Multilink PPP Encapsulation
Multilink PPP Encapsulation
Cisco 700 series routers implement multilink PPP, which is available in Release 11.0(3) or later of Cisco IOS software. You can disable multilink PPP in the following two environments:
•You are connecting your Cisco 700 series router to a router running a Cisco IOS release prior to 11.0(3).
•You are connecting your Cisco 700 series router to a router running Cisco IOS Release 11.0(3) or later, and you have not configured multilink PPP on that router running Cisco IOS.
Use the set ppp multilink command at the system level to disable multilink PPP, as follows:
766> set ppp multilink off
Dynamic Routing Protocols
Cisco 700 series routers implement RIP Versions 1 and 2 and demand RIP. Demand RIP is not implemented in Cisco IOS software. If you are connecting your router to a router running Cisco IOS software, and you want to use a dynamic routing protocol, you must disable demand RIP.
Use one of the following set ip rip update commands to disable demand RIP:
766> set ip rip update periodic / snapshot
or
766> set ip rip update none
Note Setting the IP RIP update to periodic maintains the connection indefinitely. This might be a concern if it is not necessary to maintain the line 24 hours a day, 7 days a week; you are paying for connection time that you are not using.
