Configuring Dynamic Subscriber Interfaces over GRE Tunnels

To configure a dynamic subscriber interface in an GRE tunnel configuration by using
packet detection, perform the following steps:
1.
2.
3.
4.
(Optional) Specify the source address of traffic that is destined for the primary
IP interface.
host1(config-subif)#ip source-prefix 192.168.2.20 255.255.255.0
Create a GRE tunnel interface.
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 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 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.
host1(config-subif)#ip auto-configure ip-subscriber
