The value of vRtrLdpPeerPeIDMacFlushInterop specifies whether LDP will react to and send the non-standard PE-ID TLV (type 0x405) in an address withdraw message to effect 'flush-all-from-me' behavior. It is used to provide interoperability with other vendors that use this TLV for the MAC flush mechanism. Only FEC type 128 is currently supported. Peer LDP sessions must be manually configured towards the PEs requiring support for this TLV. When the value of vRtrLdpPeerPeIDMacFlushInterop is set to 'true', the receipt of an address withdraw message with empty MAC list including the non-standard TLV will trigger 'flush-all-from-me' behavior instead of the normal 'flush-all-but-mine'. The TLV will be included in any forwarding towards like-configured peers. When the value of vRtrLdpPeerPeIDMacFlushInterop is set to 'false', the non-standard TLV will be ignored and will not be included in any address withdraw messages sent to the peer. This object was obsoleted in release 13.0.
