Multilink PPP
Use this page to set up Multilink PPP on the RASExpress server. The Multilink PPP
protocol bonds multiple ports to one IP address for greater bandwidth. When you are
done, click Submit to save the information and return to the Configuration of Server
menu, or click Reset to cancel your changes.
Note: RASExpress has MultiChassis Multilink support, which enables the bundling
of multilink connections across different RASExpress servers. All MultiChassis
Multilink servers must have IP and PPTP turned on to enable the servers to talk to
each other. Also, all MultiChassis Multilink servers should point to the same RADIUS
or TACACS+ server.
Multilink PPP
Select Enabled to enable Multilink PPP (MLPPP) support on the RASExpress server.
RASExpress supports Multilink PPP for both analog and ISDN channels.
Group EPD
Identifies the bundle group that the RASExpress server belongs to. The EPD (End
Point Descriminator) is an arbitrary four-byte hexadecimal value. By default
RASExpress initializes it to the IP address of its Ethernet interface. However, all
servers that belong to the same bundle group should have the same EPD.
Bundle Server IP Address
Type the IP address of the Bundle Server. The Bundle Server is the RASExpress 5.40
or later server chosen to manage the multichassis multilinks. It can be any RASExpress
5.40 or later server on the network, but the optimal server is the one that is equidis-
tant from all RASExpress servers in the bonding group. If the servers are on different
networks, then the hop count from the Bundle Server to all the other servers should
be more or less equal. Alternately, the one that is least busy can function as the Bundle
Server.
