Multiple Standby
Interfaces
Take both interfaces Serial 1 and Serial 2 as the standby interface of interface
Serial 0, and use interface Serial 1 as a preference.
1 Enter the view of Serial 0.
[Router] interface serial 0
2 Set interfaces Serial 1 and Serial 2 as the standby interfaces, their priorities being
30 and 20, respectively.
[Router-Serial0] standby interface serial 1 30
[Router-Serial0] standby interface serial 2 20
Logical Channel Standby
Interface
In this example, set interface Serial 1 as the standby interface for an X.25 virtual
circuit on interface Serial 0.
1 Configure interface Serial 0 so that it encapsulates X.25 and specify its IP address
and X.121 address.
[Router]interface serial 0
[Router-Serial0]link-protocol x25
[Router-Serial0]ip address 1.1.1.2 255.0.0.0
[Router-Serial0]x25 x121-address 1
2 Match an X.25 virtual circuit on interface Serial 0 with logic channel 10.
[Router-Serial0]x25 map ip 2.2.2.3 x121-address 2 logic-channel 10
3 Enter the view of logic channel 10.
[Router-Serial0]logic-channel 10
4 Specify interface Serial 1 as the standby interface of this logic channel.
[Router-logic-channel10]standby interface serial 1
5 Set the time interval as 10 seconds for judging the logic channel as up.
[Router-logic-channel10]standby state-up 10
Multiple Standby
Interfaces with a Logic
Channe
l
Take both logic channel 3 on interface Serial 1 and interface Serial 2 as the
standby interfaces of logic channel 5 on interface Serial 0.
1 Configure that interface Serial 0 encapsulates X.25 and specify its IP address and
X.121 address.
[Router]interface serial 0
[Router-Serial0]link-protocol x25
[Router-Serial0]ip address 1.1.1.2 255.0.0.0
[Router-Serial0]x25 x121-address 1
2 Match an X.25 virtual circuit on interface Serial 0 with logic channel 5.
[Router-Serial0]x25 map ip 2.2.2.3 x121-address 2 logic-channel 5
3 Configure that interface Serial 1 encapsulates X.25 and specify its IP address and
X.121 address.
[Router-Serial0]interface serial 1
[Router-Serial1]link-protocol x25
[Router-Serial1]ip address 3.3.3.4 255.0.0.0
[Router-Serial1]x25 x121-address 3
4 Match logic channel 3 with an X.25 virtual circuit on interface Serial 1.
[Router-Serial1]x25 map ip 4.4.4.5 x121-address 4 logic-channel 3
