Configuring Backup WAN Connections
Quick Start
3-108
8. Move to the logical interface for the primary connection.
Syntax: interface <interface ID>
For example:
ProCurve(config)# interface frame-relay 1.102
9. Add the remote site's telephone number to the backup call list.
Syntax: backup number <remote site's LDN> analog ppp <backup interface
number>
For example:
ProCurve(config-fr 1.102)# backup number 5552222 analog ppp 2
10. Set the backup call mode.
Syntax: backup call-mode [originate | answer | answer-always | originate-
answer | originate-answer-always]
For example, the router connects to the remote site through a Frame
Relay network. The connection on one side might still be up when the
other goes down, so you set the call mode to originate answer always.
ProCurve(config-fr 1.102)# backup call-mode originate-answer-always
11. Disable backup for the days and times you do not want to provide backup.
Syntax: no backup schedule day <day>
Syntax: backup schedule disable-time <hh:mm:ss>
Syntax: backup schedule enable-time <hh:mm:ss>
Enter times in 24-hour clock format. For example:
ProCurve(config-fr 1.102)# no backup schedule saturday
ProCurve(config-fr 1.102)# backup schedule disable-time 18:00:00
ProCurve(config-fr 1.102)# backup schedule enable-time 8:00:00
12. If you are using static routing, add a floating static route to the remote site.
Syntax: ip route <remote network A.B.C.D> [<remote subnet mask> | /<prefix
length>] [<remote backup A.B.C.D> | ppp <backup interface number>] [<admin-
istrative distance>]
Set the administrative distance higher than the route through the primary
connection so that the router will only add the backup route to its table
if the primary connection fails. For example, enter:
ProCurve(config)# ip route 192.168.3.0 /24 ppp 2 2
