Step 1 Configure an IP address for each interface. This example assumes that you know the
configuration method and no details are provided here.
Step 2 Configure basic OSPF functions.
5.2 Configuring Basic OSPF Functions
details about the configuration, see the configuration files.
Step 3 Configure OSPF GTSM.
# On Router A, set the maximum valid TTL range for packets from Router A to other routers is
255 to 255.
[RouterA] ospf valid-ttl-hops 1
# On Router B, set the maximum valid TTL range for packets from Router B to other routers is
254 to 255.
[RouterB] ospf valid-ttl-hops 2
# On Router C, set the maximum valid TTL range for packets from Router C to other routers is
254 to 255.
[RouterC] ospf valid-ttl-hops 2
Step 4 Verify the configuration.
# Check whether OSPF neighbor relationships between routers are successfully established.
Take the display on Router C as an example. The neighbor relationship is Full, indicating that
the neighbor relationship is successfully established.
[RouterC] display ospf peer
Area 0.0.0.0 interface 192.168.2.2(Pos1/0/0)'s neighbors
Router ID: 1.1.1.1
State: Full
# On Router C, run the display gtsm statistics all command. You can view GTSM statistics on
Router C. The default behavior is pass, no illegal packets exist, and the number of discarded
packets is 0.
<RouterC> display gtsm statistics all
