Configuring MLPPP Backhaul

DETAILED STEPS

	Command		Purpose
Step 1
	enable		Enables privileged EXEC mode.
			• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal		Enters global configuration mode.
	Example:

Step 3
	Router(config)# interface multilink		Creates a multilink bundle and enters the interface configuration mode:
	group-number		• group-number—Number of the multilink bundle.
	Example:		The example creates a multilink bundle 5.
			To remove a multilink bundle, use the no form of this command.
	Router(config)# interface
	multilink5
Step 4
	Router(config-if)# ip address		Assigns an IP address to the multilink interface.
	address [subnet mask]		• address— IP address.
	Example:		• subnet mask—Network mask of IP address.
	Router(config-if)# ip address		The example configures an IP address and subnet mask.
	10.10.10.2	255.255.255.0
Step 5
	Router(config-if)# exit		Exits configuration mode.
	Example:
	Router(config-if)# exit

Configuring MRRU

You should configure the local maximum received reconstructed unit (MRRU) of the multilink bundle to a value greater than or equal to 1508 bytes(or equal to the maximum packet length expected on the bundle at any point in time). The maximum MTU supported on the Cisco ASR 901 router is 1536, and MTU drops occur when the packet length is more than 1536.

Complete the following steps to configure MRRU:
