If you want to install different security policies for different policy indexes use the Check Point FireWall 1 command line interface to enter the following command fw load conf lt config_file gt pol lt policy_index_number gt lt router_name gt 308663 15 7 Rev 00 Release Notes for BayRS Version 15 7 0 0 For example the following command specifies that the system install the security policy in the configuration file drop_ftp on policy index number 1 on the router named asn1 fw load conf drop_fip pol1 asn1 Upgrading IP Route Filters If you have configured IP route filters and then disabled those filters rather than deleted them when you upgrade to Version 15 7 0 0 from a version earlier than 14 00 the filters will be re enabled You must disable the filters again after the upgrade is complete If you do not want to use the filters you may want to delete them before you upgrade BayRS to Version 15 7 0 0 Upgrading L2TP Configurations If you have a BayRS Version 12 10 configuration file that includes L2TP operating on a router using BayRS Version 15 7 0 0 the router automatically upgrades the assigned user network addresses to L2TP IP interface addresses L2TP IP interface addresses are internal to the router When communicating with the remote user the router associates the user s IP address with an L2TP IP interface address that you configure The user network addresses assigned to Version 12 10 apply
4. If there is a loss of signal to a router during a period of heavy traffic the ATM interface on the router might stop functioning If the ATM interface stops functioning you must reboot the router to recover On the ARE BayRS does not release virtual channel connections when they time out To maintain the availability of VCCs for new activities configure a LAN emulation client LEC other than the router to release the inactive VCCs ATM signal ports on a switch and router must have the same version number If you are using a switch with ATM signal ports set to V3 1 be sure to set the signaling setting on the router to V3 1 to prevent a conflict between the two devices If you accept the default setting of V3 0 for the router the router faults repeatedly until you change the setting to V3 1 If a context is deleted and re created in the same BCC source file unexpected results may occur The create delete MIB is set to deleted when issuing the deletion but it is not reset to created when reconfiguring the context 46 308663 15 7 Rev 00 Release Notes for BayRS Version 15 7 0 0 BGP The following limitations exist for BGP services in BayRS e Ifyou specify a router interface address as the BGP peer address and that address is included in the network list for an announce policy configured on that router BGP will not announce that network to a BGP peer even if the remote peer is configured to accept that network from the pee

M This section describes compatibility issues that exist when running Protocol Independent Multicast PIM in a network that consists of both Nortel Networks routers and non compliant implementations of PIM on routers Note The term non compliant router is used in the following sections to indicate routers such as Cisco routers that run implementations of PIM that do not comply with all elements of RFC 2362 Nortel Networks routers can be configured for compatibility with non standard implementations of PIM at the RFC2362 Non Compatibility parameter using Site Manager For additional information see Enabling and Disabling Router Compatibility with RFC 2362 in Configuring IP Multicasting and Multimedia Services Fragment Tagging in Bootstrap Messages In a PIM network in which Nortel Networks and non compliant routers interoperate a non compliant router sends bootstrap packets that contain a fragment tag set to a zero value When the Nortel Networks router receives these packets it treats them as duplicate packets and immediately drops them To enable a Nortel Networks router to accept bootstrap packets from a non compliant router select the PIM _BSR_ZERO FRAGMENT _ TAG option at the RFC2362 Non Compatibility parameter using Site Manager 38 308663 15 7 Rev 00 Release Notes for BayRS Version 15 7 0 0 Non Compliant Router Drops RP Advertisement with Zero Prefix If you configure a non compliant router to se
