Note that the configuration shown above is for a multicast interface. For
an NBMA interface, the configuration in /etc/gated.conf would be
set up as follows:
# Router A Configuration (non-stub area)
OSPF yes {
area 0.0.0.1 {
interface 193.2.1.35 nonbroadcast cost 5 {
routers {
193.2.1.33 eligible ;
} ;
priority 5 ;
enable ;
hellointerval 5 ;
routerdeadinterval 20 ;
retransmitinterval 10 ;
pollinterval 20 ;
} ;
} ;
} ;
NOTE If you use IP multicasting in an area, every router and all intermediate
network devices in that area must support IP multicasting.
B: Area Border Router
Set up /etc/gated.conf as follows:
OSPF yes {
defaults {
cost 5 ;
} ;
area 0.0.0.1 {
interface 193.2.1.33 cost 5 {
priority 15 ;
enable ;
hellointerval 5 ;
routerdeadinterval 20 ;
retransmitinterval 10 ;
} ;
} ;
area 0.0.0.2 {
interface 193.2.1.17 cost 5 {
priority 15 ;
enable ;
hellointerval 5 ;
routerdeadinterval 20 ;
retransmitinterval 10 ;
} ;
} ;
