Configuring Dynamic Subscriber Interfaces over GRE Tunnels

Copyright © 2010, Juniper Networks, Inc.
To configure a dynamic subscriber interface in an GRE tunnel configuration by using
packet detection, perform the following steps:
Create a GRE tunnel interface.
1.
For instructions, see the Configuration Tasks section in JunosE IP Services Configuration
Guide .
Create the primary IP interface by assigning an IP address and mask to the bridged
2.
Ethernet interface (or make it unnumbered).
host1(config-subif)#ip address 192.168.2.20 255.255.255.0
Configure the packet detect feature and specify that IP automatically detect packets
3.
that do not match any entries in the demultiplexer table.
host1(config-if)#ip auto-detect ip-subscriber
Configure the primary IP interface to enable dynamic creation of subscriber interfaces.
4.
host1(config-subif)#ip auto-configure ip-subscriber
(Optional) Specify the IP inactivity timer.
5.
host1(config-subif)#ip inactivity-timer 100
(Optional) Specify the source address of traffic that is destined for the primary IP
6.
interface.
host1(config-subif)#ip source-prefix 192.168.2.1 255.255.255.0
Figure 27 on page 618 shows the interface stack built for this configuration.
