Hello Experts,
I have 2 Routers R4 and R5 connected via framerelay. I created 2 loopbacks in every router. I configured rip and i want the network 14.1.1.0 in R5 to be filtered out while sending out to R4. The issue is the another network13.1.1.0/24 is also getting filtered out. I used prefix list for filtering and i configured permit 0.0.0.0/32 along with the deny 14.1.1.0/24. Here is my config
R4:
interface Loopback0
ip address 10.1.1.1 255.255.255.0
interface Loopback1
ip address 11.1.1.1 255.255.255.0
interface Serial1/0
ip address 12.1.1.1 255.255.255.0
encapsulation frame-relay
frame-relay map ip 12.1.1.2 405 broadcast
router rip
version 2
network 10.0.0.0
network 11.0.0.0
network 12.0.0.0
no auto-summary
R5:
interface Loopback0
ip address 13.1.1.1 255.255.255.0
interface Loopback1
ip address 14.1.1.1 255.255.255.0
interface Serial1/1
ip address 12.1.1.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 12.1.1.1 504 broadcast
router rip
version 2
network 12.0.0.0
network 13.0.0.0
network 14.0.0.0
distribute-list prefix rip out
no auto-summary
ip prefix-list rip seq 5 deny 14.1.1.0/24
ip prefix-list rip seq 10 permit 0.0.0.0/32
Here is my routing table o/p
R4:
Rack1R4#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 1 subnets
