Test RIPng Redistribute OSPFv3

Description

Test RIPng redistribute ospfv3 basic functionality across three routers. DUT1 (OSPFv3) announces a dummy interface route via OSPFv3. DUT0 (OSPFv3 + RIPng) learns the route via OSPFv3 and redistributes it to RIPng. DUT2 (RIPng only) learns the OSPFv3 route through RIPng redistribution.

Scenario

Warning

OSPFv3 router-id must be explicitly configured. If no IPv4 address exists on the system, OSPFv3 will fail to establish without a manual router-id.

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address '2001:db8:1::100/64'
set interfaces ethernet eth0 ipv6 ospfv3 area 0
set interfaces ethernet eth1 address '2001:db8:2::100/64'
set protocols ospfv3 parameters router-id 2.2.2.2
set protocols ripng network '2001:db8:2::/64'
set protocols ripng redistribute ospfv3
set protocols ripng 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 dummy dum0 address '2001:db8:100::1/64'
set interfaces dummy dum0 ipv6 ospfv3 area 0.0.0.0
set interfaces ethernet eth0 address '2001:db8:1::1/64'
set interfaces ethernet eth0 ipv6 ospfv3 area 0

Step 3: Set the following configuration in DUT2 :

set interfaces ethernet eth1 address '2001:db8:2::2/64'
set protocols ripng network '2001:db8:2::/64'
set protocols ripng timers update 5

Attention

Verify DUT2 learns only 2001:db8:100::/64 (matching route-map)

Step 7: Run command protocols ripng show at DUT2 and check if output matches the following regular expressions:

R\(n\) +2001:db8:100::/64

Attention

Verify DUT2 does NOT learn 2001:db8:200::/64 (filtered by route-map)

Step 8: Run command protocols ripng show at DUT2 and expect this output:
