Configuring Persistent Backup For Multiple Connections - HP 7102dl - ProCurve Secure Router Configuration Manual

N o t e
If your router uses routing protocols to learn routes to the remote destination,
you must enter an administrative distance for the floating static route that is
higher than the administrative distance for the routing protocol. For example,
the administrative distance for OSPF routes is 110, so you could enter this
command:
ProCurve(config)# ip route 192.168.64.0 /18 ppp 2 120

Configuring Persistent Backup for Multiple Connections

A single analog or ISDN module can back up any number of connections,
although, of course, it can only actively back up one failed connection at a
time. To enable backup on multiple connections simply configure a backup
dial list for each connection.
Special considerations for backing up multiple connections include:
setting a connection's priority
configuring multiple backup interfaces
Priority. A connection's relative priority determines which connection a
backup module serves when more than one connection goes down at a time.
By default, every connection for which backup has been configured has a
priority of 50. The router will back up the connection with the higher priority
value.
In a Frame Relay network, a backup line can only provide a connection for one
PVC at a time. If your router has a Frame Relay WAN connection with multiple
PVCs, you should set the highest priority for the most mission critical PVC.
To set the priority for a connection, move to the logical interface configuration
mode context for that connection. Enter this command:
Syntax: backup priority <priority>
A connection's priority can be between 0 and 100, with 100 the highest priority.
Multiple Backup Interfaces. You can use the same backup interface for
more than one connection, but you should configure a separate backup
interface for each connection when using authentication. A PPP interface can
only store one username and password in its database. If the peers for the
different connections have different usernames, you need to create and
configure a separate backup PPP interface for each. Map the backup interface
to the primary interface in the primary interface's backup dial list.
