Default-Metric

Scenario to verify RIPng default-metric configuration. This test validates that the default-metric command sets the metric value for redistributed routes. DUT0 configures default-metric 10 and redistributes a static blackhole route. DUT1 learns this route with metric 11.

Test RIPng Default Metric

Description

Test RIPng default-metric configuration where DUT0 redistributes a static blackhole route 2001:db8:200::/64 with default-metric 10 and DUT1 learns this route with metric value 11.

Scenario

Warning

This command does not affect connected routes even if redistributed by redistribute connected. To modify connected route’s metric value, please use redistribute connected metric or route-map.

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-metric 10
set protocols ripng network '2001:db8:1::/64'
set protocols ripng redistribute static
set protocols ripng timers update 5
set protocols static route6 '2001:db8:200::/64' blackhole
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

Verify that DUT1 learns route 2001:db8:200::/64 with metric 11

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

R\(n\)\s+2001:db8:200::/64[\s\S]+eth0 +11
