Default-Information Originate

Test to verify RIPng default-information originate configuration. By default, RIPng does not advertise a default route (::/0) even if one exists in the routing table. The set protocols ripng default-information originate command forces RIPng to generate and advertise a default route (::/0) to all neighbors.

Test RIPng Default-Information Originate

Description

Test RIPng default-information originate sends default route to neighbors. DUT0 (2001:db8:1::100) is configured with set protocols ripng default-information originate to advertise the default route (::/0) via RIPng. The test verifies that DUT1 learns the default route via RIPng.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address '2001:db8:100::1/64'
set interfaces ethernet eth0 address '2001:db8:1::100/64'
set protocols ripng default-information originate
set protocols ripng network '2001:db8:1::/64'
set protocols ripng redistribute connected
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 ethernet eth0 address '2001:db8:1::50/64'
set protocols ripng network '2001:db8:1::/64'
set protocols ripng timers update 5
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Attention

DUT1 (2001:db8:1::50) is the neighbor that should receive and install the default route from DUT0 in its routing table.

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

R\(n\) ::/0

Show output

       R - RIPng, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,

                  fe80::dcad:beff:feef:6c00   eth0       2    0  02:58

Attention

Verify that RIPng default route is selected (R>*)

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

R>\* ::/0

Show output

Codes: K - kernel route, C - connected, L - local, S - static,
       R - RIPng, O - OSPFv3, I - IS-IS, B - BGP, N - NHRP,
       T - Table, v - VNC, V - VNC-Direct, A - Babel, F - PBR,
       f - OpenFabric, t - Table-Direct,
       > - selected route, * - FIB route, q - queued, r - rejected, b - backup
       t - trapped, o - offload failure
