83.3 Command Examples
In this example, the OLT ( A ) is an Area Border Router (ABR) in an OSPF network.
Figure 281 OSPF Network Example
This example enables OSPF on the OLT, sets the router ID to 172.16.1.1 , configures an OSPF area ID as
0.0.0.0 (backbone) and enables simple authentication.
passive-iface < ip-addr/bits >
Sets the interface to be passive.
A passive interface does not send or receive
hello packets in the OSPF network. If hello
packets can’t be sent out from the passive
interface, a neighbor relationship won’t be
formed. Thus, this prevents attackers to have
access in the OSPF network.
C 13
no passive-iface < ip-addr/
bits >
Sets the interface to not be passive. C 13
summary-address < ip-addr >
< mask >
Sets a summary address which is a network IP
address used to cover more than one network
routing entry in order to reduce the routing table
size. C 13
no summary-address < ip-add >
< mask >
Removes a summary address. C 13
no router ospf
Disables OSPF on the OLT. C 13
