ESR Series Routers Operation Manual                                                          53 
To check the routing table, use the following command: 
esr# show ip route 
7.11  MLPP configuration 
Multilink PPP (MLPPP) is an aggregated channel that encompasses methods of traffic transition via 
multiple  physical  channels  while  having  a  single  logical  connection.  This  option  allows  to  enhance 
bandwidth and enables load balancing. 
 
 
Fig. 7.9—Network structure 
Objective: Configure MLPPP connection to the opposite side with IP address 10.77.0.1/24 via MXE 
device. 
 
Solution: 
 
Switch gigabitethernet 1/0/10 interface into E1 operation mode: 
 
esr# configure 
esr(config)# interface gigabitethernet 1/0/10 
esr(config-if-gi)# description "*** MXE ***" 
esr(config-if-gi)# switchport mode e1 
esr(config-if-gi)# switchport e1 slot 0 
esr(config-if-gi)# exit 
 
Enable interface e1 1/0/1, interface e1 1/0/4 into MLPPP 3 aggregation group: 
 
esr(config)#  interface e1 1/0/1 
esr(config-e1)# ppp multilink 
esr(config-e1)# ppp multilink-group 3 
esr(config-e1)# exit 
esr(config)#  interface e1 1/0/4 
esr(config-е1)# ppp multilink 
esr(config-е1)# ppp multilink-group 3 
esr(config-е1)# exit 
 
Configure MLPPP 3: 
 
esr(config)#  interface multilink 3 
esr(config-multilink)# ip address 10.77.0.1/24 
esr(config-multilink)# security-zone trusted 
esr(config-multilink)# exit 
esr(config)# exit 
Configuration changes will take effect when the following commands are executed: 
esr# commit 
Configuration has been successfully committed 
esr# confirm
