R3303-HP HSR6800 Routers Layer 2 - WAN Command Reference

50
command to assign an IP address to the peer from the address pool of the specified domain through
AAA authentication, you can configure the command for the peer again. In this case, the original
assigned IP address can still work, and the newly assigned IP address is used when the original one is
released or used by a new PPP access.
This command does not take effect until the next IPCP negotiation. To make the remote address command
take effect, configure the remote address command before the ip address command.
Examples
# Specify the IP address to be assigned to the peer device through interface Serial 2/0/1 as 10.0.0.1.
<Sysname> system-view
[Sysname] interface serial 2/0/1
[Sysname-Serial2/0/1] remote address 10.0.0.1

Parameters
seconds: Interval (in seconds) for sending keepalive packets, in the range 0 to 32767. A value of 0
disables keepalive packet sending.
retries: Number of times for sending keepalive packets, in the range of 1 to 255.
Usage guidelines
Because a slow link takes a long period of time to transmit large packets, the sending and receiving of
keepalives might be delayed so long that one end cannot receive keepalive packets from the peer for a
specific number of keepalive periods and shuts down the link. To prevent this, set the interval for sending
keepalive packets to a relatively longer length of time.
When an interface is enabled with PPP, the interval for sending keepalive packets must be the same on
the two ends of the link.
