You can select an existing process ID for OSPF or AS number for EIGRP if one
has been previously configured. See
Protocols for DMVPN.
If no process IDs exist, or if you want to use a different one, you can configure a
process ID in this field.
Enter a new OSPF area ID for the network. This area ID is for the tunnel network.
SDM automatically adds the tunnel network to this process using this area ID.
This area shows the networks advertised using the selected routing protocol. If
you have already configured the routing protocol you specified in this wizard, the
networks that you specified to be advertised will appear in this list.
Add all the private networks that you want to advertise to the DMVPN peers using
this routing process. The DMVPN wizard automatically adds the tunnel network
to this process.
Network—A network address. You can enter the address of a specific network,
and use the wildcard mask to generalize the advertisement.
Wild card mask—(EIGRP and OSPF protocols) A bit mask that specifies how
much of the network address must match the address given in the network column.
This mask can be used to have the router advertise networks in a particular range,
based on the given address. A 0 bit specifies that the bit in the network address
must match the corresponding bit in the given network address.
For example, if the network address were 172.55.10.3, and the wildcard mask was
0.0.255.255, the router would advertise all networks starting with the numbers
172.55, not just the network 172.55.10.3.
Area—Shown when OSPF is selected, the OSPF area number for that network.
Each router in a particular OSPF area maintains a topological database for that
area.
Add—Click to add a network, or a group of networks, to advertise.
