Test DHCP default route distance

Description

DUT0 is connected to the WAN side through the cellular cell0 interface. Additionally, distance of default route obtained via DHCP client is configured.

Scenario

Step 1: Set the following configuration in DUT0 :

set cellular profile CELPROFILE apn movistar.es
set controllers cellular wwan0 encrypted-pin U2FsdGVkX19rZDynSCnyxe6BP5c+kgW5Og9vl2GdGAk=
set controllers cellular wwan0 pdp 1 profile CELPROFILE
set interfaces cellular cell0 address dhcp
set interfaces cellular cell0 dhcp client receive default-router distance 200
set interfaces cellular cell0 phy wwan0 pdp 1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Run command controllers cellular wwan0 pdp 1 show network-data-connection at DUT0 and check if output matches the following regular expressions:

Connection status\s* = connected
Show output
Connection status               = connected
Traffic channel status          = active
Max. TX channel rate (bps)      = 50000000
Max. RX channel rate (bps)      = 300000000
IPv4 address                    = 5.205.125.204

IPv4 secondary DNS              = 80.58.61.249

Step 3: Run command protocols ip show route at DUT0 and check if output matches the following regular expressions:

S>.*0\.0\.0\.0\/0 \[200\/0\] via .* cell0,.*
Show output
Codes: K - kernel route, C - connected, L - local, S - static,
