I have configured OSPF and RIP redistribution. OSPF area 0 is configured
between R2,R3,R4, and R5. They are connected through Frame relay, Hub-Spoke.
R5 is the hub. Physical interfaces are used on all routers. In OSPF area 0,
there are some /24, /26 and /30 networks, for example 170.150.5.0/24,
170.150.1.0/28, 170.150.3.0/30. R4 is connected to R6 through E0, the
network is 170.150.46.0/24. RIP is configured on R4 and R6. Redistribution
is configured between OSPF and RIP on R4.
My questions are:
Q1. The network between R2, R3, R4 and R5 is 170.150.1.0/28. Because of the Fr
ame
relay configuration, I saw the following routes on R4:
O 170.150.1.5/32 [110/64] via 170.150.1.5, 00:37:49, Serial0
O 170.150.1.3/32 [110/128] via 170.150.1.5, 00:37:50, Serial0
O 170.150.1.2/32 [110/128] via 170.150.1.5, 00:37:51, Se
These are the IP address configured on the serial interfaces of R2, R3, and R5.
IS this the normal behavior of FR physical interface configuration? Any thing
wrong with it?
Q2. The above mentioned /32 networks are redistributed into RIP domain. They
are showing up on R6 routing table. Why that? I thought that I should only se
e
/24 network redistributed into RIP domain from OSPF.
Q3. The /28 and /30 networks are not being redistributed into RIP domain as exp
ected.
There are two ways I know to fix the problem.
a. Define a static route with /24 mask on R4 and redistribute static;
b. Pass a default a default route to RIP domain by using "default information-o
riginate"
under RIP configuration.
Are there other way to do it?
Thanks.
