Cisco IOS XR Carrier Grade NAT Configuration Guide for the Cisco CRS Router, Release 5.2.x
Configuring Dual Stack Lite Instance
Purpose
Enters the address family IPv6 configuration mode.
Specifies the ServiceApp on which IPv6 traffic enters
and leaves.
Configures the TCP protocol session.
This command configures the timeout value in
seconds for ICMP,TCP or UDP sessions for a service
instance. For TCP and UDP, you can configure the
initial and active session timeout values. For ICMP,
there are no such options. This configuration is
applicable to all the IPv4 addresses that belong to a
particular service instance. This example configures
the initial session timeout value as 90 for the TCP
session.
Configures the adjustment MSS value as 1100.
Configures the external-logging facility for the DS
LITE instance named dsl1 and enters the external
logging configuration mode.
Configures the logging server information for the IPv4
address and port for the server that is used for the
netflow-v9 based external-logging facility and enters
external logging server configuration mode.
Configures the netflow server address and port number
to use for netflow version 9 based external logging
facility for DS LITE instance.
