Configuring MMP
Configuring MMP
If you have multiple access servers stacked together to provide a frontend for receiving access calls,
you can configure Multichassis Multilink Point-to-Point Protocol (MMP) so that Multilink PPP
(MP) call processing can be offloaded to other access servers.
MMP support on a group of access servers requires that each access server be configured to support:
• Stack Group Bidding Protocol (SGBP)
• Virtual templates used for cloning interface configurations to support MMP
• Multilink PPP

Step Command Purpose
1 5300> enable
Password: <password>
5300#
Enter enable mode (also called
privileged EXEC mode).
Enter the password.
You have entered enable mode when the
prompt changes to
5300#.
2 5300# configure terminal
Enter configuration commands, one per line. End
with CNTL/Z.
5300(config)#
Enter global configuration mode. You
have entered global configuration mode
when the prompt changes to
5300(config)#.
3 5300(config)# sgbp group stackq
Create a stack group and assign this
access server to it.
4 5300(config)# sgbp member systemb 172.16.188.2
5300(config)# sgbp member systemc 172.16.189.254
Specify the host name and IP address of
the peer member of the stack group. In
this example there are two peers:
systemb and systemc.
5 5300(config)# sgbp seed-bid offload
Set the bidding level for a stack group
member. Offload indicates that this
access server is a relatively higher
powered stack group member. The
access server will function as an offload
server and host the master bundle
interface.
6 5300(config)# multilink virtual-template number
Define a virtual template
1
for the stack
group.
7 5300(config)# ip local pool default ip-address
Specify an IP address pool by using any
pooling mechanism—for example, IP
local pooling or DHCP
2
pooling.
8 5300(config)# interface virtual-template number
Create a virtual template interface, and
enter interface configuration mode.
9 5300(config-if)# ip unnumbered ethernet 0
If dialers are not configured on the
physical interfaces, identify the virtual
template interface type and number on
the LAN.
10 5300(config-if)# encapsulation ppp
Enable PPP encapsulation on the virtual
template interface.
