RIP basic config on JunOS, IOS, IOS-XR

topology:

1. Configure rip protocol in JunOS1, R1, IOS-XR.

root@test# top show protocols {     rip {         group RIP {             export PERMIT;             neighbor em0.0;         }     } } policy-options {     policy-statement PERMIT {         then accept;

R1#show run | se router router rip  version 2  network 1.0.0.0  network 10.0.0.0  no auto-summary

RP/0/0/CPU0:ios#show run router rip Sat Mar 14 20:57:47.301 UTC router rip  interface Loopback0  !  interface GigabitEthernet0/0/0/2  ! !

root@test# run show route protocol rip

inet.0: 8 destinations, 8 routes (8 active, 0 holddown, 0 hidden)

+ = Active Route, - = Last Active, * = Both

                    > to 10.1.13.1 via em0.0

                    > to 10.1.13.1 via em0.0

                    > to 10.1.13.1 via em0.0

2. Config filtering network 1.1.1.0/24 in routing table JunOS and IOS-XR

root@test# top show protocols {     rip {         group RIP {             export PERMIT;             import DENY_NETWORK_LO;             neighbor em0.0;         }     } } policy-options {     prefix-list DENY_L0_R1 {         1.1.1.0/24;     }     policy-statement DENY_NETWORK_LO {         term TERM1 {             from {                 prefix-list DENY_L0_R1;             }             then reject;         }         term TERM2 {             then accept;         }     } }

RP/0/0/CPU0:ios#show running-config prefix-set DENY_L0_R1   1.1.1.0/24 end-set ! route-policy DENY_NETWORK_LO   if destination in DENY_L0_R1 then     drop   endif   pass end-policy ! router rip  interface Loopback0  !  interface GigabitEthernet0/0/0/2  !  route-policy DENY_NETWORK_LO in !

Let's verify routing table:

root@test# run show route protocol rip

inet.0: 7 destinations, 7 routes (7 active, 0 holddown, 0 hidden)

+ = Active Route, - = Last Active, * = Both

2.2.2.0/24         *[RIP/100] 01:13:24, metric 3, tag 0

                    > to 10.1.13.1 via em0.0

10.1.12.0/24       *[RIP/100] 01:14:18, metric 2, tag 0

                    > to 10.1.13.1 via em0.0

224.0.0.9/32       *[RIP/100] 00:11:37, metric 1

                      MultiRecv

__juniper_private2__.inet.0: 1 destinations, 1 routes (0 active, 0 holddown, 1 hidden)
