Configuring Unnumbered IP Serial Interface Example
The following example configures an X.21-type, serial interface 1/0 as an unnumbered serial
interface. Serial 1/0 is directed to use the IP address of FastEthernet port 1.
XSR(config)#interface fastethernet 1
XSR(config-if<F1>)#ip address 192.168.1.1 255.255.255.0
XSR(config-if<F1>)#no shutdown
XSR(config)#interface serial 1/0
XSR(config-if<S1/0>)#media-type x21
XSR(config-if<S1/0>)#encapsulation ppp
XSR(config-if<S1/0>)#ip unnumbered fastethernet 1
XSR(config-if<S1/0>)#no shutdown
XSR#copy running-config startup-config
Configuring OSPF Example
The following is a sample configuration of OSPF which adds three networks to OSPF areas
including stub and NSSA areas, sets the retransmit interval on interface FastEthernet 1 to 9
seconds, specifies the cost of sending traffic on interface Serial 1/0 to 64, and redistributes static
routes into OSPF:
XSR(config)#interface FastEthernet 1
XSR(config-if<F1>)#no shutdown
XSR(config-if<F1>)#ip address 192.168.1.100 255.255.255.0
XSR(config-if<F1>)#ip ospf retransmit-interval 9
XSR(config-if<F1>)#interface FastEthernet 2
XSR(config-if<F2>)#no shutdown
XSR(config-if<F2>)#ip address 156.57.99.3 255.255.255.0
XSR(config)#interface serial 1/0
XSR(config-if<S1/0>)#no shutdown
XSR(config-if<S1/0>)#media-type V35
XSR(config-if<S1/0>)#encapsulation ppp
XSR(config-if<S1/0>)#ip address 154.68.1.47 255.255.255.0
XSR(config-if<S1/0>)#ip ospf cost 64
XSR(config)#router ospf 1
XSR(config-router)#network 192.168.1.0 0.0.0.255 area 0.0.0.10
XSR(config-router)#network 154.68.1.0 0.0.0.255 area 0
XSR(config-router)#area 10 nssa default-information-originate
XSR(config-router)#network 156.57.99.3 255.255.255.0 area 1
XSR(config-router)#area 1 stub
XSR(config-router)#redistribute static
