The above procedure is fine if you don‟t have a large OSPF network, as all OSPF routes will be
distributed to RIP. Instead, you can configure the Ethernet Routing Switch 8600 ASBR to distribute only a
default route instead of all OSPF routes to RIP.
Step 1 Configure a IP Prefix List with a Default Route
config ip prefix-list "default" add-prefix
0.0.0.0/0
Step 2 Configure a IP Prefix List with a Default Route
config ip route-policy "Policy_Default"
seq 1 create
config ip route-policy "Policy_Default"
seq 1 enable
config ip route-policy "Policy_Default"
seq 1 action permit
config ip route-policy "Policy_Default"
seq 1 match-protocol ospf
config ip route-policy "Policy_Default"
seq 1 set-injectlist "default"
config ip route-policy "Policy_Default"
seq 1 set-metric-type type1
Step 3 Configure a IP Prefix List with a Default Route
config ip rip interface
policy "Policy_Default"

10.1.1.41 out-
ERS 8600 / 8800 OSPF Technical Configuration Guide
This command creates an IP Prefix list named "default"
with address 0.0.0.0/0
These commands will create a Route Policy named
"Policy_Default" and will distribute the IP Prefix list
created in Step 1. Notice that ospf is selected for match-
protocol. Hence, the default route will only be advertised
via RIP if OSPF is up.
This command applies the Route Policy created in Step
2 to RIP interface 10.1.1.41.
