The remote VPWS site ID of the PW to bind the AC to, or zero if not specified. This is only used if the pseudowire (PW) is created as a result of BGP auto-discovery, that is if vpwsBindCfgPwBindType = lclRmtVeId. If vpwsBindCfgPwBindType = lclRmtVeId then the AC is bound to a PW that connects the local VPWS site (vpwsConfigLocalSiteID) to the remote VPWS site, using auto-discovery to determine the remote PE router that hosts the remote VPWS site. This remote VPWS site ID should match the local VPWS site ID configured on the remote PE router. The valid range for VPWS site IDs depends on whether LDP or BGP signaling is used. - For LDP signaling (vpwsConfigSigType = ldp) the valid range is 1-4294967295 (4 bytes). - For BGP signaling (vpwsConfigSigType = bgp) the valid range is 1-65535 (2 bytes). Changing this value will cause an interruption to data flow from this AC onto the VPWS.
