Menu Descriptions MX410/MX412 System Manual5-32 PRELIMINARY 61189500L1-1BPPP BCP/IPCP MenuPoint-to-Point Protocol (PPP) is commonly used for LAN extension and Remote managementconnectivity. PPP can use one of two upper layer protocols:ï BCP (Bridge Control Protocol): This protocol routes packets based on MAC addresses andallows broadcast traffic to be passed over the PPP link(s). This protocol enables true LANExtension to be completed. Any device on the LAN can communicate with any other devicewith the least amount of configuration by the user.ï IPCP (IP Control Protocol): This protocol is used to for the user to assign an IP address toeach interface of the MX410/MX412. This enables dynamic routing of packets based onthe IP address and prohibits broadcast traffic from being passed over the PPP link(s). Thisprotocol requires more IP knowledge and configuration of each device on the network toensure proper IP routing, Default gateway configuration, as well as avoiding conflicts ofnetworks and DHCP configurations. When IPCP is enabled, RIP v2 is the routing protocolused by the MX410/MX412.If using PPP, the T1/FT1 carrying the PPP link should be configured to ESF and B8ZS.CAUTIONOnly one PPP link can be connected between two devices. If morethan one PPP link is connected between two devices, it creates anEthernet LOOP and causes a Packet Storm across the entireEthernet network.The PPP BCP/IPCP menu shown in Figure 5-20 is used to provision the PPP ports.Figure 5-20.
