Is apply attribute of BGP convergence policy valid?
V5 includes all VRP5.1 and 5.3.
orgin-policy is to decide which routes join in convergence (if-match sentence is valid and apply sentence is invalid);
suppress-policy decides which routes are suppressed. It is suppressed through policy (if-match sentence is valid and apply sentence is invalid.);
attribute-policy sets attribute for convergence route. If if-match is set, the attribute is not applied if it does not pass. Convergence route is still created.
