Configuring the Group IP Address for Multilink PPP

D

When you deploy multilink PPP on your network, you must configure the group IP Address on each device under the multilink interface.

Multilink PPP is a protocol used to bundle multiple physical links together into a single logical link. The purpose of this is to increase the bandwidth and redundancy of the link, as well as provide load balancing across the links. In order to accomplish this, the links must be configured to act as a single link, with a single IP address and a single point of control.

To configure multilink PPP on a device, you must first create a multilink interface that includes the physical interfaces that you want to bundle together. This is typically done using the "interface multilink" command in the device configuration. Once the multilink interface is created, you can configure the group IP address under that interface using the "ip address" command.

For example, if you wanted to configure a multilink interface with a group IP address of 10.1.1.1 on a Cisco router, you would enter the following commands:

kotlinCopy code
interface multilink 1 ip address 10.1.1.1 255.255.255.0 

This would create a multilink interface with the number 1 and assign it the IP address 10.1.1.1 with a subnet mask of 255.255.255.0.

In conclusion, when deploying multilink PPP on your network, you must configure the group IP Address on each device under the multilink interface.
