Specifying Tunnel Destination; Assigning Network Address To Tunnel Interface - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
Note:
The same source address and destination address cannot be configured on two or
more tunnel interfaces encapsulated with the same protocol.
The source command configures actual physical interface address or actual
physical interface. In addition, the network address of tunnel interface also needs
configuring by using the ip address command in tunnel interface view.

3.2.4 Specifying Tunnel Destination

After the creation of a tunnel interface, the destination address of the tunnel, that is, IP
address of the actual physical interface receiving GRE packets, also needs to be
specified. A tunnel is uniquely identified by one source address and one destination
address. These configurations are required on both ends of the tunnel, with the source
address at one end being the destination address at the other end and vice versa.
Perform the following configuration in tunnel interface view.
Table 3-4 Specify destination address of the tunnel
Set destination address of the tunnel.
Delete the destination address of the tunnel.
Note:
The destination command sets IP address of actual physical interface. In order to
support dynamic routing protocols, network address of tunnel interface also needs
configuring.

3.2.5 Assigning Network Address to Tunnel Interface

You must assign addresses to the interfaces at the ends of a tunnel. The assigned
addresses can be private ones but they must belong to the same network segment.
Perform the following configuration in Tunnel interface view.
Table 3-5 Assign network address to a tunnel interface
Assign an IP address to the tunnel
interface.
