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.
Create a GRE tunnel interface.
For instructions, see the Configuration Tasks section in JUNOSe IP Services
Configuration Guide .
2.
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
3.
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
4.
Configure the primary IP interface to enable dynamic creation of subscriber
interfaces.
host1(config-subif)# ip auto-configure ip-subscriber
