Redistribute Connected

Scenario to verify RIP redistribute connected functionality with metric configuration and route-map filtering options.

Test RIP Default Metric With Default Value

Description

Test RIP redistribute connected metric with the default value (metric 1). When metric is not explicitly configured, RIP uses metric 1 by default. DUT0 redistributes the connected route 10.10.10.0/24 with the default metric. DUT1 learns this route with metric 2 (incremented by 1 hop). The route is installed in the routing table and connectivity is verified with ping.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 10.10.10.1/24
set interfaces ethernet eth0 address 10.1.1.100/24
set protocols rip network 10.1.1.0/24
set protocols rip redistribute connected
set protocols rip timers update 5
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.1.1.50/24
set protocols rip network 10.1.1.0/24
set protocols rip timers update 5
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Attention

Verify that DUT1 learns route 10.10.10.0/24 with next-hop 10.1.1.100 and metric 2

Step 3: Run command protocols rip show at DUT1 and check if output matches the following regular expressions:

R\(n\) +10.10.10.0/24\s+10.1.1.100\s+2\s+10.1.1.100

Test RIP Metric 16 Route Not Announced

Description

Test RIP redistribute connected metric 16 - route is not announced. When DUT0 redistributes 10.10.10.0/24 with metric 16 (infinity), the route is not announced to neighbors because it is already unreachable at the source. DUT1 does not see the route in RIP database, does not install it in routing table, and ping fails.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 10.10.10.1/24
set interfaces ethernet eth0 address 10.1.1.100/24
set protocols rip network 10.1.1.0/24
set protocols rip redistribute connected metric 16
set protocols rip timers update 5
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.1.1.50/24
set protocols rip network 10.1.1.0/24
set protocols rip timers update 5
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Attention

Verify that DUT1 does not see route 10.10.10.0/24 in RIP database

Step 3: Run command protocols rip show at DUT1 and expect this output:

Step 4: Expect a failure in the following command: Ping IP address 10.10.10.1 from DUT1:

admin@DUT1$ ping 10.10.10.1 count 1 size 56 timeout 1

Test RIP Redistribute Connected With Route-Map

Description

Test RIP route redistribution with route-map filtering between two routers. DUT0 has two dummy interfaces (dum0 and dum1), but only dum0 matches the route-map INTERNAL filter. This validates that only matching routes are advertised while non-matching routes (dum1) are filtered out.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 10.10.10.1/24
set interfaces dummy dum1 address 10.20.20.1/24
set interfaces ethernet eth0 address 10.1.1.100/24
set protocols rip network 10.1.1.0/24
set protocols rip redistribute connected route-map INTERNAL
set protocols rip timers update 5
set protocols route-map INTERNAL rule 1 action permit
set protocols route-map INTERNAL rule 1 match interface dum0
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.1.1.50/24
