Adding and Deleting Protocols for GRE Tunnels

The Bay Networks implementation of GRE tunneling supports IP and IPX

encapsulation. Use the BCC or Site Manager to add or delete a protocol for a GRE

tunnel.

Adding a Protocol to a GRE Tunnel

When you add a protocol to a tunnel, you are configuring its local logical

interface. This address is not visible to the network cloud that the tunnel passes

through.

Use the BCC or Site Manager to add a protocol to a GRE tunnel.

Using the BCC

You can use the BCC to add an IP or IPX protocol interface to a GRE tunnel.

Adding an IP Protocol Interface

To add an IP protocol interface to a GRE tunnel, navigate to the GRE tunnel

interface prompt (for example,

box; tunnels; gre/boston

) and enter:

ip address

mask

address

is the valid IP address at the local end of the tunnel expressed in

dotted-decimal notation.

mask

is the mask associated with the IP address.

For example, the following command adds the IP interface 9.9.9.1/255.255.255.0

to the tunnel boston:

gre/boston#

ip address 9.9.9.1 mask 255.255.255.0

For a complete description of IP interface configuration, see Configuring IP, ARP,

RIP, and OSPF Services.

Note:

You can configure OSPF on either a GRE tunnel’s physical interfaces

or its logical interfaces, but not on both. When configuring OSPF on a GRE

tunnel, disable MTU mismatch detection. If the MTU mismatch parameter is

enabled, an OSPF adjacency may fail to form over the tunnel.
