This field contains bit flags which indicate whether PRVT-LDP supports LDP Policy and if per FEC policy optimization is to be used.

The supported bit flags are defined below. - policySupported - perFecOptimizationSupported - suppressAddressPolicy.

The policySupported flag indicates that PRVT-LDP will enforce policy decisions made by the user through a number of user exits. If this flag is not set PRVT-LDP will not call policy user exits.

The perFecOptimizationSupported flag indicates that PRVT-LDP provides policy on a per FEC basis as opposed to a per FEC per session basis. This results in policy user exits only being called once per FEC. This field is only significant if the policySupported flag is set. This feature is used to reduce the number of calls to the Policy User Exits particularly when a change in Policy is being implemented.

If the perFecOptimizationSupported flag is not set then PRVT-LDP Path Manager enforces policy on a per FEC per peer basis.

If this flag is set policy is enforced on a per FEC basis and the same policy decision is assumed to apply for all peers.

The suppressAddressPolicy flag if set prevents PRVT-LDP from performing any Policy processing on receipt of a Address or Address Withdraw message from a peer.

If this field is not set then its default value is determined by the RCP_USER_DO_POLICY compile time flag.

Changes to the value of policy_support_flags are not permitted whilst the MIB row is active.
