1.3.2.2 Configuration steps
Track detection is used in the configuration example. Alternatively, BFD can be used to associate with the wired link.
For detailed configuration, refer to the BFD configuration section in the Configuration Manual.
(1) Configure the wired link for track detection:
!Here, it is assumed that the IP address of the LNS corresponding to the wired link is 1.1.1.1.
Qtech(config)#ip rns 1
Qtech(config-ip-rns-icmp-echo)# icmp-echo 1.1.1.1 out-interface VLAN 1 next-hop 1.1.1.1
Qtech(config-ip-rns-icmp-echo)# timeout 3000
Qtech(config-ip-rns-icmp-echo)# frequency 3000
Qtech(config-ip-rns-icmp-echo)# ntime 3
Qtech(config)# track 1 rns 1
!Here, it is assumed that the IP address of the LNS corresponding to backup 4G link 1 is 2.2.2.2.
Qtech(config)#ip rns 2
Qtech(config-ip-rns-icmp-echo)# icmp-echo 2.2.2.2 out-interface Cellular 0/0
Qtech(config-ip-rns-icmp-echo)# timeout 3000
Qtech(config-ip-rns-icmp-echo)# frequency 3000
Qtech(config-ip-rns-icmp-echo)# ntime 3
Qtech(config)# track 2 rns 2
(2) Configure 4G dial-on-demand:
Qtech(config)#interface Cellular 0/0
Qtech(config-if-Cellular 0/0)# apply detect interface VLAN 1 track 1
Qtech(config-if-Cellular 0/0)# apply dial-on-demand
Qtech(config)#interface Cellular 1/0
Qtech(config-if-Cellular 1/0)# apply detect interface VLAN 1 track 1
Qtech(config-if-Cellular 1/0)# apply detect interface Cellular 0/0 track 2
