Reconfigure IP Addresses
Tasks on all routers of workgroup 1 and 2
Disable RIPv2
router(config)# no router rip
Remove default route and default network on R4, R5
router(config)# no ip default network 45.0.0.0
router(config)# no ip route 0.0.0.0 0.0.0.0 45.0.0.5 (on R4)
router(config)# no ip route 0.0.0.0 0.0.0.0 45.0.0.4 (on R5)
Reconfigure workgroup X IP addresses via “console”
see next slides
enable RIPv2 again
router(config)# router rip
router(config-router)# version 2
router(config-router)# no auto-summary
otherwise RIPv2 summarizes at the IP address class boundary
router(config-router)# network < corresponding network number >
attention: specify these commands in exactly this sequence
verify topology using sh ip route
