[Router]ip route-static 129.11.0.0 255.255.0.0 202.38.161.2

 

Configurations of router B and router C are omitted here. For fault diagnosis and

 

troubleshooting of sub-interface, please see chapters in Operation Manual - Link

 

Layer Protocol and Operation Manual - Network Protocol in this manual.

 

 

Standby Center Logic

The standby center not only provides mutual backup between respective

Channel

interfaces, but also chooses a certain virtual circuit belonging to X.25 or frame

 

relay as the main interface or standby interface of the standby center. Please see

 

relevant chapters in Operation Manual – Reliability for details about the standby

 

center.

 

To facilitate configuration, the user can specify relevant logic channel for the

 

above-mentioned virtual circuit and configure working parameters of the standby

 

center in the logic channel.

example, fault diagnosis and troubleshooting oriented to the configurations of the

 

standby center logic channel, please see Operation Manual – Reliability.

 

 

Virtual-Template and

Virtual-template as the name implies, is a template used to configure a virtual

Virtual Interface

interface, mainly used in VPN and MP.

 

After setting up the connection of VPN session, it is necessary to create a virtual

 

interface to exchange data with the opposite end. At this times configuration and
