HP VPN Firewall Appliances VPN Command Reference

Parameters
aging-time: Specifies the aging time for tunnel entries, in the range of 1 to 86400, in seconds.
Usage guidelines
This command is available only for tunnel interfaces operating in P2MP GRE tunnel mode.
If a device at the headquarters does not receive any packet from a branch before the aging time expires,
it removes the corresponding tunnel entry.
Too short a tunnel entry aging time might make tunnel entries age out too quickly, resulting in forwarding
failures of packets to the branch. Too long a tunnel entry aging time, on the other hand, might not be able
to make sure that the tunnel entry table gets updated in time. Set the aging time correctly as required.
Examples
# Set the P2MP tunnel entry aging time to 10 seconds.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] gre p2mp aging-time 10
gre p2mp backup-interface
Use gre p2mp backup-interface to specify a backup interface for a P2MP GRE tunnel interface.
Use undo gre p2mp backup-interface to restore the default.

Parameters
tunnel number: Specifies a backup interface. The number argument indicates the number of the tunnel
interface.

Examples
# Specify interface Tunnel 100 as the backup interface of the P2MP GRE tunnel interface Tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] gre p2mp backup-interface tunnel 100
