3Com 10014299 manual Configure RouterA Configure interface Ethernet, Configure interface Serial

Typical X.25 Configuration Example 235

Note that you must configure a virtual IP address and two static routes on interface Serial 1 to deceive the router because two lines connected to the same peer exist in router RouterC. Thus load balancing can be achieved because router RouterC will deem that there are two routes connected to network segment 10.1.1.0.

1Configure RouterA

aConfigure interface Ethernet 0.

[Router]interface ethernet 0 [Router-Ethernet0]ip address 10.1.1.1 255.255.255.0

bConfigure interface Serial 0.

[Router-Serial0]x25 x121-address 1111

[Router-Serial0]ip address 1.1.1.1 255.255.255.0

[Router-Serial0]x25 map ip 1.1.1.3 x121-address 3333

[Router-Serial0]x25vc-per-map 2
