1.0.0.0/8, auto-summary

1.1.1.0/24, cost 0, nexthop 1.1.1.1, RIP-interface

1.1.2.0/24, cost 0, nexthop 1.1.2.1, RIP-interface

1.1.3.0/24, cost 1, nexthop 1.1.1.2

1.1.4.0/24, cost 2, nexthop 1.1.1.2

1.1.5.0/24, cost 2, nexthop 1.1.1.2

The output shows that only one RIP route reaches network 1.1.5.0/24, with the next hop as Switch
B (1.1.1.2) and a cost of 2.

, Switch A and Switch B run OSPF, Switch D runs RIP, and Switch C runs OSPF and

RIP. Configure RIP to redistribute OSPF routes on Switch C so Switch D can learn routes destined for

networks 10.1.1.0/24, 10.2.1.0/24, 10.5.1.0/24, and 10.6.1.0/24.
To reduce the routing table size of Switch D, configure route summarization on Switch C to advertise only
the summary route 10.0.0.0/8 to Switch D.

Configuration procedure

1.

Configure IP addresses for interfaces. (Details not shown.)

2.

Configure basic OSPF:
# Configure Switch A.

<SwitchA> system-view

[SwitchA] ospf

[SwitchA-ospf-1] area 0

[SwitchA-ospf-1-area-0.0.0.0] network 10.5.1.0 0.0.0.255

[SwitchA-ospf-1-area-0.0.0.0] network 10.2.1.0 0.0.0.255

[SwitchA-ospf-1-area-0.0.0.0] quit

# Configure Switch B.

<SwitchB> system-view

[SwitchB] ospf

[SwitchB-ospf-1] area 0

[SwitchB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
