 10 or 20 are not be redistributed into the
OSPFv3 link-state database.

set metric-type type-2
if tag eq 10 then
set extcommunity cost 100
elseif tag eq 20 then
set extcommunity cost 200
