Redistribute Connected Route-Map

Test to verify RIPng protocol route-map filtering functionality for IPv6 route redistribution. This test validates that only routes matching the route-map criteria are advertised to neighbors, while non-matching connected routes are filtered out. Demonstrates selective IPv6 route redistribution using route-map with interface matching. RIPng is the IPv6 version of RIP.

Test RIPng

Description

Test RIPng 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 IPv6 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 '2001:db8:100::1/64'
set interfaces dummy dum1 address '2001:db8:200::1/64'
set interfaces ethernet eth0 address '2001:db8:1::100/64'
set protocols ripng network '2001:db8:1::/64'
set protocols ripng redistribute connected route-map INTERNAL
set protocols ripng 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 '2001:db8:1::50/64'
set protocols ripng network '2001:db8:1::/64'
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Attention

Verify that dum0 route 2001:db8:100::/64 is advertised and learned

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

2001:db8:100::/64

Show output

Step 4: Run command protocols ipv6 show route at DUT1 and check if output matches the following regular expressions:

2001:db8:100::/64

Show output

Codes: K - kernel route, C - connected, L - local, S - static,

C>* fe80::/64 is directly connected, eth0, weight 1, 00:00:03

Attention

Verify that dum1 route 2001:db8:200::/64 is NOT advertised (not in route-map)

Step 5: Run command protocols ripng show at DUT1 and expect this output:
